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 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.

The regulation and implementation process of hydraulic fracturing is a complex process involving many groups, stakeholders, and impacts. The EPA has the power to issue permits for drilling and underground injection, and to set regulations for the treatment of waste at the federal level.
Diagram of Hydraulic Fracking Machinery and Process Increases in seismic activity following hydraulic fracturing along dormant or previously unknown faults are sometimes caused by the deep-injection disposal of hydraulic fracturing flowback (a byproduct of hydraulically fractured wells), [31] and produced formation brine (a byproduct of both ...
The process of hydraulic fracturing. Hydraulic fracturing, also known as fracking, is a process used to extract oil and natural gas. The process to extract oil and natural gas begins with thousands of gallons of water, mixed with a slurry of chemicals, some of which are undisclosed.
In 2011, Wright founded Liberty Energy, the Denver-based oil and gas company that has worked primarily in hydraulic fracturing, the drilling technique known as fracking that blasts bedrock with ...
In the US, about 750 compounds have been listed as additives for hydraulic fracturing, also known as ingredients of pressurized fracking fluid, [9] in an industry report to the US Congress in 2011 [10] [11] The following is a partial list of the chemical constituents in additives that are used or may have been used in fracturing operations. [12]
Americans casually familiar with hydraulic fracturing, the new drilling technology that led to a surge in U.S. oil and gas production starting around 2010, may think ample energy sources now mean ...
