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 ...
Hydraulic fracturing is commonly used in some coalbed methane areas, such as the Black Warrior Basin and the Raton Basin, but not in others, such as the Powder River Basin, depending on the local geology. Injected volumes tend to be much smaller than those of either tight gas wells or shale gas wells; a 2004 EPA study found a median injected ...
Hydraulic fracturing of horizontal wells in unconventional shale, silt and tight sand reservoirs unlocks gas, oil and liquids production that until recently was not considered possible." [ 7 ] Conventional oil production in Canada was on a decrease since about 2004 but this changed with the increased production from these formations using ...
Drilling and hydraulic fracturing have made the United States a major crude oil exporter as of 2019, [11] but leakage of methane, a potent greenhouse gas, has dramatically increased. [ 12 ] [ 13 ] Increased oil and gas production from the decade-long fracking boom has led to lower prices for consumers, with near-record lows of the share of ...
Ukraine has a long history of hydraulic fracturing, since it has been used there since the 1950s. [88] There has also been a strong recent interest of the hydraulic fracturing industry in Ukraine. [89] According to the U.S. Energy Information Administration, Ukraine has third-largest shale gas reserves in Europe at 128 trillion cubic feet. [90]
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.

In the 1980s and 1990s, the company experimented with application of different techniques of hydraulic fracturing of the Barnett Shale of Texas, eventually finding the right technique to economically extract the natural gas in the formation. The approach was widely adopted by the gas industry and spawned a new gas boom in North America.
