Fracking in the United States
History Non-hydraulic fracturing. Fracturing as a method to stimulate shallow, hard rock oil wells dates back to the 1860s. Oil producers in Pennsylvania, New York, Kentucky, and West ia used nitroglycerin (liquid at first, and later solid) to break up the oil-bearing formation. The method was later applied to water and natural gas wells. The idea of using acid as a nonexplosive fluid ...

Fracking
Fracking (also known as hydraulic fracturing, hydrofracturing, or hydrofracking) is a well stimulation technique involving the fracturing of bedrock formations 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 …
