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 ...
Fracking involves injecting a high-pressure mixture of water, sand and chemicals into underground rock formations to release oil and natural gas. This technique has revolutionized energy ...
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 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.
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, short for hydraulic fracturing, is an oil and gas extraction technique that involves injecting rocks with a mix of water, sand and chemicals. But why is it a big deal? Here are five ...
Modern day fracking equipment is capable of pumping anywhere from 800 to 4200 gallons of water per minute, at pressures ranging from 500 to 20,000+ psi. [172] Once the injection process is complete and gas has entered the well, anywhere between 10 and 30 percent of the fluid injected will flow back into the well as wastewater for disposal.
Nearly three years after Gov. Gavin Newsom directed it, California’s oil and gas industry regulator kickstarted a process to outright ban hydraulic fracturing, the fossil fuel extraction method ...
