Caribbean Island could benefit from its geothermal
“The volcanic island of St. Lucia plans to tap geothermal power trapped beneath sulfur springs and rolling mud pools in a rare attempt at developing alternative energy sources in the Caribbean.” 
Extract Geothermal Power
Although the details have not been fully released, the Associated Press reports that a US company plans to extract geothermal power from a location on the island where fumaroles are flooded with water warmed by hot rocks.
Geothermal energy is a form of renewable energy that is derived from the heat in the Earth’s core. Geothermal energy is extracted from the relatively stable earth core temperature of 54º to 56ºF using specifically designed geothermal supplies and equipment such as geothermal pipes, slotted pipes and geothermal fittings
Geothermal power is a sustainable, cost-effective, dependable and environmentally friendly. This form of energy stems from the planet’s formation, from radioactive decay and from the solar energy that is absorbed at the surface of the earth. 
Volcanic Island [3,4]
Saint Lucia is part of the Windwards Islands; it is situated in the middle of the Eastern Caribbean island chain. Saint Lucia is located roughly 34 km (21 miles) south of Martinique and 145 km (90 miles) northwest of Barbados.
The island covers an area of about 620 km2 (239 m2) and has a population of approximately 160,000. The island’s capital Castries, with a population of 50,000, is situated in the north western part of the island.
This volcanic island is the most mountainous of the Caribbean islands. A mountain range extends the length of the island with peaks varying from 100 feet to 3145 feet.
On the south western coast, two volcanoes Gros Piton (2615 feet) and Petit Piton (2461 feet) make up some of the Caribbean’s most renowned landmarks.
Tourism is vital to Saint Lucia's economy. Tourism is more popular in the dry season; tourists are attracted by Saint-Lucia’s tropical weather, beautiful scenery and abundant beaches and resorts.
Potential Geothermal Power
“The Sulfur Springs area where drilling is planned lies near St. Lucia's twin volcanic peaks, the Pitons, designated by UNESCO as a World Heritage Site. The peaks, formed by a volcanic eruption about 35 million years ago, shelter several bird species, giant ferns and wild orchids and are tourist attractions.” 
The location of the underground cauldrons is estimated to hold a reserve of 30 megawatts and to have a potential of an additional reserve of up to 140 megawatts.
Currently, the volcanic island of Saint-Lucia obtains all its electricity needs from oil-burning plants, which is very common throughout the Caribbean. This project would fulfill a long standing plan of the governments throughout the area to invest in alternative energy resources.
The realization of this geothermal energy project would provide an alternative energy resource from the oil that is currently imported as well as offer a bit of energy security to this small Caribbean island.

Horizontal drilling to reach a potential gold mine
Shale gas is very much in the news these days and it appears that this natural energy source could become the energy resource of the future in North America. Centered in Pennsylvania, the Marcellus shale formation, the largest shale deposit in the United States could possibility create thousands of jobs and supply the United States with its own fuel resources. This reservoir of natural gas could have major economic implications, not only for the U.S., but for the world.
This supply of cleaner burning fuel could potentially generate electricity that would result in 50% less greenhouse gas emissions than coal and cause less pollutants when powering motor vehicles.
This reservoir extends from New York State through much of north eastern and western Pennsylvania and through parts of West Virginia and Ohio. This shale formation has attracted billions of dollars in investments from companies all over the world. Within the next ten years more than 3 500 wells may be drilled by 70 companies, conceivably creating more than 200 000 jobs.
Shale gas refers to natural gas, primarily methane, which is found in fine-grained, organic-rich rocks, known as gas shales. Shale gas has become a significant source of natural gas in the U.S in the past ten years, and awareness of potential gas shales is increasing in Europe, Asia, Australia and Canada.
Gas “shales” are not a specific type of rock, but refer to various types of fine-grained particle rocks such as mudstone, shale, siltstone, carbonate rocks and fine-grained sandstone with layers of shale or mudstone. Gas shale refers to a reservoir or a trap where natural gas is contained.
Creation of shale gas
Shale gas is generated through any blend of primary thermogenic degradation of organic matter, secondary thermogenic cracking of oil or biogenic degradation of organic matter.
The exploration and production of shale gas is a technology driven industry since complex technologies are required to access the low-permeability reservoirs.
The horizontal drilling technique that is used in the shale gas industry enables drilling companies to access the gas from a distance, stay out of sensitive areas, reduce damage to the rock during drilling, maximize the drainage area of the well and decrease the visual impact by reducing the number of vertical wells.
Geologists believe that the Marcellus shale formation may contain up to 500 trillion cubic feet of natural gas, making it the second-largest reservoir in the world. This massive natural gas resource, which geologists have known about for 75 years, was thought to be inaccessible until ten years ago when producers began using high-volume hydraulic fracturing and horizontal drilling to access it.

Directional drilling, not just for well drilling
Horizontal directional drilling (HDD) has rapidly become the most valuable technology in the oil drilling business. Not only does directional drilling allow accessing areas that are otherwise out of reach economically, horizontal wells are now a favoured method to extract oil and gas. Directional drilling enables a larger contact with the productive area than vertical wells. Even though the HDD process may cost as much as two or three times the cost of a vertical well, the end result (e.g. the production factor) pays for itself as it can be as much as 15 to 20 times more advantageous.
Horizontal directional drilling is not only beneficial in drilling for gas and oil; today this technology is being applied to assist other areas as well.
Directional drilling to avoid traffic issues
In Mahoning County in Ohio, directional drilling is being used to install new sewer lines. This type of project inevitably causes traffic disruptions and destroys front lawns, streets and landscaping. The sanitary engineers in Mahoning County have turned to horizontal drilling to help solve the majority of issues relating to this type of project. Directional drilling allows workers to bore 500 feet at a time. This project, which consists of placing new 12 inch PVC pipe along a 4000 foot stretch, typically requires that a trench be dug the entire length and then entails landscaping, road work and clean up to complete the task. Using directional drilling, the crew digs underground for 500 to 800 feet and then pulls the piping through. With the use of horizontal drilling, the affected area is only about 40 feet in diameter, every 500 feet or so.
Directional drilling is a technology which enables drilling in areas and situations where traditional drilling methods would be unproductive, even impossible.
PVC Plus Drilling Products offers solutions for various types of drilling challenges by offering superior products and service. For more information regarding horizontal directional drilling, well drilling supplies, drilling fluids and HDPE pipe, contact PVC Plus Drilling Products.

Aloha to Geothermal Energy
On GoHawaii’s website1, Hawaii’s Big Island is described as allowing adventurers or romantics to discover an assortment of unparalleled natural wonders. The Big Island, the biggest and youngest of the five Hawaiian islands making up this U.S. State, is home to one of the world’s most active volcanoes, Kilauea; the tallest sea mountain in the world, Maunakea; the largest mountain in the world, Maunaloa, and the biggest park in the state, Hawaii Volcanoes National Park. Soon, the Big Island of Hawaii may also be able to pride itself as being a supplier of its own electricity using geothermal energy.
Local communities which are built on and around the volcano Kilauea have always respected the power and revered the goddess of the volcano, Pele. The realities of enormous utility costs and draining fossil fuel resources are forcing Hawaiians to consider using the power of Pele to sustain the future island’s economy and its residents.
Using geothermal energy to produce energy from the heat of Pele is a mixed topic amongst the Hawaii people. The belief is that as long as the volcano is active and producing heat, the energy should not be used or controlled in any way or form. In the traditional Hawaiian way of thinking, geothermal energy is not encouraged.
Other Native Hawaiians, who are very respectful of the environment as well as the need for alternative energy resources, offer different perspectives on the use of geothermal energy on the Big Island. On the one hand, using geothermal energy to benefit from the power of Pele can be considered sacrilege; on the other hand, this natural heat and energy source can be taken as a gift from the goddess Pele to help surmount hardship.
Astronomical energy costs
Many Hawaiians cannot make ends meet due to the astronomical costs related to coal, oil and gasoline on the islands. Currently, a 30-megawatt power plant which has been operating a closed geothermal system for nearly 17 years, employs 30 full-time employees, contributes 3 million$ to the local economy and provides approximately 20 percent of the Big Island’s electrical needs. The geothermal company also pays royalties to the State of Hawaii since the underground steam is deemed to be a state-owned resource.
Earlier in the year, the Hawaii Geothermal Working Group was formed to verify the feasibility of geothermal energy becoming the principal energy source that would supply the base-load demand for electricity on the Big Island.
This group’s report, which is expected in early 2011, will be used to promote the Hawaii Clean Energy Initiative. The goal of this Initiative is to have renewable energy resources make up 70 percent of the state’s consumption by 2030.
According to many, several of the most obvious obstacles to converting to geothermal energy are the lack of investors and money to explore new wells and to construct new facilities.
With the potential to give Hawaiians affordable and sustainable energy resources by tapping into the Big Island’s enormous source of renewable energy, it seems that many Islanders may soon welcome the use of geothermal energy as they welcome visitors to their beautiful island paradise.

PVC pipe critical for use in aquariums
PVC piping has long been used in aquariums to make certain the water circulating through the tanks is clean and filtered. PVC pipes are extremely resistant to the accumulation of clogging and corroding bio film, a slimy layer of bacteria which tends to develop in the tanks.
The Scripps Institution of Oceanography and the Georgia Aquarium, two world renowned centres, rely on the characteristics of PVC piping to maintain the purity of their huge tanks.
- The Scripps Institution of Oceanography, located in San Diego, California, is not only one of the most important centers for ocean and earth science research, education, and public service in the world, but it is also amongst the oldest and the largest.
- The Georgia Aquarium is the largest aquarium in the world. The aquarium houses 500 different species and more than 100,000 animals. Visitors to the Ocean Voyager exhibit at Atlanta’s Georgia Aquarium view a tank that is the length of a football field and contains 6.3 million gallons of salt water. Visitors do not see the life support system for all the creatures which constitutes in 10 miles of PVC pipe behind the massive tank.
PVC pipe specifications
- Durability and smoothness
The low friction on the inside of the PVC piping, limits biological growth, such as algae, crabs and mussels. PVC piping is low maintenance and very durable.
In Los Angeles, the Cabrillo Marine Aquarium still relies on its original PVC piping system that was installed in 1981. The nearly 30 year old pipes have never needed repairs.
The salt water used in many aquarium tanks is extremely corrosive. PVC does not corrode; therefore the pipes do not leak or allow chemicals to trickle into the water, affecting fish and plant life.
- Efficiency and limited space
PVC is easy to install, cut and configure. As well, PVC piping necessitates a less significant turning radius than other piping material, saving space in smaller areas.
Closed filtration system
The Georgia Aquarium, located in Atlanta, far from the coast, produces its own artificial salt water. The water is made once and then continuously recycled and disinfected by multiple filters in a closed system. PVC pipes connect all stages of filtration and heat exchangers. The PVC pipes then return the clean water into the tank.
Horizontal directional drilling
When the Scripps Institution of Oceanography needed to replace sections of its filtration system’s piping, contractors relied on horizontal drilling to bore a path for the new PVC piping that would replace the run down concrete pipes. Horizontal drilling limited the disturbances on the Institution’s campus, and the flexibility of the PVC pipes enabled the workers to pass the pipe through underground areas which were crammed full of existing utilities. Upon completion of the project, more than 4,000 feet of PVC pipe was used.
Today, the use of PVC piping is no longer limited to natural gas and drinking water. PVC piping is widely used. In many conditions, PVC is a better choice than other materials as it is non-corrosive, durable and amongst the simplest material to utilize and configure.
PVC Plus Drilling is an important supplier of PVC pipes and fittings. PVC Plus Drilling manufacturers slotted PVC pipe screen in horizontal and custom patterns, distributes Teflon, CPVC, Stainless Steel and HDPE pipes and fittings, as well as being a key PVC pipe supplier.

