Discussion on the Ethical Implications of Hydraulic Fracturing by: Sebastian Potes 7/16/13 ! Abstract As concern grows over the environmental impact of hydraulic fracturing‚ implementing policy that protects people and their environment from these potential dangers becomes an essential piece of the renewable energy picture. Hydraulic fracturing‚ or fracking‚ is the technique of extracting oil and natural gas trapped under ground by injecting a mixture of water‚ sand‚ and chemicals into the

the pressure is the fracture gradient or the amount of pressure it takes to crack the rock. When the rock cracks‚ the fracturing fluid continues further into the rock pores‚ extending the cracks further. Then a material such as sand or other types of particulates are introduced to prevent the fractures from closing when the pressure of the fracturing fluid is removed. Fluids found within the rock formation include gas‚ oil‚ and salt water. Fracturing within the well (borehole) is controlled by methods

This form of fossil fuel extraction is gaining popularity in the United States. With the need to decrease our dependency on foreign energy supplies‚ hydraulic fracturing allows the US to extract a larger quantity of fossil fuels‚ making the drilling process more profitable

pressure changes that stimulated a distant fault causing it to slip. Further geomechanical analysis suggested that bedding planes in the Bowland Shale are so weak that it is inevitable that it will slip under stress and this provided a passage for fluid to flow out of the well and into the fault region (de Pater and Baisch‚ 2011). This occurrence was the first significant event that brought hydraulic fracturing under the spotlight in the UK. It was the beginning of a difficult course of action to

Fracking Before I began writing this paper I was neutral on the subject of natural gas fracking‚ I had never heard of it and had no idea how destructive this process of extraction was. The further I got on this report‚ the more furious I became that this was happening on US soil‚ and not only that but people in the highest levels of government were not only sanctioning it‚ but using their power in public office to advance the agenda of companies that they were either running before they cae into

Wells are drilled vertically hundreds to thousands of feet below the land surface. Fractures are created by pumping large quantities of fluids at high pressure down a wellbore and into the target rock formation. Hydraulic fracturing fluid commonly consists of water‚ proppant and chemical additives that open and enlarge fractures within the rock formation. These fractures can extend several hundred feet away from the wellbore. The proppants
