Fracking in the United States - Ballotpedia

Hydraulic ,fracturing,, also known as fracking, is a ,method, of oil and natural gas extraction.The process involves injecting ,fluid, into subterranean rock formations at high pressure. The high-pressure ,fluid, produces a fracture network that allows crude oil and natural gas inside dense rocks to flow into a wellbore and be extracted at the surface. The ,fluid, (known as frac ,fluid,) contains between ...
