The term “unconventional mining” refers to the removal of gas from unconventional deposits. This includes shale gas (shale rock), tight gas (certain sandstones mainly) and coal seam gas mining (from coal seams). (“Fracking in western Australia - the basics,” 2015) The extraction of Shale and tight gas in particular relies upon a controversial practice called hydraulic fracturing or “fracking”. This technique may also be used in coal seam gas extraction, although less frequently. Unconventional mining – mainly fracking - has become an increasingly politically sensitive issue in Australia and around the world, to the point where it may even help swing seats in regional areas. Conventional coal and gas mining does not involve extraction from unconventional reservoirs, and thus almost never involves fracking, although there are many other issues associated with it. (Hepburn & Cook, 2015) The fracking process itself involves drilling a deep well into an underground rock formation, which then has fluids pumped into it at extremely high pressures – pressures high enough to form small scale cracks in the extremely hard rock. The high pressure of the fluid causes the rock to shatter, after which the fluid is mostly withdrawn and gas is released. “Unconventional gas” is found in gas deposits trapped within deep geological formations, often within shale rock, coal deposits or tight sandstone. Most deposits exploited in Australia can be found close to east coast and also in the south of
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
In recent years there has been great concern over the growing demand for energy, and the lack of non-renewable energy resources to meet the demand in the future. In addition, the question of “sustainability”—the ability to balance social, economic, and environmental needs in energy production to meet both current and long-term requirements—has come to the fore. It is clear that America must expand energy production quickly, and that we must develop renewable, sustainable energy sources to meet long-term demand and protect our future. There are many proposed solutions, such as wind and solar power. But the technology for these resources is not yet fully developed, making them, at best, low-output alternatives. Because renewable sources are
“Fracking” isn’t a word that most people are familiar with unless they are well informed or active in local government or natural gas extraction. “Hydraulic fracturing, or fracking, involves extracting natural gas from shale formations underground” (Collier, Galatas, Harrelson-Stephens, 2008). During the process known as fracking, millions of gallons of water are shot underground into shale formations to help bring the natural gas trapped inside the formations to be released so that it can surface and become available for extraction. This is the technique that is used for traditional fracking methods. Although fracking increases the states natural gas production, it also carries some negative side effects that are affecting the state and its people.
“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
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).
Human health and environmental integrity are both at risk from fracking. However, it allows America to be self-sufficient in an energy driven world. In the end, the debate comes down to whether or not the risks outweigh the benefits. In his interview, Josh Fox brings up firsthand accounts of what fracking does to humans, animals, and the environment. Fox tells the story of Debbie May, a land owner who allowed oil companies to frack on her land. May owns serval cats and a horse, all of whom started losing hair and weight since the fracking started (Fox). This is on top of the fact that in several homeowners in various areas found that their water would light on fire after fracking started (Fox). Lastly, in Colorado, benzene is found in
Not only is breathing in the methane fumes a risk to health, but also methane is flammable. In Wyoming, a leaking methane gas well burst into flames, swaying the views of several individuals (Lavelle 109). Since this well not only leaked methane but also natural gas, this fire quickly expanded and burned a large flame. This fire lasted for months until the firefighters were finally able to put it out. Copious amounts of individuals became forced to evacuate and eventually, their homes would be engulfed in the flames. Another fire broke out, but this time it was located in a home. A family in Colorado, who lived near a fracking well were enjoying supper (Lavelle 109). Shortly after supper concluded the mother turned on the sink to wash
I became interested in hydraulic fracturing, commonly known as “fracking”, after watching the documentary Gasland II. It chronicled the experiences of those who inhabit areas in proximity to active fracking wells in Pennsylvania. Detailing how their lives had been affected by the drilling. Focusing primarily on water contamination and illnesses that potentially could be linked to the chemicals used in the drilling process. By the end, I had questions about the actual process and what chemicals were used. I was also left wondering about the existence of environment laws and monitoring, if any, which would have ensured the use of only substances safe for humans as well as the environment. Why would this process have been allowed if it
During the mid 2000s hydraulic fracking was starting to grow because ‘It was a good way to meet energy needs.”(source 5). Hydraulic fracking has been said to release chemicals and pollute drinking water.

Fracking is a technique designed to get gas and oil out of shale rock in the earth. Natural gas has been used for light and heat for more than 100 years, natural gas is considered one of the cleanest fossil fuel but since it is a fossil fuel it is also a finite resource. Natural gas industry developed a new drilling technique called hydraulic fracturing also known as fracking . fracking is a means of extracting natural gases from shale. Tons of chemicals some toxic are mixed with large amounts of water and sand and pumped up to 8,000 feet under ground. The pressure fractures the shale and allows the gas to freely move.
America has one of the highest energy consumption rates in the world. This demand has led to the popularization of the hydraulic fracturing industry. First introduced in the 1940s, hydraulic fracturing is method by which a well is drilled one to two miles below the Earth’s surface. The well then injects water and chemicals in the Earth that create fractures through which gas can flow through. Hydraulic fracturing, which is also known as fracking, became popular because of horizontal drilling in fracking is more efficient at extracting gas. As a result, a fracking boom ensued in which over a million wells were drilled in the United States in the past decade. However,
Texas the great lone star state, full of natural beauty that ranges from the majestic big bend national park in the Brewster County on the refreshing shores of the South Padre Island, Texas owns a plentiful quantity of natural resources, nevertheless the process of hydraulic fracturing commonly known as “fracking” taking place in Texas, will destroy our natural resources, turning our vast land of splendor into a methane ridden wasteland. However this is the time to unite against these companies that value money over sustainability. In the first place, fracking consist on drilling using a pressurized water, sand, plus a mix of chemicals to release gas from the rocks beneath the earth, this usually happens at 10,000 feet of depth, although this

Hydraulic fracturing is a process used in nine out of 10 natural gas wells in the United States, where millions of gallons of water, sand and chemicals are pumped underground to break apart the rock and release the gas. Scientists are worried that the chemicals used in fracturing may pose a threat either underground or when waste fluids are handled and sometimes spilled on the surface. The natural gas industry defends hydraulic fracturing, better known as fracking, as safe and efficient. Thomas J. Pyle, president of the Institute for Energy Research, a pro-industry non-profit organization, claims fracking has been “a widely deployed as safe extraction technique,” dating back to 1949. What he doesn’t say is that until recently energy
