Quizplus · Accepted Answer

Hydraulic fracturing or fracking is the process used to access oil and gas reserves that are trapped in rocks deep underground. In fracking, a high-pressure mixture of water, sand, and chemicals is injected into the rock to create small fractures, which allow the oil and gas to flow more easily to the surface. This technique has been widely used in the oil and gas industry in North Dakota and other areas of the United States. Explosive mining, compressive extraction, and chemical immersion are not commonly used methods for accessing oil reserves.
