The water is mixed with sand and chemicals to pump at high pressure into the shale rock. According to U.S Geological Survey (USGS) “This process is intended to create new fractures in the rock as well as increase the size, extend, and connectivity of existing permeability rocks like tight sandstone, shale, and some coal beds to increase oil and/or gas flow to a well from petroleum bearing rock formations”. The shale rocks contain the oil and gas. The shale rock will fracture from the fracturing fluid, which will hold the crack open and allow the natural gas to flow from the rock formation to the …show more content…
During the process of hydraulic fracturing, the equipment used for drilling releases methane emissions. The EPA and other federal agencies are finding new technologies to reduce methane emissions. However, during the process of hydraulic fracturing the equipment used for drilling releases methane emissions. Methane is the most toxic greenhouse gas. According to Finkel and Hay, Volatile organic compounds and diesel particulate matter, for example, result in elevated air pollution concentrations that exceed US Environmental Protection Agency (EPA) guidelines for both carcinogenic and non-carcinogenic health risks” (p.
