Essay On Hydraulic Fracturing

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 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,

Hydraulic fracturing, or fracking, is the process used to excavate oil and gas trapped in shale rock.

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

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).

‘Hydraulic fracturing/fracking is the process of injecting liquid at high pressure into subterranean rocks, boreholes, etc. to force open existing fissures and extract oil or gas’ (Oxford dictionaries, 2015).

Hydraulic fracturing is an increasingly common practice used to access otherwise unobtainable oil or natural gas reserves. While it shows promise as both a valuable economic resource as well as a source of energy independence, many oppose the practice due to alleged environmental dangers. In order to foster a greater understanding of the issues at hand, the following topics are discussed: what hydraulic fracturing is, how it is performed, and where it is located in the United States and abroad; how it has benefited the United States’ economy and how it can support the United States’ energy needs; legal and environmental issues; domestic and overseas regulations; and last but not least, what President Obama had to say about the practice in his 2012 Executive Order. The paper concludes with the author’s personal opinion regarding regulation of the practice here in the United States.

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 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.

In today’s society the issues of producing energy is becoming more and more scare which, constantly posses the question, “How will energy be obtained in order to sustain future generations?” Hydraulic fracturing, informally known as fracking is believed to be an effective alternative to provide us with the energy we need to fuel tomorrow. Hydraulic fracking was first used at Texas Stanolind Oil and Gas Cooperations in 1947. However, it was not until 1949 that The Halliburton Oil Well Cementing Cooperation was given a licensee to use hydraulic fracturing. Since then a combination of two advanced methods have been introduced and incorporated (4). These methods are slick-water hydraulic fracturing and precision drilling of wells. Nevertheless,

Hydraulic fracturing, or fracking, is a method in which a high pressured water, sand, and chemical mix is injected into a well in order to fracture rock leading to the releases of gas or oil to the surface, see Figure 1 for illustration. Fracking was invented in the 1940s but has only become economical in the past few decades due to advancements in technology. The top fracking regions in the

While vertical wells do yield gas, they are mainly used as a base to connect several horizontal wells, which is where the money lies in the industry. After drilling, about “2 million to 10 million gallons of water [is used] to extract the gas” (Marsa 3-4). However, high pressured water alone will not break away the shale rock, therefore sand is added to enable further fracturing. The controversial issue fueling the debate is the third substances added to the water which allow the natural gas to escape for collection. “A cocktail of friction-reducing lubricants [are used] to make the water slick enough to slide through the pipes swiftly” (Marsa 4). A geochemist by the name of Tracy Bank conducted a study at SUNY Buffalo which concluded that the lubricant contained an abundance of toxic metals, “including uranium, barium, chromium, zinc and arsenic” (Marsa 2). This is just a short list of the negative compounds used in fracking. It is likely that the public will never get the full story as to the composition of the lubricants, as major fracking companies refuse to release that information, “claiming that doing so would reveal trade secrets” (Rahman 1). So where do these contaminants end up? After reaching the surface, the waste is emptied into tanks for storage. However, sometimes ponds are also used to hold the pollutants, therefore releasing the harmful toxins into runoffs. Once the gas has

Around the world, countries are dependent on oil and more often than not, foreign oil. The U.S. is at a time where they believe buying foreign oil supports terrorism and hurts our economy. Shale formations deep underground that spread all over the U.S. have been found to contain natural gas. This includes the Marcellus Shale formation and the Utica Shale formation, which can be found all throughout New York State and down the East Coast (Hydro-Fracking pg.1). To get at this abundance of gas underground, hydraulic fracturing was invented, but this new method of gas extraction safe for the environment and for the people around it?

Passey et al. (2010) claimed that there is a large variability in lithology between shale plays and even within a single shale formation (Passey et al. 2010). Britt and Smith (2009) emphasized the importance of geomechanics and the state of stress of a shale play for a successful hydraulic fracturing stimulation (Britt and Smith 2009). In addition, Rickman et al. (2008) stressed that the mechanical rock properties, such as brittleness and mineralogy, are fundamental in completion designs. While ductile shale tend to restore any fracture formed, brittle shale often have natural fractures which react to hydraulic fracturing (Rickman et al. 2008). In general, the Young’s Modulus of the shale measured parallel to the bedding plane is greater than that measured perpendicular to the bedding plane. Sone and Zoback (2013) explained the role of anisotropy on the