Mineral exploration and high-tech goods
Lanthanum, europium and neodymium: these rare earth minerals play an important role in clean power generation. Rare earth minerals are naturally occurring metallic elements that are used worldwide in tiny amounts to manufacture many of the high tech goods that we are so dependent on today.
These minerals hold particular chemical and physical characteristics which make them essential to the high-tech industry. The increase in high-tech toys has nearly doubled the demand for rare earth minerals since the last decade.
To fulfill this need, mineral exploration and drilling must be used to extract these elements from the earth.
Accuracy of a name
While these necessary minerals are labelled “rare earth elements”, the British Geological Survey compares the available quantity of these elements to that of lead and copper.
Near production monopoly
China owns approximately 35% of the estimated world reserves of these rare earth minerals (36 million tonnes in comparison to the United States’ 13 million tonnes); in addition, China controls about 97% of the production and transformation capacity of these rare earth minerals.
In the fall of 2010, China began limiting exportation of these prized mineral (as of October 2010, China had reduced its exportation of rare earth elements by some 70% from 2009); for countries that rely on these minerals to remain competitive in the high tech world, cuts in exportations could have huge repercussions.
Desert mineral reserves
The Mojave Desert, located in California, may hold the key that will release the United States from its dependence on another nation to supply it with rare earth minerals.
This desert is home to a mine that holds the minerals that have become essential to the high tech world. This mine, shut down since 2002 when the United States relinquished the rare minerals exploration market to China, is the biggest known rare earth elements deposit outside of China.
The world’s demand of rare earth minerals is 125,000 metric tonnes per year. Educated guesses place the demand for these minerals at 205,000 metric tonnes by 2015, some 80,000 tonnes more than the current demand. The Mojave Desert mine, producing at total capacity, is believed to be capable of turning out 20,000 metric tonnes a year; a tad more than the United States’ present demand.
In spite of the fact that sufficient rare earth minerals may exist on US soil, it is unclear whether the country has obtained enough knowledge and expertise to successfully alter the critical minerals into serviceable components for the manufacturing of high tech devices.
One of the largest and most challenging markets in the industrial drilling industry, mineral exploration is dependent on a number of factors such as geologic conditions, operator requirements, drilling methods and environmental concerns. These and other factors stress the importance of using the proper drilling fluids and well drilling supplies. PVC Plus Drilling Products has the solution for reduced core recovery or problematic hole conditions. For more information contact PVC Plus Drilling Products.

Horizontal drilling to uncover unexploited oil
A hundred and fifty years since its unearthing, oil maintains its critical role in the world’s economy. It seems that ever since the world has become dependent on oil, it has worried that its reserves will run out.
Although oil is a primary source of energy for many countries, its positioning has been re-evaluated since the energy shortages in the 1970s and 80s where the developed world was forced to realize how dependant it was on petroleum products and vulnerable to deficits in supply. In the early 1970s, 46% of the global energy consumption was oil; in 2005, oil accounted for 35%.
Today, oil still tops other energy source on a worldwide scale (nuclear power covers 6% of the world’s energy needs, natural gas covers 20% and coal, 25%).
The world is very dependent on oil and the primary reason is that oil possesses some very interesting characteristics. Oil offers optimal energy in a small volume, making it easy to transport.
Also, using distillation, oil can be separated into other products such as gasoline, kerosene, bitumen and paraffin.
Maximum oil production
Many theorists predict that the oil production has reached its maximum potential and that current output levels are not maintainable.
As of yet, the oil industry has maintained, even raised, its production by using newly available technologies: deep water drilling, three dimensional seismic imaging and horizontal drilling.
Horizontal drilling consists in drilling horizontally into rock, pumping water, sand and drilling fluids into the gaps in order to split the shale.
It seems that the price of oil is constantly increasing and dropping; in the past ten years, the cost of a barrel of crude oil has risen steadily from 2002 to 2007, peaking at $147 in 2008 to then crash to $33 a barrel some 6 months later as a result of a worldwide recession which largely affected demand. In 2010, with some economic revival, the barrel price had gone back up to $80 and, so far, in 2011 the increasing price in energy costs is bringing back memories of 2008; suddenly, oil is back up to $100 a barrel and, amidst fears of long term Middle East interruptions in supplies, this will likely increase further.
Horizontal drilling: new opportunities
Fortunately, technology is allowing companies to explore oil and gas reservoirs that were previously deemed inaccessible, either economically or technically. Horizontal directional drilling is opening up new opportunities such as accessing poor quality rock that would have been considered far too costly to access using conventional vertical drilling. Horizontal drilling has re-energized the drilling industry by enabling oil to be located and accessed in areas that remained untapped in the past due. It is estimated that horizontal drilling techniques will elevate oil production in the United Stated by roughly 20% over the next 4 or 5 years.

Campus going green thanks to geothermal energy
The University of North Carolina at Chapel Hill’s Botanical Garden, a leader in native plant conservation and education in the southeastern United States for more than 30 years, is a "conservation garden." The mission of the garden is to inspire understanding, appreciation and conservation of plants in gardens and natural areas and to advance a sustainable relationship between people and nature. True to this mission, the UNC Botanical Garden’s Totten Centre is one of the most sustainable and energy efficient buildings amongst all the UNC buildings. This is due in large part to its geothermal heating and cooling system that enables the building to saves on nearly 50 percent of its energy expenditures.
Geothermal energy is a form of renewable energy that is derived from the heat contained in the Earth’s core. Geothermal energy is extracted from the relatively stable earth core temperature of 54º to 56ºF. Even in colder areas, the ground contains heat; at a depth of 10 feet, the ground is a constant 55ºF. Geothermal heating is a practical and energy saving alternative for heating and cooling a building. A nearby water source is used as a heat sink in the warm months and heat source in the winter month.
Geothermal is an environmentally friendly means of heating and cooling because it does not require as much non-renewable energy and fossil fuel to reach the same temperature as other systems. A geothermal system is also less expensive to operate than traditional heating and cooling systems.
At the Botanical Garden’s, a closed loop geothermal coil system heats and cools water. In a closed loop system, the most popular type of geothermal installation, water is circulated throughout small diameter loops. A closed loop system can be set up vertically or horizontally in the ground, or submerged in water.
At UNC, water from deep wells (3500 feet) within the botanical garden is circulated through the underground geothermal coils. These coils, nearly three and a half miles of closed pipes, use the earth’s constant temperatures to cool or heat water according to a thermostat setting. The geothermal pipes run to and fro the wells to the building. In essence, the water, which is simply used to carry warmth or freshness, is cooled and heated again and again.
The Botanical Garden's Education Center has been given the U.S. Green Building Council's Leadership in Energy and Environmental Design’s platinum certification, the highest award for green buildings.
PVC Plus Drilling Inc. supplies a complete range of drilling products and geothermal accessories that are used in geothermal heating and cooling installations. PVC Plus Drilling can supply you with geothermal fittings, slotted pipe, geothermal grouts and HDPE geothermal pipes.

PVC Pipes the answer to rampant water main breaks
Thanks to its resistance to corrosion and its overall durability, PVC (polyvinyl chloride) pipe is a very popular choice for use in clean water distribution systems and the sanitary collection of waste water. At present more than 70% of the new underground water distribution pipes in the United States and Canada are PVC; 75% of the newly installed sanitary sewage systems use PVC piping.
Broken water mains and aging and corroded metal pipes are responsible for some 2.3 trillion gallons of treated water being are lost every year in the United States. As a result of these failing systems, more and more cities are resolving the issue by installing PVC pipe systems that are intended to last into the next century.
Today’s economy and fast paced society rely on many infrastructures, but the water delivery and wastewater handling infrastructure are likely the most critical. In the United States, nearly 265 million people depend on drinking water systems for clean water. In Canada, more than 31 million residents count on drinking water systems to provide them with safe water.
- Wastewater systems keep our wastewater systems safe for recreational activities by preventing billions of tons of pollutants from accessing rivers, lakes and coastlines
- Wastewater systems keep us safe from water-borne disease by reducing illness and related healthcare costs.
- Efficient and reliable systems enable our society by promoting a $50 billion a year recreation industry, some $300 billion in coastal tourism and $45 billion in commercial fishing;
- The manufacturing industry, which generates hundreds of billions of dollars annually, depends on clean water;
- Clean coastlines, rivers and lakes promote investments in an area which enhances land value, promotes job creation, and increases taxes.
Daily water main breaks
The importance of these water systems is put into light on a daily basis in many communities as the dependability of these critical systems are deteriorating at an alarming rate. Corrosion and failures are threatening safe drinking water and sanitation services; in North America alone, some 700 water main breaks occur every day!
The popularity of PVC to replace old water mains and its use in newly installed systems is certainly as a result of its greater durability.
In a survey supported by the American Water Works Association Research Foundation, 162 responding utilities rated PVC pipe as having a durability of 4.1 on a scale of 1 to 5; this rating was the highest amongst all pipe material.
A two-year study carried out by the National Research Council of Canada found that PVC piping has only 0.7 breaks per year for every 100 kilometres of water distribution piping laid. In comparison, cast iron accounts for 35.9 breaks and ductile iron 9.5 breaks.
Every time a pipe fails the resulting costs are enormous, not only to repair the pipe, but the overheads for clean up, business disruptions and resulting illness outbreaks.
PVC is a versatile product that can be used to pump fresh water into our homes to the toy that will entertain your toddler.
Product made from PVC will not disintegrate or corrode, and require very little maintenance. The ability of PVC to bend and flex without breaking makes it an ideal choice for piping as it is able to handle ground movements caused by unstable or shifting soils, as well as earthquakes.
Less energy is used to produce PVC than many of its rival components and as much as 20% less energy than other plastics. PVC’s most important raw material, making up almost 60% of the vinyl, is derived from common salt, saving on fossil fuels.
Vinyl is recyclable and all types of products can be remade into other products.
PVC pipes have been used in drinking water and wastewater systems since the 1950s. Today, a large number of these installations have been thoroughly tested for reliability and safety. These PVC pipe systems are extremely resistant to internal and external corrosion, transfer clean drinking water, and offer a greater flow, are resistant to cracking, even when they are bent or exposed to extreme loads, as well, PVC pipes offer water tight joints.
An important supplier of PVC pipe and fittings, PVC Plus Drilling products makes slotted PVC pipe screen in horizontal and custom patterns and distributes Teflon, CPVC, Stainless Steel and HDPE pipes and fittings.

Geothermal energy, horizontal directional drilling
Geothermal heating uses the natural and constant warmth that is stored in the earth’s core. Geothermal energy has been used for thousands of years. Both the Romans and the Native Americans used the natural heat supplied by hot springs. In the present time, incessant trepidation regarding energy concerns and costs have improved interest in geothermal power.
Geothermal energy is all the rage now as people seem to be learning more about this natural form of renewable energy.
Geothermal energy is used in different ways:
- To generate electricity indirectly
- To heat buildings through direct-use methods
- To cool and heat buildings by means of geothermal heat pumps
Geothermal pipe and geothermal earth loops that are used in geothermal cooling and heating systems are specifically designed from high density polyethylene pipe (HDPE pipe and PVC piping)
Here are some interesting geothermal facts:
- Geothermal energy is considered a renewable energy source since the earth constantly generates heat
- While the surface of the earth can become quite cool, even cold, the temperatures at the center of the Earth can attain several thousand degrees.
- Geothermal energy can supply both heat and electricity.
Heat from the earth
- The word “geothermal” comes from the words “geo” meaning “earth” and “thermal” meaning “heat”.
- The earth’s core temperature increases as you dig; for every 100 meters (328 feet) below ground, there is an increase in the rock temperature of approximately, 5.4˚ Fahrenheit (3˚Celsius).
- Geothermal energy is commonly acquired by accessing geothermal springs (also known as hydrothermal sites); these areas are geologically active area where water seeps into the
Earth's crust, is heated by the Earth's core and then rises to the surface of the earth in the form of steam.
Geothermal power worldwide
- Geothermal power is produced in more than 20 countries worldwide (eg: the United States, Italy, France, Iceland, New Zealand, Mexico, Nicaragua, Costa Rica, Russia, the Philippines, China and Japan, to name a few)
- More than 25% of Iceland’s electrical energy is produced from geothermal sources; nearly 90% of homes in Iceland are heated by geothermal heating.
In geothermal heating and cooling, vertical or horizontal drilling (eg: horizontal well drilling) wells bore into the ground to reach the constant core temperatures. A thermal loop, made out of geothermal pipe, is then created to enable the heat to be transferred to fluid within the HDPE pipes. The thermal loop is composed of a series of geothermal pipes connected using geothermal fittings. The geothermal pipes (HDPE pipes and PVC pipes) have exceptional physical and thermal characteristics. The geothermal pipes carry a fluid which connects the geothermal system's heat pump to the underground.
Geothermal power plants
- In comparison to other forms of power facilities, geothermal power plants leave a very small footprint on area in which they are located.
- Geothermal electricity plants offer a constant source of power; operating generally more than 95% of the year.
- Italy is home to the first geothermal power plant that is still in operation today; the plant started operating in 1904.

