Oil well fracking s widely used in oilfield.

Oil well fracking of new wells in the reservoir is low porosity, fluid flow out; or old older oil wells are blocked, the oil flow resistance is large, with high pressure and a certain liquid pressure to open the bottom of proppant into the fracture It is supported, thereby enhancing the formation conductivity, to achieve an end yield very effective technological measures. It is a production efficiency, enhanced oil recovery process for a very important and is widely used in oilfield.
