Hydraulic fracturing

特許 係属中 Hydraulic fracturing is the fracturing of rock by a pressurized liquid. Some hydraulic fractures form naturally—certain veins or dikes are examples. Induced hydraulic fracturing (also hydrofracturing, fracking, and fraccing) is a well-stimulation technique in which a high-pressure fluid (usually water mixed with sand and chemicals) is injected into a wellbore in order to create small fractures (usually less than 1.0 mm wide) in the deep-rock formations in order to allow natural gas, petroleum, and brine to migrate to the well.