Groundwater—protecting our most valuable resource
With only 3% of water on earth being freshwater, life on earth depends upon the security and maintenance of this most valuable resource. Here in North America, we typically think of lakes and flowing rivers as our sources of freshwater—in particular the Great Lakes, which are shared between Canada and the United States. In fact, this couldn’t be further from the truth. In their book The changing earth: Exploring geology and evolution, J.S. Monroe and R. Wicander suggest that 97% of North America’s freshwater lies beneath the earth’s surface, in aquifers. This groundwater is used in varying degrees across North America. In Canada, for example, less than half of the population of Quebec rely on groundwater, whereas almost everyone on Prince Edward Island depends on groundwater for their drinking water. And from an agricultural perspective, over 75% of farms and ranches across Canada rely on groundwater for irrigation.
Despite the importance of groundwater reservoirs to North America, these supplies are under threat from over pumping and, in particular, pollution. Nitrates from pesticides and fertilizers have contaminated most groundwater that lies below agricultural land—though at present the level of pollution does not pose a health risk. And in urban areas, gasoline, oil and salt from winter gritting leeches into groundwater supplies and pollutes them. Salt is also a risk from rising sea levels. Some scientists suggest salt water is bound to infiltrate low-lying reservoirs of groundwater, rendering them unfit for human consumption.
Thankfully, there’s still hope, especially for Canada. With the country’s tiny population but large geographic size, most Canadian groundwater has yet to be affected by either over pumping or pollution. How Canada goes about managing and protecting this resource will have implications around the world.

Warming up to geothermal energy
Using the relatively constant temperature that exists just below the Earth’s surface is a renewable and environmentally friendly resource for heating and cooling that’s gaining popularity around the World. And as the cost of installing geothermal heating and cooling systems continues to fall, this trend is set to continue and become even cheaper and more efficient.
In Australia, shares in geothermal companies closed up to 25% higher on July 11. The hike followed an announcement by the federal government there that a new carbon tax is to be introduced to help fund $13.2 billion (Aus) in investment of renewable energy sources.
Closer to home, In Aspen, Colorado, city officials are planning to drill a well in the hopes of tapping into geothermal resources that are believed to be below the ground there. With local projects aiming to reduce greenhouse-gas emissions by up to 80%, Aspen officials see geothermal energy as a step in the right direction. The goal is to use the geothermal energy to heat and cool buildings in the Aspen area.
Although geothermal energy is not generally recognized as being suitable for anything other than small applications in homes and offices, this isn’t actually the case. Most media attention and marketing from geothermal companies is aimed at the consumer. But drilling deeper into the earth’s surface can offer heating sources that will power much larger applications, such as turbines in power plants. This is because the deeper into the earth’s crust you drill, the warmer the temperatures you find, especially in areas with volcanic activity.
For over a decade, PVC Plus Drilling Products Inc. has been helping its clients progress through innovation. PVC Plus Drilling recognizes that in order to be unique and achieve a competitive advantage, the company must offer custom manufactured screen pipe products and solutions.

The problem with our landfills and pollution
Landfills were supposed to be the answer to our garbage-disposal issues. Over time, however, they have caused as many problems as they appear to have solved. It is estimated that there are over 8,000 fires at landfills across the United States each year? How are these fires started? Heat from decaying garbage can become hot enough to ignite gas below the surface and cause fires that burn under or above ground for miles.
Gas from decaying garbage is a major issue. If the conditions are right, A single ton of garbage can produce up to 500 cubic yards of gas. All landfills produce potentially explosive emissions. In modern landfills, the gas is channelled away by PVC pipe and burned off, or perhaps used as an alternative energy source. But when landfills first began appearing, back in the 60’s, many of the safety measures in place today were not considered. There could be up to 10,000 landfills in the United States alone that have zero safety measures in place.
Another major problem with older landfills is the pollution of groundwater. As organic garbage decomposes, the bacteria created leech into the soils and eventually—with the help of rainwater—find their way into the groundwater system. Heavy metals, oil, gasoline and solvents can also leak into these precious water supplies. Many cities and communities in North America rely on groundwater alone for their drinking water, so the repercussions of having this supply contaminated by decaying landfill refuse are serious.
We have become much more aware of the potential environmental issues of landfills here at home. By utilizing PVC pipelines to channel waste gases and liquids safely away from landfill sites and improving landfill design, these garbage-disposal sites have become much safer. But here is still much to be done to make older landfills safe both here and in the developing world—where huge landfills pose a major health risk to local populations.
PVC Plus Drilling are a leading supplier of PVC pipe, fittings and drilling-related products that are utilized for a range of applications including groundwater sampling and testing, and pipeline constructions for landfills.

Celebrating the advent of PVC pipe
Remember how lead piping was supposed to have contributed to the fall of the Roman Empire? Turns out that actually this might not have been the case. The Romans were a clever bunch and used lead piping to channel water extensively in Rome. But it seems that the supposed lead poisoning of the population from lead leeching into the water supply is wide of the mark. Why? Because Rome is built on sedimentary calcareous soil which, according to John Scarborough, a noted pharmacologist, caused limestone encrustation around the pipes. This encrustation required regular cleaning, which in turn caused deposits of calcium carbonate to build up in the pipes. This build up protected the pipes from corrosion, and formed a barrier that stopped lead deposits from leeching into the water supply.
This was a very good thing, because lead is nasty stuff—real nasty. The toxicity of lead is such that it can wreak havoc on all the major systems of the body. Overexposure to lead can kill.
Lucky, then, that as far as water is concerned, we can rely on PVC piping to channel our supplies. But PVC is far more widely used than simply to channel our drinking or waste water. According to the PVC website, PVC is one of the most used plastics in the World today. Demand for PVC exceeds 35 million tonnes per annum, and the product has an average global growth rate of 5%. PVC is used in building and construction, health, transportation, packaging and throughout our everyday lives—all in all, PVC pipes have many benefits.

Geothermal energy on the rise in Canada
Some of the latest news from the Canadian Geothermal Energy Association:
On September 14 and 15 this year, the Canadian Geothermal Energy Association will be holding their fourth annual conference. According to their website, this year’s conference will feature Canadian development, activities by developers internationally, drilling and drilling services, geothermal direct use applications, policy needs, power plant options and an investment forum about the financing of geothermal projects and the potential insurance of exploration risk. The event will also feature two workshops on geothermal energy.
This edition of the event is expected to be particularly upbeat given the recent news coming out of Ottawa and the headquarters of the Geological Survey of Canada (GSC). According to a recent report conducted by GSC and a team of scientists, electricity generated by geothermal energy could cover 10% of Canada’s current electricity generation. Other highlights of the report include:
• Geothermal energy potential is distributed across Canada
• Canada's in-place geothermal power exceeds one million times Canada's current electrical consumption
• Canada has significant potential for geothermal energy development
• Research on decreasing installation costs could facilitate further exploitation of abundant low-temperature geothermal resources.
• Geothermal installations could displace other more costly and environmentally damaging technologies
Overall, this represents great news for the geothermal energy industry. As well as offering a potential market worth billions of dollars, the industry could help create thousands of new jobs across the country. Canadian developers, technology and service firms are already active globally and represent activities across the World, including United States, South America and Europe.
For over ten years, PVC Plus Drilling Inc. has been a leading supplier to the growing geothermal industry. The company supplies a full range of PVC geothermal pipe, geothermal fittings and accessories.

Fresh water Earth’s most precious commodity
While the many conflicts over oil have been a staple diet for our media outlets since black gold was first discovered, conflict over water is less widely reported—but it happens, too. The Six Day War, in June 1967, was the culmination of rising tension between Israel and its Arab neighbors. One of the causes of this tension was Israel diverting water from the River Jordan, to help irrigate the Negev Desert. In response, Syria tried to divert water away from Israel, but the construction work was destroyed by Israeli forces.
It’s estimated that within 20 years, the demand for freshwater will outstrip supply by up to 40%. If this is the case, then we can expect to see more conflicts fought over water than ever before.
Although water covers around 70% of the Earth’s surface, 97% of it is salt water, contained in oceans, seas and bays. This leaves just 3% of fresh water contained on the earth’s surface. Of this, 2.4% is contained as ice in glaciers and polar caps, with only 0.6% in the form of freshwater bodies such as lakes or rivers.
In fact, by far the largest supply of the world’s fresh water (around 1.6 %) lies below ground, in aquifers. For example, the Ogallala aquifer, found beneath the Great Plains, in the U.S., covers around 174,000 square miles. The aquifer supplies drinking water to around 82% of people that live within its borders.
The challenge for groundwater, as with oil, is to locate it and extract it—but there’s more. Unlike oil, many of the Earth’s aquifers are naturally replenished...albeit slowly. So the added challenge with this planet’s most valuable commodity is to manage the resources effectively to ensure that supply doesn’t exceed replenishment.

Tips for good well servicing and maintenance
With around 25% of Canadians and close to 50% of Americans relying on groundwater for drinking, there’s a lot of municipal and private wells that need to be maintained to ensure safe supplies. While most municipalities that have wells will use a regular contractor for well inspection and maintenance, contracts will come up for tender from time to time. And for residential properties, every time a home with a private well changes hands, the buyers (If they are doing their job properly) will consult a contractor for a detailed well analysis before signing. It’s big business and can prove very lucrative for contractors, especially those that operate in areas with a high concentration of wells. To put a potential home owner at ease and improve your company’s chances of securing a long term contract, it pays to be comfortable with the mechanics of well inspection and maintenance.
There are three main types of water well—drilled, bored or dug. Bored and dug wells are usually situated above shallow aquifers, while drilled wells are used to extract water from deeper aquifers.
When inspecting a well for a client, the following checklist should be adhered to:
- Ensure there is a copy of the well record on hand for reference. The well record contains all the data about the well—history and specs.
- Check that the well is at least 50 feet away from any potential sources of contamination.
- Make sure the well cap is at least a foot off the ground and watertight.
- See that the ground slopes are away from the casing and that the casing isn’t cracked or damaged in any way.
- Check that the pump and all associated piping is in good condition.
- Ensure a 12-foot wide grass buffer is maintained around the well head.
- Check the tap strainer inside the house for signs of sand or grit, which would indicate a corroded well screen.
Finally, recommend that the buyer takes at least three water samples over a period of seven days and has them tested to ensure cleanliness of the water source.

Using desalination to solve our water woes
A recent public hearing in Santa Cruz, California’s largest city, about desalination brought a controversial topic to the fore once more. On one hand the proposed plant is a boon, replenishing possibly dwindling freshwater resources for around 150,000 people. On the other side, though, the proposed price tag of over $100 million makes the project a potential bust.
If you think the wars fought around the world over oil have been bad enough, you may have not seen anything yet. Just wait until water becomes really scarce.
Considering that around 71% of the Earth’s surface is covered by water, and that over 97% of the Earth’s water is salt, you’d think we had a plentiful potential supply of fresh water...with a little tweaking.
Unfortunately, it’s the tweaking that’s the problem. That, and as the Santa Cruz hearing admirably demonstrates, the cost. There are around 15,000 desalination plants around the world at the present time, but together they produce less than 1% of our water use.
Desalination has historically proved and continues to prove today to be a tough nut to crack.
Early attempts at desalination centered around a cascading system of chambers in which salt water was boiled at ever-decreasing temperatures, essentially producing freshwater vapor from the salt water. In the 50s, the U.S. Government began investigating osmosis through permeable membranes—like the way the cells work in our body. First attempts had limited success, but the design of the membranes quickly improved and so have the results.
And that’s where we are today, with scientific advances—such as the advent of PVC pipes and fittings that has virtually eradicated the costs of replacing corroded pipes—at the same time improving the desalination process and reducing the cost of operation. While desalination as a total cure for our water woes seems still to be a bit of a stretch, it certainly seems as though it can be a vital tool in our water-management tool kit.

