Fracking

AAA

DEFINITION of 'Fracking'

A slang term for hydraulic fracturing. Fracking refers to the procedure of creating fractures in rocks and rock formations by injecting fluid into cracks to force them further open. The larger fissures allow more oil and gas to flow out of the formation and into the wellbore, from where it can be extracted.

Fracking has resulted in many oil and gas wells attaining a state of economic viability, due to the level of extraction that can be reached.

INVESTOPEDIA EXPLAINS 'Fracking'

Petroleum engineers have used fracking as a means of increasing well production since the late 1940s. Fractures can also exist naturally in formations, and both natural and man-made fractures can be widened by fracking. As a result, more oil and gas can be extracted from a given area of land.
