Fracking - Wikipedia
WebFracking (also known as hydraulic fracturing, fracing, hydrofracturing, or hydrofracking) is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid.
Fracking | Definition, Environmental Concerns, & Facts
WebMar 31, 2024 · Fracking, in natural gas and petroleum production, injection of a fluid at high pressure into an underground rock formation in order to open fissures and allow trapped gas or crude oil to flow through a pipe to a wellhead at the surface. Fracking has raised concerns over its economic and environmental consequences.

WebJan 14, 2015 · Fracking is a technique used to extract oil or gas from underground shale formations. A mixture of water, sand and chemicals is injected at high pressure into the rock, causing it to fracture (crack). This allows oil and gas contained in the rock to be recovered, often from sources that were previously inaccessible or uneconomical to explore.