The rise of geothermal energy
Of the big three renewable energy sources (geothermal, wind and solar), geothermal is currently the weakest link. Despite a major push across North America in recent times to increase energy generation from renewable sources, geothermal energy accounted for less than half of one per cent of all energy production between january and August of 2011.
Part of the slow rate of growth for geothermal technology comes from the accessibility issue. You can check out North America’s hot spots on Google Earth. There, you’ll quickly see that the easiest place in North America to harness geothermal energy is the Western United States. Here, it is relatively easy to drill and tap into underground water reservoirs where water is heated to well over 500 degrees fahrenheit (260 degrees celsius). The steam from these hotspots is channelled to power turbines that produce electricity.
But thanks to technology, accessibility to geothermal energy is improving all the time. For example, by using lower-temperature water (even less than 135 degrees fahrenheit or 57 degrees celsius) to heat a secondary liquid—one with a lower boiling point—the resultant steam can be used just as readily to power turbines to produce electricity.
This opens up far more of the planets crust to potential geothermal energy production.
The bottom line is that geothermal energy is a fantastic resource that should be utilized as much as possible. It’s relatively cheap to build, operate and maintain, and it produces little in the way of pollution.

Landfills Not for Trash Talking
In the developed World, there are many things that we are good at, and somewhere close to the top of the pile must be our ability to make garbage. And all that garbage has to go somewhere.
Over 90% of garbage in North America is disposed of in sanitary landfills.
Environmentalists will tell you that landfills are dangerous, releasing potentially explosive methane gas into the atmosphere and toxic chemicals into the ground that poison our precious water supplies. The truth of the matter is that landfills are a generally very safe and secure way of disposing of garbage. A landfill:
- is a single, specific location for garbage that can be easily managed and monitored
- offers the opportunity for waste to be sorted and recyclable materials removed
- can be monitored to filter organic waste that can be collected and used elsewhere
- is sanitary because leachate collection systems are installed to protect groundwater
At the present time, there are no alternative cost-effective ways to dispose of the enormous amount of garbage we produce. And, short of letting it pile up in our homes or along our roadsides, landfills are a proven and reliable way to manage our trash.
PVC Plus Drilling Products specialize in products used in leachate and wastewater collection and management. As a leading supplier of PVC pipe and fittings, PVC Plus Drilling Products wholesales to North American and international distributors and consulting firms.

Finding a custom pipe manufacturer you can trust
There’s one child’s toy that’s always a pleasure to watch young children play with. It’s the one where children have to fit plastic shapes into corresponding holes in a base. There’s a square, a circle, a triangle and a rectangle. It’s entertaining to see children struggle at first as they try to fit a square peg into the round hole. It’s also a pleasure to see the triumph on a child’s face when it matches a peg with the right-shaped hole, and the shape slides easily into place.
Most of the industrial and commercial practices that require well drilling are like that child’s toy—no two holes are ever the same. And that means the products that line those wells or need to be placed within them sometimes need to be custom made, too.
Sometimes standard pipe and fitting sizes just won’t do.
Luckily, for all types of vertical welldrilling and horizontal well drilling applications, you can rely on PVC Plus Drilling Products.
At PVC Plus Drilling Products, we specialize not only in standard sizes, but we also specialize in the manufacture and supply of custom products, too.
We can supply your company with PVC pipe, stainless steel pipe, slotted screen pipe, flush mounts, well caps and much, much, more. We appreciate that when your company is drilling, time literally becomes money. And by having us in your corner, you can keep your down time to a minimum.

Does your supplier have the best practices
Manufacturing is built around productivity, and the beginning of a new year is an ideal time to examine your suppliers to see how they measure up. Sales are not the only driver of profitability; lean manufacturing principles and maintaining maximum productivity are also key components. Together they can help your suppliers offer you the most competitive rates in the market place and ensure your orders are delivered on time. Because nothing eats away at profit more than downtime on a job or project.
There are a number of components that manufacturers can review to improve productivity and order fulfillment, including:
Machinery and tools
Investment in top-quality tools and machinery means better reliability and less down time for repairs or routine maintenance. Wherever possible, machine operators should be trained to do basic maintenance/repairs to further maximize productivity.
Standard operating procedures
All production jobs and machines should be work studied and have a standard set of operating procedures compiled. Operating procedures should be prominently displayed at each work station.
Raw material and product handling
The less time spent handling raw materials and product, the better. Poor management of raw material and product handling is one of the biggest drains on productivity in manufacturing.
Defects and corrections
Defective work, or work that requires correction is essentially zero productivity that still costs time, energy and wages. Defects and corrections must be cut from production as much as possible.
Shift changes, machine set up and work flow
Productivity can be dramatically increased by reducing shift-change and machine set-up time, and by reviewing and tweaking product flow across the factory floor to minimize unnecessary twists and turns.
During a decade of manufacturing and designing environmental drilling products, PVC Plus Drilling Products has established itself as a leader in the manufacture and supply of geothermal pipe, geothermal fittings and well drilling supplies for the geothermal and mineral exploration and extraction industries.

PVC can fix the country's crumbling infrastructure
At the time of writing this article, it was estimated that there had been 516 water-main breaks in North America during the preceding 15 or so hours. According to watermainbreakclock.com, there are 850 water main breaks in North America every day, costing over $50 billion dollars to repair.
The number one reason behind this epidemic? Corrosion, the visible sign of a crumbling infrastructure that requires billions upon billions of dollars just to repair and maintain—let alone upgrade to a better, more efficient system. When our city sewage and drinking water systems were first set up, cast iron was the pipe material of choice. Then ductile iron gradually replaced it. Both are susceptible to corrosion. And to add salt to the wound—literally—rock salt is still commonly used across Canada and northern U.S. states to clear roads of snow and ice in winter—further accelerating the corrosion of our sewage and drinking water systems.
What’s the answer? PVC
PVC pipe is now the predominant material used in waste-water applications, and it should be the natural choice for drinking water systems, too. PVC pipe is available in a variety of lengths, diameters and pressure classes.
Despite vocal protests that PVC is not safe, over 60 years of continuous testing has proved otherwise, with PVC meeting or exceeding all health and safety standards and regulations governed by the U.S. and Canadian Safe Drinking Water Acts, and other international statutes.
PVC Plus Drilling Products Inc. is a leading supplier of PVC pipe and fittings, PVC Plus Drilling products manufacturers slotted PVC pipe screen in horizontal and custom patterns and distributes Teflon, CPVC, Stainless Steel and HDPE slotted pipes and fittings.

PVC pipe and water preservation
Right now, wars are being fought over oil. In the future, it's likely that wars will be fought over another precious yet dwindling resource...water. And when that happens, Canada will be a superpower. Canada is home to around 9% of the planet’s renewable water supply.
But unlike oil which, with a little effort and investment, can be replaced by another source of energy, nothing can replace water—we’re doomed without it.
We read all the time about ways to save water at home, but businesses have an equally important role to play in saving water. Industry, with just simple adjustments, can make a significant improvements in water management.
Check out the following three industries, and the simple strategies that will save water and help protect the planet's most valuable resource:
The hospitality industry:
If hotels, motels and restaurants install only reduced -low shower heads, taps and toilets, millions of liters of water will be saved every year.
The construction industry:
Simply by ensuring that workers clean gutters and other work areas with brooms instead of hosepipes will save significant amounts of water on construction sites across North America and beyond.
The manufacturing industry:
Manufacturing tends to be a thirsty industry. But by identifying ways that water can be used, recycled and used again in other processes, the industry can do much to reduce its water consumption.
Finally, everyone can make a difference by examining their water delivery systems, identifying and repairing leaks.
PVC Plus Drilling Products specialize in the manufacture and distribution of PVC pipes and PVC fittings—the most durable and reliable product for freshwater delivery and wastewater extraction and recycling.
PVC Plus Drilling Products is also a leader in geothermal technology and horizontal and directional drilling. For more information, contact them today.

Manage inventory to keep the wheels turning
Whether you are the inventory manager of a large mining operation in the Middle East, a major construction project here at home or a dealer or manager of a retail outlet, you know that maintaining adequate stock of the products you sell or supply is vital.
But maintaining an adequate supply of inventory can be a difficult task, especially in large operations that use specialized machinery and have a large workforce that relies on multiple products to do their job. It only needs one important component to fail to bring a machine to a standstill, or one product to be out of stock to halt a job or worker.
But by putting in place a few simple strategies, inventory managers can keep projects rolling, machines running and the team at work:
Get everyone on board
Send a memo to every single worker, asking them to inform you if they see certain products are running low or components wearing out. It makes a world of difference when everyone is on the same page.
Simple stock sheets such as this one are popular in the retail sector and are an effective tool for keeping stock of fast-moving products
Identify key components/products
Try to find out the key components that either break often or are difficult to replace and make sure you maintain a good stock of them. Do the same for items that are always in great demand.
PVC Plus Drilling Products are your one-stop shop for all PVC pipe, fittings and drilling-related products.

It’s as simple as HDPE
With North America’s drinking water and sewage infrastructure falling apart, it’s time to take action. But faced with mammoth bills for total replacement of water systems, municipalities consistently plump for cheap short-term repairs for aging and corroding pipes.
HDPE pipe can cure North America’s water woes. Municipalities, provincial, state and federal governments must realize that biting the bullet today and investing in HDPE technology will result in billions of dollars of longterm savings.
HDPE pipe has many benefits, including:
- the ability to create heat-fused joints that are are stronger than the pipe and guaranteed leak free
- heat-fused joints that are self restraining, so restraints or blocks are not required
- superior cold forming to reduce the need for multiple fittings
- the strength to withstand repetitive pressure surges
- it is lighter, cheaper and easier to transport
- superior long-term costs savings
- chemical resistance—HDPE pipe does not corrode
A leading supplier of PVC pipe and fittings, PVC Plus Drilling Products manufacturers slotted PVC pipe screen in horizontal and custom patterns, and distributes Teflon, CPVC, Stainless Steel and HDPE slotted pipes and fittings.

Going Geothermal why the costs are worth it
Geothermal energy might sound like just another “green” fad, born in the wake of Al Gore’s An Inconvenient Truth. But did you know that the first geothermal plant actually opened in Italy in 1911? Clearly, the idea of a heat pump is an oldie and a goodie. If research efforts continue—Google has already invested $11 billion into geothermal drilling research—geothermal energy will be the most viable energy source on the market. There is enough energy in the top 1% of the earth to heat humanity and power our infrastructures for the next 6 billion years!
Geothermal energy is exactly what it sounds like: heat from the earth. But before you read on, note that the first 100 meters below the surface of the earth technically get their heat from the sun. Deeper than 100 meters and geologists are tapping into the 6,000 Celsius core of the earth.
A “ground-source” geothermal heating system relies on geothermal ground loops to bring warm or cool air into the home. These loops, or pipes, contain fluid, which extracts the earth’s heat as it flows through the series of loops all the way to the heat pump inside the home. The geothermal system takes energy from the earth in the winter and transfers it back in the summer—a natural give-and-take cycle that takes advantage of the constant temperature of the earth below your feet.
Upfront, geothermal heating systems are more expensive to install than oil, gas or electrical systems. This is largely because drilling must be added on top of the cost of installment. But in the long-term, it’s worthwhile—for the wealth of your wallet and the health of the planet. You’ll make back the cost premium of your new geothermal unit in as few as 2 to a maximum of 15 years. Savings on maintenance are immense. A staggering 70% of energy used in a geothermal system is renewable. PVC Plus offers all of the geothermal supplies needed to “go geothermal” in style for decades without much fuss.

