Pros And Cons Of Hydraulic Fracturing

Better Essays

Imagine a world less dependent on oil; a world that wars are not started over oil. This is the future the people that support hydraulic fracturing envision. The rapid development of unconventional sources of oil and natural gas using hydraulic fracturing has generated a great deal of controversy. As coal and oil struggle to remain the popular source of fossil fuel, fracking has gained a new spotlight in the war on energy. Hydraulic fracturing, also known as hydrofracking, hydrofracturing or simply, fracking, is the process of extracting natural gas from gas shales. The term gas shales refers to natural gas that is extracted from porous rocks that hold gas. A vertical well is drilled hundreds of feet into the ground, through this well, hydraulically …show more content…

But the demand for water used in fracking appears to be manageable in areas like Pennsylvania and Ohio where surface water, which is renewable, is used. In areas like West Texas where groundwater must be tapped, existing permitting schemes can be used to allocate scarce local water supplies. Ideally, increased recycling of fracking fluid will reduce the demand on water supplies nearly everywhere. In some regions of the country where fracking operations are taking place, there are concern that excessive extraction of surface water and groundwater will result in periods of water shortages that impact agricultural irrigation, drinking water wells, or surface water levels. Of perhaps equal concern are increasing groundwater withdrawals by agriculture resulting in the depletion of aquifer reservoirs. Fracking operations require 2-10 million gallons of water per well, per fracture (Boudet, 2014). This puts the local reservoirs in the danger zone and the people that rely on these groundwater resources in …show more content…

Fracking is an industrial activity that requires the establishment of a work site, called a "well pad," from which multiple horizontal wells can be drilled. A well pad and associated infrastructure (roads, impoundments, pipelines, etc.) covers an average of 8.8 acre There are a number of stressors from hydraulic fracturing operations that may affect wildlife health. A study done by a USA Government Accountability Office showed that “of the 575 National Wildlife Refuges in the United States, 105 contain a total of 4406 oil and gas wells” (Burton, 2014). The construction and transportation of fracking operations lead to a number of earth-disturbing activities, such as clearing, grading, and excavating land to create a pad to support the drilling equipment or other necessary industrial process materials. In general, well pads increase the potential for sediment erosion on and off location because of the destruction of vegetation. These newly constructed well pads also often require construction of access roads to transport equipment and other materials to the site. If sufficient erosion controls to contain or divert sediment away from surface water are not established, then surfaces exposed to precipitation and runoff could carry sediment and other harmful pollutants into nearby rivers, lakes, and streams. The construction of
