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 ...
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 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.

Hydraulic fracturing, or fracking, has been around for a long time. However, it wasn't until the last couple of years that it became truly revolutionary in terms of oil and natural gas production.
Fracking, shorthand for hydraulic fracturing, is set to become a cornerstone of President-elect Donald Trump's energy agenda. While it is worth noting that the U.S. is producing more oil and gas ...
Hydraulic fracturing involves injecting a high-pressure mixture of water, sand and chemicals underground to fracture subterranean layers of rock and release oil and gas. The practice is more ...
Germany also had the largest hydraulic fracturing jobs in Europe, using up to 650 tonnes of proppant per well. Most German fracs used water- or oil-based gels. [34] The most popular target formation for hydraulic fracturing was the Rotliegend Sandstone. Hydraulically fractured wells are today the source of most of German natural gas production.
Hydraulic fracking without the water? Photo credit: Flickr/Snap Opponents of hydraulic fracturing have many criticisms of the process. From the chemicals injected into the ground to the heavy ...