Newsflash! New rules for geothermal drilling
When purchasing new geothermal supplies, such as drilling fluids, well-drilling supplies and geothermal piping, it is important to investigate the current rules for geothermal drilling. Have regulations about the installing of geothermal energy systems changed? Has new research emerged? Keep your ear to the ground, and stay in the loop (so to speak) so that you have a wider context in which to understand your geothermal energy projects.
As of May 2012, Ontario is tightening the rules regulating the installation and use of vertical closed loop geothermal energy systems. This is unsurprising given the number of geothermal systems installed in the province since 2008: a total of 8,800 geothermal systems.
Vertical, as opposed to ground or water closed loop systems, take up less yard space and have minimal impact on landscaping. Vertical systems are installed by boring holes 200-350 feet deep and then placing the vertical loop into the drill hole. Since it is a closed system, there should not be any contact between the fluid in the system’s pipes and the external environment.
The McGunity government wants to make sure that existing and future geothermal energy systems work safely—in the interests of public safety and well-being.
Other provinces are likely to follow suit in the coming year.
In accordance with the new regulations, geothermal installers need to:
- Acquire provincial permission and approval for new vertical closed loop geothermal systems
- Meet with an engineer or accredited geoscientist before drilling
- Come up with an emergency plan before drilling
Regardless of where you live and what the regulations are, you can rely on PVC Plus Drilling products to help you set up a safe and successful geothermal energy system.

All’s well that ends well
Did you know that the average Quebec citizen uses 350 to 425 litres of water per day on average? Wherever you live, water plays an essential role in your day to day life. And it wouldn’t be possible without the wells we drill and the pipes we install to distribute the water.
From major underground aqueducts, to sewers, to your kitchen sink, more than 90% of Quebecers (and numbers are comparable across urban North America) rely on a municipal water supply. There are three main wells in the province, at Chicoine, St-Adolphe and Xavier. In total, the infrastructure adds up to an incredible 60 km of piping.
Quebec installed its first modern public water system in Montreal in the 1850s using iron and lead pipes. The system grew to include reservoirs, additional wells, and water supply systems in other cities. In the 1960s, Montreal created the province’s first sewage treatment plant.
Iron pipes, however, have not proven to be the most resistant to leaks or breaks; in the last couple of decades, municipal and commercial bodies have been working hard to replace antiquated piping. For example, in 2002 Quebec City launched a major water supply system replacement program, motivated by problems with leakages, which were pulling the plug on the city’s water efficiency. Whether you sit on the Water Works board or develop condominiums, it’s worthwhile to install the sort of piping that maximizes use of our world’s most precious resource.
PVC Plus polyethylene pipes as a more steadfast alternative to iron. It is a highly-durable plastic that should require extremely minimal maintenance over the long term. With equally refined well drilling supplies, well screens and HDPE slotted pipes and fittings, PDC Plus is committed to helping you implement long-lasting water systems.

Pump it up!
Whether you are a professional mining engineer or a homeowner (or both!), it can’t hurt to review the types of geothermal pumps available on the market. New products are constantly being developed so you’ll save time if you know the lay of this ever changing land. Although PVC Plus does offer custom manufacturing of geotechnical screen pipe and pump solutions, this geothermal pump boot camp for your brain will have you flexing those pipes again in no time!
PVC Plus offers a comprehensive range of environmental geothermal pumps. Here is a sampling of them, what they do, and why they’re special.
Made by Waterra, one of PVC Plus’s steadfast suppliers, the Lever Pump was designed to provide you with a convenient, portable mechanism. Tubing and handle combined, it weighs only 7 pounds! Easy to flex your pipes with this system and simply collect samples.
- F&W 6’’ Submersible Pumps
These pumps are often customized, since they are available in a huge range: from 5 to 50 in horsepower. They’re for the heavyweights—best for commercial, municipal, industrial and agricultural applications. Most excitingly, the F&W 6’’ series has new space age thermoplastic impellers, which are the rotating components in these pumps. They bring the energy from the motor to the fluid being pumped—in other words, they are the pumper uppers! And their cutting-edge level of workmanship determines a long-living and maximally efficient system.
The Powerpump 2 is like the Arnold Schwarzenegger of pumps: It is the most powerful pump actuator manufactured by Waterra. A Honda G100, 2.5 horsepower, 4 stroke gasoline motor powers this device!

The Lowdown on the Enbridge Pipeline
News outlets in British Columbia and beyond have been pumping out story after story on the controversial new pipeline proposed by Enbridge Inc. Whether or not you’ve chosen a side already, it helps to have a sense of the facts. At PVC Plus Drilling, we make it our business to stay informed on key issues such as the Northern Gateway Project, because in big and small ways, the energy industry affects all of us.
- Who: Calgary-based Enbridge Inc. The company was founded in 1949 under the name of Interprovincial Pipeline, since the original Enbridge pipeline was built to move oil from Western Canada to eastern refineries. Today, Enbridge runs Canada’s largest energy distribution company and distributes gas to more than 1.9 million people.
- What: The Northern Gateway Project, a proposed $5.5 billion pipeline that would run from Alberta oilsands near Edmonton, to Kitimat on the West Coast of British Columbia. There are two proposed pipelines, one for the westerly flow of oil, the other for the easterly flow of condensate (which is used for thinning petroleum for transport).
- When: The earliest consultations for the Northern Gateway Project began in 2008. Construction is slated to begin in 2013 subject to public and government regulatory review.
- Why: Enbridge and its supporters herald the Northern Gateway pipelines as a great economic benefit to Canada. In a competitive global market, it will provide Canada with access to growing markets in Asia and the West coast of the US. Enbridge further claims that the construction of the pipeline will create thousands of new jobs.
- Why not: Critics of the Enbridge and the Northern Gateway project worry about the risk to the environment, pointing to the company’s record for oil spills (809 spills on Enbridge lines between 1999-2010). Most recently in July 2010, a leaking Enbridge line spilled an estimated 843, 444 gallons of oil into a subsidiary of the Kalamazoo river in southwest Michigan. With more than 50 kilometres of waterways and wetlands affected, and 320 people reporting symptoms from crude oil exposure, it’s not surprising that the cleanup is still ongoing, and ranks as the costliest onshore cleanup in US history at $800 million.
PVC Plus Drilling is a trusted distributor and manufacturer of environmental drilling products, operating out of Montreal, QB since its inception in 2002.

No Longer a Pipe Dream
According to a report published by the Geological Survey of Canada in June 2011, "geothermal energy, as a renewable energy source, not only provides a clean and renewable option for electricity generation around the clock, but also efficient and competitive heating options for Canadians all over Canada."
Online news source Ground Water Canada goes on to summarize the report, saying that Canada has extraordinary resource potential when it comes to geothermal energy.
Geothermal sources could soon replace other energy-extraction methods, which are more invasive, costly and environmentally damaging.
More data still needs to be collected in order to make future projects low-risk and acceptable to industry investors. But geothermal piping companies across the world can attest to an existing market need for their products. There is excitement about geothermal energy brewing all across the world.
Bruce Ritchey, the CEO of Waterfurnace, an American geothermal heating system company, said the following: “Every state should invest in a geothermal incentive. I can't think of a faster, more cost effective, greener way to put people back to work, save fossil fuel, reduce carbon emissions and save homeowners thousands of dollars per year for the next 24 years. It's the stimulus that keeps on stimulating.” (Quoted in Lilith E-Zine).
PVC Plus Drilling began distributing and manufacturing environmental drilling products in March 2002. Residential and commercial interest in geothermal continues to grow and PVC Plus is pleased to be a part of the green movement.

The Things We Carry Part 1
Spotlight on Drilling Fluids
At PVC Plus Drilling, we’re proud to carry some of the best brands available, in addition to our own PVC Plus products such as like geothermal piping. This article is the first in a series that aims to explain the categories of items that we offer. Part 1: What are the different types of drilling muds and polymers? Consider this a refresher course if you’ve been buying drilling fluids for decades. If you’re a newer customer, pay even more close attention.
Drilling fluids, simply put, make drilling easier. They help to manage the pressure in a shaft or well. They are used for oil and natural gas drilling (large scale) and for water well drilling (smaller scale). There are three main types of drilling fluid: gas-based; water-based; and oil-based (sometimes called non-aqueous).
According to the Kirk-Othmer Encyclopedia of Chemical Technology, drilling fluids must be dense enough to “offset formation pressures to prevent a blowout”. In other words, they’re crucial to the drilling process. They lubricate the drill string and keep formation fluids from clogging up the drill bore.
A polymer is a specially-created chemical that is mixed with water to create a particular drilling fluid.
- POLYBORE™ is a water-soluble, dry granular polymer. When mixed with fresh water, the result is a clear drilling fluid that has a stabilizing effect on drilling operations from horizontal directional boring to reverse circulation rotary drilling.
- QUIK-TROL® is a natural cellulosic polymer that provides filtration control in the majority of water-based drilling fluids. It can also be added to vegetable or mineral oil, resulting in an oil-based fluid that can be funneled directly into the drill string.
- DIAMOND SEAL is an interesting product because it is water-swellable but not water-soluble. It is a 100% crystalline synthetic polymer that can absorb hundreds of times its own weight in water. This is important because blowouts are to be avoided, the drilling fluid must be sufficiently dense.

The Things We Carry Part 2
Spotlight on Bentonites
PVC Plus Drilling is proud to carry some of the best brands available, such as Baroid and Quik-Grout.This article is the second in a series that aims to explain the categories of items that we offer, beyond our own PVC Plus products like our geothermal piping or our environmental pumps. Part 2: What are bentonites? How are they used in drilling projects? What sorts of bentonites do we sell?
Bentonite is so named because of its discovery in the 1800s at the Benton Shale geological site in Wyoming. Although many countries in the world now mine and produce bentonite, the world’s top producer is still in the United States, in Wyoming.
Bentonite has an almost magical quality: it swells. Its this attribute that makes it indispensable to drilling endeavors. When bentonite is added to the mixture of things pumped down the drill shaft, it is very helpful because it binds easily to debris and so brings it out.
For most industrial purposes, sodium or calcium bentonite are used but you may also hear of potassium bentonite or aluminum bentonite. Sodium bentonite is excellent because when it’s wet it expands to several times—as much as five times—its dry mass.
- QUIK-GROUT by BAROID is a single-sack sodium-based bentonite intended for as grout for water wells and plugging holes. It does not contain any polymers and it is easy to use.
- HOLEPLUG® graded sodium bentonite is a perfect example of the impressive feats that sodium bentonite is capable of. Hole Plug will fall through a standing column of water in the hole and reach the bottom with delayed hydration without bridging to the wall of the borehole. Let the boring begin!
- BENSEAL® is not recommended as a drilling mud but instead, for sealing and grouting well casings and earthen structures. It is a granular, 8-mesh, natural sodium Bentonite (from Wyoming, of course!).
I bet you didn’t know: sodium bentonites are also used in products as diverse as animal feed, cat litter, colon detoxes and facial cleansers! It truly is the “clay of a thousand uses”.

The Things We Carry Part 3
Spotlight on HDPE
This article is the third in a series that focuses on a particular product or brand that we carry. What is HDPE? Why does PVC Plus offer it? Why should you try it?
High Density Polyethylene (HDPE):
- made from petroleum
- able to withstand very high temperatures
- more opaque than Low Density Polyethylene (LDPE)
- used in everything from hard hats to hula hoops
HDPE Pipe with PVC Plus:
- HDPE Water Pressure Pipes: these can be connected by heating and joining the ends of the pipes together. This is especially useful in situations where digging is hard or impossible to do.
- Pipes and coils: geothermal options using HDPE are highly reliable as well as unsusceptible to leakage. Black HDPE, for instance, is used for natural gas transmission, where it is essential that the leak rate is zero.
Why choose HDPE?
- it’s long-lasting (approaching a 50 year lifespan in some cases)
- it can carry compressed gases, oils, wastes (hazardous and non), slurries, drinkable water, and even cables.
- it has excellent abrasion and damage resistance
- its light weight makes it easy to install
- its properties allow for butt welding (can be heated and seamlessly jointed together)
Please contact us at PVC Plus Drilling Products Inc. if you have any further questions about geothermal piping and HDPE. We are proud to use it and confident in its qualities.

