Introduction Hydraulic Fracking is a big epidemic in South Africa, Karoo. The Karoo is at risk of contamination of ground water and in possible danger of losing its indigenous ecosystem. The effects of fracking are not only detrimental to the environment but also to the communities around the Karoo. Due to Fracking the air, water and agricultural land are polluted and contaminated and all these factors have a direct impact on the people around the Karoo area and other South African provinces. What is Hydraulic Fracking? Hydraulic Fracking “Hydro-fracking” is a controversial technique on extracting oil and shale gas from the Earth’s surface. This technique was developed in the late 1940’s to access fossil energy by drilling down the Earth. The process of Hydrofracking is explicit due to the controversial manner in which it is done. Vertical well bores are drilled thousands of metres into the earth, through sediment layers, the water table, and shale rock formations in order to reach the oil and gas. The drilling is then angled horizontally, where a cement casing is installed and will serve as a pipe for the large volumes of water, fracking fluid, chemicals and sand needed to fracture the rock and shale. In some cases, prior to the injection of fluids, small explosions are used to open up the rock layers. The fractures allow the gas and oil to be removed from the formerly impermeable rock. The breaking of the resistant rock may result in minor Earthquakes. Due to the
Hydraulic fracturing is also known as “fracking” is a technique which involves drilling down, then horizontally as far as 10,000 feet below the surface to release natural gasses stored in the sedimentary rock known as Shale. The channel is then encased with concrete or occasionally steel to allow millions of gallons of water to be injected into the wellbore. Most water used in fracking comes from surface water sources such as rivers, lakes, or other accessible bodies of water nearby. Not only is there water being funneled into the wellbore, but also a mixture of sand and other chemicals. When the high-pressure mixture is injected underground it fractures the Shale around the wellbore and creates fissures. The fissures are then held open with
Hydraulic fracturing, better known as fracking, is the process of removing oil and natural gas from in between layers of shale and other low-permeability rocks. This is done by drilling both a well and a horizontal tunnel. Sand and chemicals are shot through the tunnel with incredible pressure, which cracks the shale allowing the oil and natural gas to travel up the well (Jackson, 2014). Fracking has caused a breadth of controversy due to the economic benefits and the geological consequences.
“Fracking is the process of obtaining Natural Gas from below Earth’s surface by drilling 1000’s of feet into the earth before a high-pressure water mixture is directed at the rock to release the gas inside.” Water, sand and chemicals are injected into the rock at high pressure which allows the gas to flow out to the head of the well.” (Jackson). Hydraulic Fracturing got its name due to the fact of how the rock is fractured apart by the high pressure mixture of a number of chemicals, sand, and water. Drilling companies first began Fracking in the early 1940’s, and starting in the 1990’s companies began “safer drilling” due to the amount of concerns that had arisen because early drillers had to detonate small explosions that eventually ended up killing many people. Fracking has been used for nearly 60 years and the number of concerns about it are rising every day. Due to the new technological advancements in drilling Fracking has changed greatly over the years. Before, the drilling would go on for weeks on end in order to extract only a small amount of natural gas. Now, due to the invention of higher powered drills, the drills get double the amount then they used to be able to get in more then half the time. Over 95,000 square miles of shale deposits have been found around the Appalachian Basin but the only way to reach these deposits of shale is through fracking. “Fracking is a technique designed to recover gas and oil from shale rock by drilling
Hydraulic fracturing also called fracking has been around for many years despite the recent events of controversy to continue fracturing or not. With the earth’s resources depleting rapidly every year and no sufficient replacement for energy humanity needs fracking. The process of fracking has been around for more than six decades. Fracking has been around since the 1940s and was created to increase the removal flow of oil and natural gas. In the words of chemical engineer Robert Rapier “Fracking involves pumping water, chemicals, and a proppant down an oil or gas well under high pressure to break open channels in the rock holding the oil or gas (Rapier).” A proppant can be different materials,
Fracking is a shorter form of Hydraulic Fracturing which is the extraction process of both natural gas and oil. The process involves drilling deep into the Earth’s surface. Fractures are then created by “pumping large quantities of fluids at high pressure down a welfare and into the target rock formation” (EPA, 2016). After making these openings for the gas or oil to come up (known as “flowback”) the materials can be stored. The reason the fracking process occurs is because “more usual methods of extraction may not be able to fully reach the deposits of shale gas and oil” (2015).
With the age of constant industrial and technological growth has come the necessity for not only cost effective and efficient methods for industry, but also the need for obtaining fuel for the machines that make the modern world possible. Oil has become as precious a commodity as gold, if not more so; its attainments constantly driving the world's largest businesses and governments across the world into action. Naturally, a "quick-fix" solution to this problem is constantly sought after by oil companies wishing to provide oil on a massive scale. One of these drilling methods is known as induced hydraulic fracturing (also known as fracking).
