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 ...
Maryland introduced a temporary fracking ban in 2015, [117] which was made permanent in 2017. [118] [119] Washington joined these states by banning hydraulic fracturing in May 2019. [120] A type of fracking technique called slickwater fracking was used in Texas in 1998 to complete natural gas wells in the Barnett Shale. [121]
The boom in U.S. oil and gas production is unprecedented in modern America. As recently as October 2005, we were importing 4.56 million barrels of petroleum-based products per day , while ...
Crude oil production Natural oil seeps such as this in the McKittrick area of California were used by the Native Americans and later mined by settlers.. The history of the petroleum industry in the United States goes back to the early 19th century, although the indigenous peoples, like many ancient societies, have used petroleum seeps since prehistoric times; where found, these seeps signaled ...
US shale gas basins, 2011. Shale gas in the United States is an available source of unconventional natural gas.Led by new applications of hydraulic fracturing technology and horizontal drilling, development of new sources of shale gas has offset declines in production from conventional gas reservoirs, and has led to major increases in reserves of U.S. natural gas.
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.

Fracking in Canada was first used in Alberta in 1953 to extract hydrocarbons from the giant Pembina oil field, the biggest conventional oil field in Alberta, which would have produced very little oil without fracturing. Since then, over 170,000 oil and gas wells have been fractured in Western Canada.
