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.
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.
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 paved the way for the U.S. to become a leading oil and gas producer Prior to the advent of fracking, U.S. oil production was on the decline, but the new technology turned that around.
Hydraulically fractured wells are today the source of most of German natural gas production. [ 35 ] In February 2013, the government of Chancellor Angela Merkel announced draft regulations that would allow for the exploitation of shale gas deposits using the same fracking techniques common in the U.S., with the exception only of wetland areas ...
Some Oklahoma energy companies are once again focusing on investor payouts as the number of active drilling rigs fell over the past year.. According to Baker Hughes' North America Rig Count, there ...
Drilling an oil and gas well at a location or well pad site at which drilling has occurred previously within five (5) years prior to the date of spudding the well. 3. Drilling an oil or gas well within a developed field for which an approved land use plan or any environmental document prepared pursuant to NEPA analyzed such drilling as a ...