PVC is going to be around for the longterm
Sometimes the rate that technology changes can be simply astonishing, no?
Remember music tape cassettes and video cassettes? Where are they now? Rendered obsolete by the CD and DVD, that’s where.
It’s not that the tape cassette was poor technology, it’s just that as technology in this field continued to advance, new products came on the market that were, faster, simpler...better. And the process never stops.
Since the advent of the USB flash drive, CD sales have plummeted by around 50% since their turn of the millennium peak.
Looking ahead, at the leading edge of technology in other areas, are we about to see the demise of the internal combustion engine—replaced by more efficient battery power?
Maybe, when technology reaches the point where electric cars can travel more than 150 kilometers without having to be recharged. In the meantime, great strides are being taken with existing gasoline and diesel engines to produce more fuel-efficient vehicles.
Considering that PVC pipe production relies on fossil fuels, this is great news for the industry.
PVC pipe has been a game changer since it first arrived on the scene. Light, clean, durable and easy to work with, PVC pipe has transformed the World. From plumbing systems to the rejuvenation of municipal water supplies, PVC has become the ultimate pipe solution. In fact, the future looks bright for PVC pipe to be the number one pipe work solution for generations to come.
PVC Plus Drilling Products is a leading manufacturer and supplier of PVC pipe and PVC fittings for use in applications as diverse as mining, geothermal heating, landfill irrigation and municipal water supplies and sewage treatment and management.

EGS—the future of geothermal energy
With the Worlds ever growing thirst for energy amid the knowledge that our fossil fuels are a dwindling supply, there have been a number of energy solutions that have blossomed oh, so briefly in recent years. But the problem persists—how do you produce mass power at low cost in the same way that oil, gas coal and even water has been in recent years.
Solar and wind power both came on the scene amid considerable fan fare but have not come anywhere near to providing an answer to our energy woes. And nuclear power’s efficiency is outweighed by the fear factor.
Among the known remaining sources of power, that leaves geothermal in the best position—a position that has steadily been growing stronger with the continued development of EGS—enhanced geothermal system.
Prior to the advent of EGS, geothermal heating relied mainly upon tapping into existing heated water systems or the construction of a closed loop of water that could be used for heating and cooling.
But now, EGS is raising the bar by injecteting water at great pressure into hot rock below the earth’s surface. The pressure of injection causes the rock to fracture and allows the water to more easily circulate and capture heat. As with the Alberta oil sands, it is hoped that this technology will become much cheaper over time and EGS will reach its full potential in helping the World satisfy its thirst for power.
PVC Plus Drilling Products Inc. is proud to be at the forefront of the geothermal industry, supplying the PVC pipe and PVC fittings that are essential components of geothermal solutions. For more information, contact PVC Plus Drilling Products today.

Residential septic systems get an unfair rap
This is probably because everyone has heard a nightmare septic-system story—and there’s a definite ick factor associated with visuals of a flooded septic drainage field.
While it’s true that a septic system does have the potential to leak or flood, the truth is that a modern, properly installed and well maintained septic system will prove to be a trouble-free sewage system for a residential or commercial property for many, many years.
The problem with these septic horror stories is that they invariably originate from old and decaying systems that have been poorly maintained or not replaced when due.
The second law of thermodynamics suggests that the tendency for differences in temperature, pressure and chemical potential can combine in a physical entity and lead to the entropic dissolution of the physical entity itself.
In other words...everything is in a gradual state of decay and falling apart.
And that means municipal sewage systems are falling apart, too. And this, in fact, is a key point in the residential septic/municipal sewage discussion. Generally speaking, those who have septic systems installed will ensure that regular maintenance is kept up..after all the alternative may not be very pretty.
On the other hand, paying taxes to allow municipalities to take on the role of sewage maintenance may be hassle free, but that doesn’t mean there aren’t problems. Unfortunately, all older municipalities in the developed world are faced with a crumbling infrastructure riddled with rotting and leaking iron and steel water and wastewater pipes.
Trillions of liters of water are wasted every year. Now that’s food for thought, no?

The answer lies beneath our feet
We might like to feel the sun and wind on our faces, but as far as using these forms of renewable energy to power our World, all is not so rosy—ask China.
Solar panel makers in China are offloading jobs and downgrading shipments as the industry struggles to turn a profit. And a big player in the wind turbine manufacturing industry (also based in China) is sending over 10% of it’s workforce on leave, citing an industry wide slump in sales.
Considering the high investment currently required to set up geothermal energy solutions, you would think that this renewable energy industry would be struggling, too. But in fact, right now the opposite is true.
In East Africa, the Kenya Electricity Generating Company is ramping up geothermal production and aims to reduce its current hydropower output by more than half in the next two years. One of the major reasons offered for this strategy is to get rid of the company’s reliance on the weather.
Once the high initial investment in a geothermal solution has been made up, upkeep is cheap and low maintenance,while the energy source is long lasting with a guaranteed output.
PVC Plus Drilling Products is a proud supporter of the geothermal industry, supplying PVC pipe and PVC fittings. PVC Plus Drilling Products exports World wide to an extensive network of North American distributors, consulting firms, industrial, residential and commercial clients.

Has Geothermal Industry grown in 2012
Geothermal industry has experienced a slow development over the years. However, this industry has been experiencing advanced growth and development over the recent past. According to experts in this industry, different countries have been implementing important measures aimed at popularizing this renewable energy. Despite various challenges experienced in this industry, there have been several positive steps taken by different players in this industry over the recent years. Many experts observe that 2012 has been a year of projects commissions. Places where research has not been done in the past saw emergence of new information on possibility of having new plants established there. Continued realization of potential of various places producing this energy has resulted to more drilling companies
being set up.
Perhaps, it is important to note that despite geothermal industry being one of the industries that have been hit by the recent economic challenges. Many people have turned to this renewable energy as a way of preserving the environment. Continued creation of awareness among energy consumers has resulted to increased number of people using this energy. Over 2012, there have been more projects established to cater for the increasing demand for this energy. Governments and individual investors have also continued to invest in this energy sector. More funds have been channeled to this energy source as a way of developing it. More studies are also being carried out in different parts of the world to find out whether there are more reserves of this energy that are yet to be discovered.
Generally, developments of this energy sector in 2012 are indications of a brighter future when it comes to this energy. Many companies are planning to expand their current geothermal plants
. Others are setting up new plants in new places where they have discovered it. These companies have realized that people are turning on their appliances every now and them. Technology is also making discovery of sources of this energy easier. In addition, more means of exploiting it and advanced facilities are being used in exploiting this energy. Awareness campaigns by environmentalists is also making many people turn to this energy. Individuals and non-governmental environmentalists are sensitizing people on the need for embracing renewable energy such as geothermal increasing its exploitation and usage.

Geothermal Power is it endless
The number of people looking for geothermal accessories has increased rapidly over the recent past. This can be attributed to the increased focus being turned to this form of energy by private investors as well as government agencies. Geothermal power is generated by capturing heat that is stored underground from the core of the earth. In the past, this energy was not recognized like other sources of renewable form of energy such as biomass, solar and wind. However, this energy source can produce dependable and renewable base load of energy.
Currently, there are many parts of the world that have great potential of producing huge amounts of geothermal energy. Basically, chances of realizing increased energy output are very high if various stakeholders invest in this field. More should be done in research as well as development of geothermal plants. Geothermal accessories should also be availed to those who want to invest in this energy. This will help in unlocking more reservoirs that are yet to be exploited. Perhaps, you may be wondering whether geothermal power can be exhausted. Basically, although this power is almost endless, there is the need to manage reservoirs carefully. Proper and careful management of reservoirs is very important in ensuring that underground rocks are not cooled to a level where they cannot supply power.
Although energy investors have not ventured into this field fully, experts predict that more people will invest in this field by the end of the year. There are many geothermal plants that are already under construction while in some places construction is being started. In some places, experts are researching to find out whether there is a probability of exploiting geothermal power. Basically, with increasing concerns about global warming people are turning to renewable forms of energy. This is perhaps, what has resulted to increased focus on geothermal power. Nevertheless, for investors and environmentalists to realize their desired results, geothermal accessories and resources required for research and proper management of reservoirs are available from PVC Plus Drilling Products.

Ins and Outs - Residential Geothermal Installation
A geothermal system is one which uses the constant temperatures below the surface of the earth to cool and heat homes over the long term very economically. It is an environmentally friendly and very inexpensive method for cooling and heating in new housing if your property is a good candidate for it. You can fit older houses with these systems as well, although it can be more of a challenge in older homes.
If you are interested in doing a geothermal installation in your own home, you should first determine if a vertical or horizontal geothermal will be right for you by doing a site evaluation. Having a qualified geothermal technician walk through at this stage of the project to see how much land is available for installation of pipe, what the soil composition is, how deep the bedrock is and what nearby water sources are available. If you live in an area that gets cold, you will need to consider winter temperatures as well, since vertical geothermal is better when the ground will likely freeze.
Your current cooling and heating system needs to be evaluated as well so you know what changes need to be made to accommodate the geothermal fittings
. Steam and other forms of radiant energy generally need to be totally replaced or used as a preheating mechanism for standard cooling and heating which will reduce your savings significantly.
Figure out what geothermal supplies you will need, depending on whether you are using an open loop or a closed loop geothermal system. No fluid leaves or enters in a closed loop system since they are totally sealed. However, an open loop system needs a fresh water source from which it transfers from one spot another.
Depending on the local geology, ditches need to be dug 7-15 feet deep for a horizontal closed-loop system. Then the heat exchange PVC piping is laid into the ditches. For a closed vertical system you’ll need to dig holes that are 150 to 300 feet in depth. Then install hairpin geothermal pipe that is rated for your system. Around 1000 to 1500 feet of pipes are needed to cool or heat an average home adequately. For a slinky coil closed system, a wide trench needs to be dug where you will install looping pipes. A pond loop geothermal systems needs a trench dug to the local body of water and then loop coils installed on the bottom of the pond. The pond has to be at least ¼ acre in size.
So expect to do a lot of digging! Successful geothermal installations require good planning, quality materials, and a team of qualified people to help. Check out PVC Plus Drillings quality supplies

Mineral Exploration is on the Rise in Nth America
Global interest in Canadian metals and minerals hit a record high in 2011, with investment in exploration reaching a staggering figure of US $3.9 billion. Exploration spending rose by 585% in the period of 2002-2011, enabling Canada to become a global destination of choice for mineral exploration in 2011. There can be no doubt about it. Mineral exploration is booming in North America and particularly in Canada.
The value of mineral production in Canada rose around 21% in 2011 to $50.3 billion driven by price increases of minerals. The leading mining provinces in the country that rule in terms of mineral production include Ontario at $10.6 billion, Saskatchewan at $9.2 billion, British Columbia at $8.5 billion, and Quebec at $7.7 billion. In total, the mining industry contributed $35.6 billion to the national Gross Domestic Product. At the same time, it paid more than $9 billion in royalties and taxes to Canadian governments. The industry also employed 320,000 workers across the country.
Since there is an intrinsic link between mineral production and exploration activity, we could witness a dramatic expansion of the Canadian mining industry in the coming years. In order to take advantage of the opportunities that the future holds for the industry, it is, however, important to make sure that there is access to the right regulatory and investment environments that are imperative for supporting development. For instance, mineral exploration products
have to be in adequate supply so that exploration activity does not suffer any unnecessary delays or setbacks.
The rapidly growing industry does face some challenges, one of which is reduced capital access for some miners. Despite these challenges, the economic prospects of the Canadian mining industry can be said to be quite strong. Though the rate of growth in China and other rising markets can be a cause of concern, Canada’s growth is expected to remain strong even if it is at a somewhat slower pace. In fact, the situation in Canada is much less time-consuming and less burdensome than the scenario currently playing out in the United States.

