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.
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 ...

Later the methane was linked to nearby fracking operations. [174] [175] January 1, 2015 – Irving, earthquake [176] May 7, 2015 - An oil tank battery caught fire, north of Whitesboro. [177] May 19, 2015 – Fracking well blew out in Karnes County, Texas, spraying a toxic mix of chemicals, and forcing the evacuation of 20 families. [178] [179]
In the United Kingdom, the first hydraulic fracturing of an oil well was carried out shortly after discovery of the West Sole field in the North Sea in 1965. After the industry started to use intermediate and high-strength proppants in the late 1970s, hydraulic fracturing became a common technique in the North Sea oil and gas wells.
Hydraulic fracturing is the propagation of fractures in a rock layer by pressurized fluid. Induced hydraulic fracturing or hydrofracking, commonly known as fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas and coal seam gas), or other substances for extraction, particularly from unconventional reservoirs. [1]
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.
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.
