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 ...
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.
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.
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 United States Geological Survey notes that fracking involves injecting water into bedrock to loosen it and retrieving oil and gas deposits. What is fracking? How the process works.
Overall, permitted fracking operations accounted for just 2% of statewide oil production in 2021. CalGem estimated that the new ban, which it expects to be approved by the end of 2024, would have ...
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.
On the 40th anniversary of the Clean Water Act, environmental advocates aren't finished with their fight against fracking. A green coalition has banded together to halt hydraulic fracturing in ...
