Hydraulic fracturing [a] is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep rock formations through which natural gas, petroleum ...
A study of rural communities around fracking sites in Pennsylvania found that while there was some local support of fracking as a source of jobs and a boost to small businesses, there was more skepticism of if these jobs would stay within the community at all, and if there would be a significant 'bust' to the economy after the natural gas dried up.
Environmental Protection Agency illustration of the water cycle of hydraulic fracturing. Fracking in the United States began in 1949. [1] According to the Department of Energy (DOE), by 2013 at least two million oil and gas wells in the US had been hydraulically fractured, and that of new wells being drilled, up to 95% are hydraulically fractured.
According to the Department of Energy, fracking now accounts for 95% of new wells in the U.S., generating two-thirds of the total gas market and nearly half of the nation’s crude oil production.
Gasland is a 2010 American documentary film written and directed by Josh Fox.It focuses on communities in the United States where natural gas drilling activity was a concern and, specifically, on hydraulic fracturing ("fracking"), a method of stimulating production in otherwise impermeable rock.
Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, [1] air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.
Wright, the chief executive of oilfield services group Liberty Energy, helped launch the American Shale Revolution of the mid-2000s that significantly increased US production of oil and natural gas.
Fracking According to available studies on its environmental relevance, the fracking technology in unconventional natural gas production – particularly in shale gas production – is a technology with enormous potential risks. The effects on humans, nature and the environment are scientifically not yet sufficiently clarified.