Will California lead the next Oil Boom
Like most states in the United States, California is experiencing financial troubles and the state’s consumers are struggling to put food on the table. However, unlike the other states, California has a vast untapped oil reserve that can help both the state and its citizens. With proper well drilling supplies and drilling fluids, California may be able to realize a significant influx of cash.
California’s democratic governor, Jerry Brown, and his administration aren’t sold on the idea of drilling for shale oil deposits because of environmental concerns. Not long ago the state of North Dakota faced a similar challenge that worked out well for the state, bringing in millions of dollars for the state’s coffers.
At issue is the 1,700 square-mile Monterey Shale which is located on California’s central coast adjacent to the San Joaquin Valley. The area holds about 60% of the country’s estimated shale oil reserves, and with high-tech well drilling supplies it could potentially help California get out of trouble. California remains one of the country’s top oil producers along with North Dakota, Alaska and Texas. In fact, it is the fourth-largest oil producer in the nation even though oil production has declined significantly since the mid-1980s.
One of the reasons the governor is hesitant about allowing drilling is because the state’s economy is showing signs of improvement. The state’s downward slide was caused by a set of regulations that effectively limited the ability of major corporations to produce oil in the region. Many of these corporations have threatened to leave the state entirely because of its multi-billion dollar budget deficits and high unemployment rate.
In an effort to help California get back on its feet, Governor Brown raised income taxes on the state’s highest earners which are the same group of people that are providing jobs. The state’s highest earners are also responsible for paying the most taxes.
Energy consultant Geoffrey Styles recently published a piece on the online forum ‘The Energy Collective’ outlining how, with the right well drilling supplies, the shale formation has the potential to add billions of dollars a year to the local economy and produce lots of good jobs.
Oil production in the region is still in the developmental stages and oil companies are working hard to overcome the areas complex structure. Only new technologically advanced well drilling supplies and drilling fluids can help engineers overcome the challenges, and possibly get the governor on board.

Why Use Slotted Collection Systems
Advances in technology have made geothermal energy an increasingly credible alternative to power derived from conventional fuels. The environmental impact of fossil fuel use is one of the considerations driving research into geothermal technology. In addition, rising energy prices and dwindling fossil fuel reserves have created a dire economic need for alternatives.
Locating a site for a geothermal energy installation is complex. A number of requirements must be met: chiefly, the presence of sufficient geothermal fluid (water, vapor or gas) and a reservoir of heat that won't quickly become exhausted. Among other approaches, mineral exploration techniques can be used to assess the viability of a potential geothermal site.
Setting up a geothermal installation requires a range of specialized materials and equipment. Drilling equipment and other supplies such as drilling fluids
are only the beginning. To make use of the heat trapped below the earth's crust, it's necessary to drill down into the ground — often for a considerable depth. The structural stability of geothermal boreholes must be maintained. This requires well screens, risers and other geothermal fittings
A geothermal well requires long-term stability to remain productive. To provide stability for a borehole, well liners are generally used. These help to support the material forming the sides of the borehole and preventing it from collapsing. Well liners also keep larger pieces of rock or debris from falling into the borehole, preventing it from becoming blocked. They can be made out of various materials.
A reliable alternative to using metal screens is the use of well screens manufactured from polymers (plastics). Pipes and tubes made from plastics such as High Density Polyethylene (HDPE) and Polyvinyl Chloride (PVC) are inexpensive, durable and widely available. Standard pipes are perforated with round holes, which in some cases can be blocked by debris. Round or angular pieces of gravel or fragments of backfill can become lodged in the holes, occluding much of their area. If a significant number of holes become blocked, this has the effects of diminishing the ability of the pipe to collect. To solve this problem, pipes with slot-shaped holes can be used. Because of the shape of the hole, it's much less likely that the entire slot will become blocked.
PVC Plus provides a range of quality slotted collection systems, both in PVC and HDPE. These products are manufactured to a high standard from top-grade materials, ensuring excellent performance and longevity. The PVC Plus range is a cost-effective and reliable solution to all of your geothermal drilling, geotechnical and mineral exploration needs.

Steel Well Screens and Risers—Geothermal Projects
Instead of burning fossil fuels, geothermal installations use heat from below the earth's crust. Water or vapor heated by pockets of magma and hot rocks is pumped to the surface via boreholes. This is then used to generate electricity or as a source of warmth for heating.
Specialist companies exist to furnish geothermal fittings to the installation team, along with the other materials and equipment they need to set up reliable sources of geothermal energy. PVC Plus is one company that offers a wide range of drilling fluids
and geothermal fittings
To ensure that a geothermal installation remains productive, the boreholes through which the warm water flows must remain stable. To keep them open and unblocked, they can be lined with well screens. Risers are fitted to allow water to flow freely from boreholes and on into the rest of the geothermal system.
Metal is often used to make well screens and risers, generally in the form of steel mesh. This kind of screen has some drawbacks, however; it is somewhat more expensive than other materials and in some cases can be prone to corrosion. To avoid problems with a geothermal collection system, it's important to choose materials that won't rust or deteriorate even after long periods of contact with flowing water.
One way to avoid this issue is to choose products that are made from high-quality stainless steel. Buying from a reputable supplier such as PVC Plus Drilling helps ensure that all the materials used are durable and reliable. We offer a range of products for geothermal drilling, including steel risers and well screens. Our stainless steel products feature a wire wrapped construction and are corrosion resistant. They are individually wrapped before being hot-water washed and then air-dried. PVC Plus risers and well screens are a cost-effective solution for well installations of less than one hundred feet in depth.

A Closer Look at Geothermal Energy
Recent and steady hikes in oil prices have driven many companies to give renewable energy sources a serious thought! In a world where climate changes are a big concern, and with a growing population whose energy demands are going through the roof, the supply of energy needs a boost while still being gentle to the earth. Geothermal energy is a smart and sustainable energy alternative along with solar, wind and hydropower.
In the race to curb global warming, many manufacturers of renewable-energy related supplies and products are popping up. Finding a trusted and reliable company, who can supply geothermal energy harnessing tools and accessories, thus enabling geothermal power companies to operate at their optimum is very important. PVC Plus is a trailblazer company when it comes to achieving progress through innovation, and their geothermal supplies
, as well as geothermal fittings
, are top notch!
Now, it wouldn't be true to brand geothermal energy as a new "trend" as it has been around for years. However, it is absolutely right to deem the current technology as trendy! With the improved geothermal power harnessing technology and continued research, geothermal energy has picked up pace and is becoming more reliable. With developments in performance enhancing pipes and coils, like the cutting edge Geocoils (U-Bends Coils), that reduce damage risks without jeopardizing harnessing capacity, geothermal installations are becoming more and more advanced. Other products such as geothermal grouts allow for better handling of thermal conductivity.
Well drilling technology largely dictates safety and productivity of any geothermal energy undertaking. With the availability of innovative well drilling supplies, efficiency is being achieved with minimal manpower wastage, which enables companies to reduce harnessing costs without compromising safety. Drilling fluids play a central role in curbing the risks of corrosion as well as providing hydrostatic pressure. PVC PLUS carries drilling fluids and well drilling supplies
that promote harnessing safety.

Installing a Geothermal Loop System
For householders looking to make a long term investment in harnessing geothermal power for their domestic use, perhaps the most popular method is to look into installing a geothermal loop system. However as appealing as 'free' energy may appear, it's crucial that the installer pays close attention to how they install their apparatus, and is aware of the regulations in place.
As geothermal technology
has become more efficient and prominent on the market, it's key to ensure that a quality contractor is hired to carry out the installation. A qualified - and certified - expert ought to protect against the risk of mistakes that can work out to be very expensive to rectify, and even for the most ambitious homeowner it's important to at the very least discuss plans with a consultant.
A good installer should be able to install a fully efficient geothermal loop within a couple of days, usually split between excavating soil, installing the loops and then landscaping the earth back over. Once more, a quality contractor will ensure that the appropriate depth is reached - with the Canadian Standards Association (Standard 448) suggesting a minimum of four feet - and ideally a little more to reach maximum efficiency. Expertise, and the right equipment can pay dividends here as frequently heavy, rocky earth will need powerful lifting machinery, that is far better to have contacted for rather than discover after a couple of feet that expensive plant is going to need to be hired.
Thermal stability generally increases with depth. That needs to be carefully measured in order to ensure that the works will comply with local regulations. A number of provinces insist upon the use of trench scaffolding for depths over six feet, important to ensure a stable excavation, but a style of digging that will invariably add considerably to the overall expense of the project. The reasons for this are primarily founded upon site safety, but also that any project involving extensive excavation can have a destabilizing influence over nearby properties and constructions that may not be apparent at the first instance but can have a gradual destabilizing effect over time.
For those considering a sheer, vertical installation of their geothermal pipe
, the regulations are less porous but care still needs to be had. The average vertical borehole will be up to 200 feet in depth, an advantage for those only considering installing a couple of units however given their depth they must be installed further apart than shallower alternatives. Trenches are usually spaced at around 10 feet apart to maximize efficiency, whereas boreholes, depending on depth, will require up to 15.
Taking care when undertaking these projects should ensure that a fine geothermal supply can be sourced from well installed trenches or boreholes, however it's equally crucial to ensure that the pipes will be well below the realistic depth that frost will be able to penetrate; yet also shallow enough to ensure construction delivers fair value. Installing geothermal pipes is essentially a careful balancing act, and for a project with great long term benefits it pays to consult before construction.

The Challenges of Mineral Exploration in NA
There is no doubt that mineral exploration
in North America is at an all time high, and is set to increase in the near future. Most analysts will agree that the recently discovered mineral deposits of various metals and much-needed chemicals in different industries, has attracted billions of dollars in investments. In fact, amongst all the North American countries, Canada is increasingly becoming a favorite mining destination due to its immense deposits of oil, metals, and other minerals that are in high demand in many industries. However, despite the great advances in the mining industry as well as growing demand for mineral products, it is a fact that mineral exploration in North America still faces challenges that cannot be ignored.
Even with the large deposits of minerals, there is still the controversial question of getting the favorable legislation to mine the minerals at economically viable rates. It is not a secret anymore that many mineral companies spend a lot of resources on lobbying just to ensure that their mining activities are not hampered by anti-mining entities that threaten to shut them down. There are many environmental groups and organizations that campaign heavily to stop further mineral exploration and mining activities in the interest of protecting an already delicate and imbalanced ecosystem. While they can bring valid points to consider, it is a fact that when mineral exploration and mining activities are well managed, the environment need not suffer any harm, and many people's lives can actually be enhanced by these mining activities.
The guarantee of certain targeted prices in the market after mineral exploration
and mining activities is also a great challenge to many mining companies. It is true that mineral exploration usually takes a lot of time, and huge capital investments; that has to be borrowed from commercial banks or even governments. While the cost of borrowing may be economically viable, the guarantee of selling the minerals at target prices may pose a huge and hard-to-manage risk to the mineral companies. It is a fact that predicting the direction of prices in the market and hedging against similar risks is a skill in itself, and companies usually end up paying top dollar for talented individuals in the realm of financial and economic management.
Some mining companies opt to include energy futures as a hedging strategy as well as a means to make more money for their products. Others use a variety of innovative financial tools to achieve the same result. It is true that controlling the cost of mineral extraction is also critical to the success of the business. Using up-to-date drilling products and cost-effective drilling fluids can save the company huge sums of money in the long run. PVC Plus products offer great solutions at cost effective prices.

