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 has changed the energy scene as a result of many technological advances. Fracking uses both historically-known vertical and horizontal drilling techniques which are used in tandem to extract oil and gas. This process can occur at depths over 10,000 feet deep. The primary product of hydraulic fracturing is natural gas which ...
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.
Here are 15 charts that tell the story of the U.S. natural gas market. Rise of horizontal drilling and hydraulic fracturingIn the past few years, new. The story of U.S. natural gas gets referenced ...
A natural-gas processing plant in Aderklaa, Austria. Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing contaminants such as solids, water, carbon dioxide (CO 2), hydrogen sulfide (H 2 S), mercury and higher molecular mass hydrocarbons to produce pipeline quality dry natural gas [1] for pipeline distribution and final use.

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.
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, and brine will flow more freely.
The fractionation process yields ethane, propane, butane, isobutane, and natural gasoline. Transportation: Oil and gas are transported to processing facilities, and from there to end users, by pipeline , tanker/barge , truck , and rail .