As explained earlier fracking or hydraulic fracking is the extraction of natural gasses from shell rock deep beneath the earth’s surface. Fracking makes it possible to extract and produce natural gases that were once unreachable with other
Fracking is a mining approach in which a well in drilled thousands of feet deep into the Earth for the express purpose of gathering oil and gas from fuel reserves deep within its crust. Essentially, drill teams pierce through the planets sediment layers, water table and shale rock formations before placing a casing of cement as a sort of access valve to the raw fuel. This casing also acts as a channel for colossal amounts of water, sand and 50,000 gallons of fracking fluid used to extract the fuel from its location in the Earth. Fracking fluid, an unregulated chemical cocktail consisting of Naphthenic Acidethoxylate or Poly (Oxy-`1,2-Ethanediyl), Alpha-(4-Nonylphenyl)- Omega-Hydroxy-, Branched and other undisclosed chemicals, is maybe the most controversial element of the fracking process. When these fluids are dispensed into a well, a plethora of chemical reactions occur allowing oil and gas to be separated from shale in the earth and collected in its raw forms, before being transported to facilities for refining. In many instances, explosives such as TNT are set off before these solutions are poured as a means of rupturing and clearing bedrock.
Fracking refers to the process of drilling into the earth, which is commonly referred to as hydraulic fracturing. This injection of water, sand, and chemicals especially in shale deposits releases oil or gas that has been trapped for many years that was initiated many years ago for the purpose of oil and gas extraction from the earth (Anderson and Bosselmann, 2013). The process can be carried out both vertically or horizontally such that it creates new pathways or extend already existing ones. The process causes a lot of controversy and at the same time, it acts as a potential key that will someday in the future unlock greater sources of energy (Bamberger and Oswald, 2014). This research therefore seeks to look at the positive aspects of the
The global crisis surrounding energy needs grows in severity as time goes by and in order to solve it, scientists have created the innovative solution known as hydraulic fracturing (Source 5). Hydraulic fracturing, commonly referred to as “fracking,” is a process that injects water, chemicals, sand, and other materials into layers of shale. The injected mixture cracks the layers of shale, releasing trapped natural gasses that can be collected (Source 1). Fracking occurs deep under the surface of the earth, miles below the groundwater that is accessed from drinking-water wells. In the mid-2000s, “fuel prices were rising rapidly” (Source 5). Hydraulic fracturing was a cheap solution that not only brought the world out of a state of emergency but made oil prices drop. The new method of gas collection grew the oil and gas industry, benefiting people all around the world. Fracking is a cheap, effective solution to global needs, but is under attack from skeptics who worry about environmental hazards. The claims against fracking not only have no real evidence but also risk destroying the jobs in the oil and gas industry as well as support for energy needs. Hydraulic fracturing is not only a cheap but a safe method that supports global needs surrounding both energy and jobs.
Hydraulic fracturing is a process of collecting natural gas by pressurizing shale beds. Fracking consists of two components: a drill and fracturing fluids [4]. Well shafts are drilled into a bed of shale less than two thousand feet deep to form a horizontal fracture because less force is required to make the rock strata buckle perpendicularly to the drill [2]. After the primary shaft has been drilled, cement is poured into the surrounding area to keep the fracturing fluids from backtracking up the shaft [2]. Once the drill is placed into the pay zone, where the reservoir of oil is located, fracturing fluids are forced into the surrounding
Hydraulic fracturing, also known as fracking, is the process of drilling wells thousands of feet below the Earth’s surface to extract natural gas deposits that are trapped in shale layers. Large amounts of a solution containing water, sand, and chemicals are shot down the well to fracture the shale layers, thus releasing the desired product. Natural gas is seen as a potential solution to the energy dilemma that faces the world today. However, the process of fracking and the advantages and disadvantages it poses to the environment are heavily debated. In order to gather a real idea of viability of fracking, all issues must be taken in to account and the subject must be looked at from multiple perspectives.
Hydraulic fracking is a process in which metal pipes are first drilled vertically thousands of feet deep into the ground and then further drilled horizontally in order to maximize the drilling of several wells from one drilling pad. Meaning, there is more efficiency through horizontal drilling because shale which is the horizontal layer where natural gas is found, is found at certain rock layers rather than being abundant randomly. This would defeat the purpose of constantly drilling vertically and waste money and time, therefore, the technique of horizontal drilling is efficient to the extraction process. Furthermore, this method uses millions of gallons of water and chemicals which are injected down a pipe, thus causing the shale rock layer to break. As a result, due to a difference in pressure the natural
Fracking, also known as hydraulic fracturing involves the extraction of natural gas from deep below the ground. A shaft is drilled into the ground followed by a horizontal well hole that flows to the gas layer of the earth. The well is divided into smaller sections and these sections are fractured in sections. Fracking fluid (7 million litres of water is used, several thousand tonnes of sand and 200,000 tonnes of chemicals (de Rijke, 2013)) is then pumped into the ground at high velocity. Cracks are produced in the rocks, the sand in the mixture prevents cracks from closing again. The water is then pumped out and natural gas is now easily obtained. (BBC News, 2016). The first well was constructed in 1949 and as a result of a technology
While it is true “fracking”, a procedure to obtain natural gas removal from shale formations, it is also true there have been infrastructure security issues associated with this practice. Furthermore, there have been ecological considerations from fracking brought to the forefront by countless environmentalists. Indeed, hydraulic fracturing, as it is referred to, is a process by which shale gas and oil is uprooted from a depth far below the earth’s exterior. The process of extracting shale gas and oil is employed aggressively while water is forced deep beneath the earth surface through a geological arrangement. From this arrangement, oil and gas is exerted back to the earth’s surface. Moreover, once the hydraulic fracturing process is