Safe Handling and Disposal of Well-Wastewaters
Mineral exploration and development continues to expand and develop into new territories using new technologies as well as tried and true practices. One of the most common practices is hydraulic fracturing or “fracking.” Although it is highly successful in extracting elements contained deep within the earth, fracking comes with inherent risks to the environment and moreover our water supply. Plenty of opposition exists where fracking projects take place or are set to begin.
The adding of drilling fluids
is required to ensure that the process runs smoothly and successfully. Without the adding of these drilling fluids, wells can collapse in upon themselves, become jammed, or not produce. So what exactly can be done to preserve our water tables from the risks associated with fracking?
Huge volumes of water are required at the onset of a fracking project. Starting by drawing up the quantities needed from the local water table is often how a project will start. But rather than depleting a local water source, companies could re-use wastewaters from previous sites or have water trucked in from other sources. One of the major objections to fracking stems from this very issue of depleting the local water table to the point of harming farmlands and natural habitat.
Adding of drilling fluids. Once the water needed is pumped up or delivered to the well site, the water is combined with chemical additivesand what’s called proppant to make the hydraulic fracturing (HF) drilling fluid. It is at this stage that the water becomes volatile in terms of its toxicity. The chemicals added are highly toxic and contain various combinations of chemicals designed to aid in the extraction of resources. If leaked into the environment, these additives are a major safety concern.
The main danger is the release of these toxins into the local surface and ground water through on-site spills and/or leaks, and furthermore, as the water travels, into rivers, lakes, and oceans. These risks can be minimized through on-site precautions, careful and attentive workers, as well as choosing the least-harmful additives.
Safe handling of wastewater.
Wastewater can be dealt with in several ways. One commonly used method of disposal is through underground injection. Basically what happens with this method is the wastewater is pumped back down into underground cavities and sealed up with a plug. The danger here is the possibility of the wastewater leaching or leaking into the water table as time passes.
Another method is the treatment of wastewaters, followed by disposing it into surface water bodies. The danger here is the by-products produced when treating waste waters, and contaminants reaching drinking water due to surface water discharge or inadequate treatment.
And lastly, the practice of recycling wastewaters in other hydraulic fracturing projects is ideal because of the amounts of water required, as well as not releasing contaminated water into the environment.

Renewable Global Energy Production
Renewable energy sources on the rise
Renewable energy is predicted to exceed gas and nuclear energy sources by 2016. Whoa. That’s not that far away! Quoting from the International Energy Agency’s (IEA) annual Medium-Term Renewable Energy Market Report; “Power generation from hydro, wind, solar and other renewable sources worldwide will exceed that from gas and be twice that from nuclear by 2016.”
That’s a pretty major prediction when you stop and think about it. With ever growing concern and demand for finding, developing and practicing renewable and sustainable practices for all aspects of daily life, this comes as a big boost to those in the trenches of environmental awareness. Renewable energy
is the fastest growing power-generating sector and makes up to one quarter of the world wide power mix. It is expected that non-hydro power sources will double in numbers by 2018.
Driving demand for renewable energy
There are two key factors behind the increasing demand for renewable energies such as geothermal
and solar. The first factor is that investment and consumption are increasing rapidly in up-and-coming markets. In these markets in particular, renewable energy can quickly and efficiently address power supply, diversification needs and pollution concerns. Europe and the USA lead the way in this area.
The second factor is that renewable energy is quickly becoming more cost-competitive. That means that renewable energy is beginning to be able to compete with gas power or hydro-electric sources and enables them to be a real consideration and an efficient piece of the energy puzzle.
Are we underestimating the power of renewables?
Founder and director, Daniel Kammen, of the Renewable and Appropriate Energy Laboratory at the University of California, Berkeley states that the IEA’s predictions are conservative. Perhaps we are underestimating the potential and power of these renewable energy sources?
Barak Obama eluded in a speech that the impact to human health is great and far reaching when it comes to global warming and the effort to minimize and curb these factors is of high priorty. Factors that impact human health related to energy sources include:
- Heat waves
- Earthquakes, fires, famines and floods
- Extreme weather
- Rise in asthma and respiratory problems
- Rise in mosquito borne illness
- Water contamination
- Poor nutrition due to agricultural impacts

Reaching the Unreachable—Well Drilling with Buoys
Oil and Gas Well Drilling Exploration
Oil and gas exploration initiatives have uncovered a wealth of untapped resources, both on-land and offshore. Offshore drilling provides huge amounts of crude oil—1.5 million barrels each day from offshore drilling, by the United States alone! It is estimated that one-third of the world’s total supply of oil comes from offshore sources.
The Offshore Challenge
Because these offshore wells require a fixed platform from which to drill from, offshore drilling poses its own limits and drawbacks. Just reaching the ocean floor is a challenge, as many times it is half a mile or more below the surface of the water. These variables have set limits on developing many potential oil reserves.
Oil and gas exploration companies have long desired to capitalize on what’s known as “stranded oil reserves.” Stranded oil reserves are reserves of oil located in areas labeled uneconomical for development and recovery using our current drilling technology
. Areas can be uneconomical for a variety of reasons, such as:
- Unstable environment—sea-beds, drilling location, or the ocean itself
- Drilling equipment—un-adaptable well drilling supplies and equipment
- Inadequate advances in our drilling technology—we’re just not there yet!
- Proper well drilling supplies are not developed for specific situations
Mobilizing New Well Drilling Technology
A new and exciting idea that is being developed by an engineering firm (ABTechnology) is called “Advanced Buoy Technology.”
Together in partnership with Enegi, they hope to develop assets in the North Sea. This technology basically makes use of a floating buoy to extract gas and oil from undersea sources. It hopes to capitalize on untapped resources that are too small for big rigs to profit from.
Because it uses newer and smaller technology as well as mobile vessels, storage tanks and equipment; in theory it would be easy to move from location to location. It is believed that this system could be used to develop oil fields containing between 10 and 30 million barrels of oil. The system is un-manned and sits just below the water’s surface. It contains equipment to produce and process the oil as well as a storage facility. From the storage facility, a tanker would be required to periodically take away the oil.
“The beauty of the buoy, of course, is that it can be removed very easily; it can be moved to other locations. It’s got a 20-year life and it can be used on two, three, maybe even four projects,” ENegi CEO Alan Minty said. “So it’s a very, very flexible approach, although we recognize that it’s not a panacea for all marginal fields.”
According to Enegi and Wood Mackenzie, there are an estimated 287 discovered oil fields in the UK’s North Sea that contain 2.2 billion barrels of oil and 9 trillion cubic feet of gas. Well drilling
in these areas could not only be profitable, it could open the door for further discoveries and recovery of oil reserves. Alan Minty further states:
"We've trawled through several databases and we've identified slightly under 600 marginal fields that are suitable for this technology, with about a third of those in the North Sea."
That’s a lot of potentially profitable well drilling
sites and oil resources that would become recoverable with this offshore new well drilling system.

Transition to Renewable Energies—the Debate Heats
The debate heats up
As the ever increasing quest for energy heats up worldwide, two filmmakers have joined the debate. Josh Fox, a liberal environmental activist and Phelim McAleer, a free-market conservative, have picked up two very different and opposing stances on the fracking debate. Apparently, the two don’t see eye to eye on this subject, and little else; especially each other.
Documenteries shine the light on both sides
The pair has created two documentaries: the sequel to Fox’s “Gasland,” which hit the air July 8, and McALeer’s “FrackNation” which took to the air the next night, July 9. Both films have very clear opinions about hydraulic fracturing, or “fracking.” Fracking is a controversial system of well drilling
that uses controversial drilling fluids
. While experts from both sides of the fracking debate say each side has some good points, and legit facts; the filmmakers themselves hold to the claim that the other is distorting fact, or ignoring benefits.
Making the switch
Either way, with the incredible need to phase ourselves off of carbon-heavy energies and start switching to renewable energies, is not an instant solution. Barak Obama has backed the idea of using natural gas as a “bridge” fuel because it emits half the carbon dioxide that coal does.
So what do we switch to? Renewable energies abound, and all rely on harnessing natural and sustainable energy sources such as wind, sun, earth, and water power. The earth itself generates an incredible amount of energy, which can be safely and efficiently harnessed using geothermal technology. Geothermal supplies
and technologies have come a long way in their quality; and their cost is comparable to other renewable alternatives.
Geothermal energy is on the rise in North America as home and business owners search for better energy alternatives. A geothermal system involves installing geothermal loops underground that capture the temperature of the earth; this is then pumped through a system filled with water to heat and cool buildings, depending on the seasons. A geothermal installation can be tailored to your specific needs and scaled up or down depending on the demands of each project. Using quality geothermal supplies will ensure that your project is not only efficient, but that it will require less maintenance and repair in the future.

Ensuring Groundwater Safety—Aquifers and Drilling
Ensuring that our water supply remains untainted and at appropriate levels is essential to our generation and those to come. If industrialized business, farming, oil and gas exploration, and other industries are not managed properly, our water supply is directly threatened. Finding sustainable practices and using quality well drilling supplies
is key to these industries and our environment, and must also be regulated and backed by both our governments and the people.
Finding and practicing safe methods of production and extraction of our resources is not only essential to profitability, it will also play a big role in how long these industries will carry on throughout the years to come. When talking about the impact on groundwater specifically, there are a few things to make note of:
Water never sits still.
Water is continuously on the move. It never sits in one place permanently. Whether it evaporates or is channeled through rivers and streams, or underground; it is constantly undergoing transformation and transportation. The basic water cycle is as follows:
- Precipitation (water) falls
- Run-off occurs as water travels through above and below-ground waterways
- Water consumed by plants is released via transpiration
- Water evaporates from ground water sources like rivers and lakes, or oceans
- Evaporated/transpirated water forms clouds (condensation)
- Condensation falls as rain/precipitation, and the cycle repeats
Aquifers and Aquitards
An aquifer is a porous formation that acts similarly to a sponge. It holds and will produce water when drilled and pumped. Common types of aquifer are sands and gravel. They are recognizable by their relatively large pockets in between the rock particle that allow for the absorption of water and other liquids. There are three main types of aquifer:
- Unconfined aquifers—these are porous aquifer who’s top layer is also the water table
- Confined aquifer—the porous aquifer formation is located below a non-porous aquitard
- Semi-confined—also known as a leaky aquifer, these are partially surrounded by aquitards with some permeability
The shallowest, unconfined aquifers are obviously the easiest to access, and also the ones most susceptible to pollution. The deeper you go, the more confined and semi-confined aquifers you will find. When an aquifer is found at great depths, and the surrounding materials are aquitards, the more secure it is from contamination.
So in regards to groundwater safety, determining the safest method and location to dispose of wastewaters from drilling projects, or when sourcing water for a well drilling operation
; it is critical to keep in mind the makeup of the aquifers in order to make a sound judgement.

Study Suggests Chemicals did not Contaminate Water
In Pittsburgh, a federal hydraulic fracturing (fracking) study that was recently completed suggests that there is no viable evidence to support the claim that fracking contaminated the drinking water aquifers at a western Pennsylvania drilling site.
In Depth Research Project Provides Valuable Information
After monitoring the site in question for one whole year, researchers reported that the drilling fluids containing toxic elements remained far below the water table, several thousand feet lower in fact. The study is on-going, and controversial of course, as opponents of fracking are less than convinced at the merit of this study.
Fracking is fraught with controversy and polarized positions. Environmentalists stand firm on the grounds that it is dangerous and potentially disastrous for our planet’s water sources. Oil and gas companies rely on fracking to reach deep down into untapped oil and gas reserves, and remain steadfastly certain that the economic benefits of fracking far outweigh the dangers.
One valid point made is that the researchers conducting the site may have done the study with much higher standards than that maintained at your average drilling site. This fact points to the need for increased well site monitoring and enforcing of higher standards for drilling sites. Fracking is a hugely popular method for reaching otherwise unreachable gas reserves deep within the earth, so it is imperative that a set of standards is set high and followed.
Fracking Side Effects
The effects of fracking could vary greatly, depending on the location of the drill site. Different types of rock and other factors could create very different reactions and potentially adverse effects. When fracking in more fragile rock formation, the fractures could potential reach much further than anticipated, and if not properly monitored and measured, reach into water tables. That being said, it is largely avoidable when due care and proper time is taken to assess the drill site’s progress.
Solution Based Outlook
Rather than creating controversy for the sake of controversy, approaching the entire topic with a can-do attitude that is focused on finding and making realistic and effective solutions will greatly benefit everybody, especially the local people who find these fracking sites in their backyards. That must remain the priority. Safety for families and communities is of far greater value than creating economic prosperity at any cost.
Well drilling procedures can be established that would greatly minimize any potential dangers associated with fracking. Well drilling equipment and well drilling fluids can also be engineered with safety and environmental sensitivity in mind. Using and re-using water supplies in the fracking procedures will also cut down the negative effects that this method can potentially have.
