Impact Of Stimulation At The Marcellus On The Environment

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

An individual’s environment plays a pivotal role in their overall health. The environment can affect a range of physical and mental processes, and is considered a defining factor of well-being. As a result, specific geographic areas are instrumental in shaping an individual’s health profile. This is clearly seen in the disparity between those living in areas exposed to toxic substances, versus individuals living in clean environments. Individuals in unpolluted environments experience the advantage of a body system free from the barrage of chemical assault. Unfortunately, people who live near toxic wastes or byproducts of industry, have a body that is in constant defense of attack. This natural defense mechanism can prove

“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

Natural gas is a fossil fuel that plays a critical role in the demand and supply of energy in the United States. It is considered to be a clean burning transition fuel. Compared to coal and oil, natural gas combustion does not generate as much pollution and is therefore considered an ideal partner for renewable energy resources. Natural gas is extracted from shale formations underground that require horizontal drilling and hydraulic fracturing – “hydrofracking” or “fracking”. This drilling and extraction method is currently considered a global widespread issue due to the rapid increase in the amount of new gas wells that threatens the quality of water around the source (Entriken, Evans-White, Johnson & Hagenbuch, 2011).

The Marcellus Shale rock formation harbors the largest natural gas reserve that runs from New York to Tennessee. (Federman 2010 p.35) The only way to extract the natural gas is to use the process of hydrofracking. The process of hydrofracking uses a mixture of water, sand and chemicals to drill and fracture the Marcellus Shale to extract the natural gas. Clean water is used from local aquifers to produce the water mixture called “slurry” which is made up of 99% clean water (Rush 2010 p.28). The slurry additives are described in the journal article “In the Wake of the Shale Revolution: A Primer on Hydraulic Fracturing Fluid Chemical Disclosure” as, 3

The water mixture used to break the shale rock contains sand as well as over 600 different chemicals. The amount of water needed just for one gas well to take place is over eight million gallons. Not only do these natural gas wells use up so much water, the methane gas and chemicals in the water contaminate nearby groundwater, causing the people who drink it to become very ill and suffer serious mental and physical injuries. Most of these companies who are in the business of drilling gas wells do not show what really goes on behind the scenes. The leftover fracturing fluid, which are retrieved after the fracking, is only half of what first went down the well. Not only is this a problem because the chemicals that are left sink further down into the ground but they are also not biodegradable, which could go on to contaminate more

Hydraulic fracturing in combination with advancement in directional drilling has made it possible to economically extract oil and gas from unconventional resources. The growth in U.S. oil and gas exploration and production made possible by the increase in use of hydraulic fracturing, has raised concerns about its potential to impact human health and the environment. Concerns have been raised by the public about the effects of hydraulic fracturing on quality and quantity of drinking water resources. The hydraulic fracturing water cycle includes five main activities: the withdrawal of ground or surface water needed for hydraulic fracturing fluids; the mixing of water, chemicals, and proppant on the well pad to create the hydraulic fracturing fluid; the injection of hydraulic fracturing fluids into the well to fracture the formation, the return of injected fluid and water produced from the formation to the surface; and the reuse, treatment and disposal of wastewater generated at the well pad, including produced water (U.S. EPA, 2015). With the water cycle being so massive and prolonged, the presence of potential negative impacts is greatly increased.

The single most pronounced criticism of hydraulic fracturing is the claim that it pollutes groundwater, yet there is little or no evidence to prove such a claim. A landmark

The process of hydraulic fracturing – shooting water, sand, and chemicals at high pressure into underground wells to release natural gas – is a divisive issue: Some say it dumps chemicals into ground water supplies, others argue it causes earthquakes, and still others think it can revolutionize America’s energy industry.

There is a lot of controversy over the new practice of getting to fresh natural gas stored in the shale under our feet. The process has been named hydraulic fracturing, and as you can imagine, it involves water (hydro) and breaking stuff (fracking). The results that many people have been experiencing close to where this technique is used seem to be having

In 2000, shale beds where the number one source of America’s constant need for gas. Most of that production increase has come about to the growing need of hydraulic fracturing, also known as “fracking”, which is a process used to release oil or gas from underground formations that are otherwise too hard to mine with other tools. Over the past few years, advances in fracking technology have made huge reserves of natural gas in America economically recoverable. According to the Energy Information Administration, shale gas plays, or fields, in the United States, most notably the Marcellus, in Pennsylvania, West Virginia, and New York, and the Barnett, in Texas, are said to contain enough natural gas to give power to the country for a hundred and ten years. With the everlasting specter of energy independence, some have argued that such efforts to recover natural gas need to be expanded. Activists concerned with fracking’s potential environmental hazards view the new process as a serious threat to our environment. There are many different opinions on wether or not fracking is a safe way to gain our gasoline, and to meet the growing demands of gasoline around the world. The process of fracking creates cracks that come from wells into oil and gas formations by pumping highly pressurized fluids, ceramic beads, sand, and a mixture of chemicals, into the gas formation. As this fluid holds the underground fissures open, oil and gas fly up the well to the surface where they are

In the process of fracking, problems can occur and there can be a possibility of water contamination. During fracking underground water supplies can be exposed to shale gas and contaminate the water or there could be a cement failures and infiltration from soil or even water transportation incidents (Beaver 127; Penning et al. 1156). This can happen very easily and can cause the water to get contaminated. In one case, “EPA found evidence of groundwater contamination with benzene, xylenes, gasoline range organics, diesel range organics, and total volatile hydrocarbons in shallow wells that lie above 169 gas-producing wells that were hydro fractured.”(Penning et al. 1156). Most of these chemicals found in the water are harmful to the body, can

Another problem that we know exists with hydraulic fracturing is the contamination of the water, the ground, and the air around the sites (Goldman pg. 2). It has been shown that “…residents living near the hydraulic fracturing sites are increasingly worried that the drilling process might be contaminating their well water, polluting streams, and releasing toxic gases into the air (Hobson).” Water sources, as well as the soil, are often polluted from flowback fluid and from production brine (Hydro-Fracking pg.4). Flowback fluid is “the contaminated fluid that returns to the surface during the drilling process, and is estimated to be between 9% - 35% of the fluids injected during
