Hydraulic fracturing is the propagation of fractures in a rock layer caused by the presence of a pressurized hot milf fluid. Hydraulic fractures may form naturally, as in the case of veins or dikes, or may be man-made in order to release petroleum, natural gas, coal seam gas, or other substances for extraction, where the technique is often called fracking or hydrofracking. This type of fracturing, known colloquially as a frack job (or frac job) is done from a wellbore drilled into reservoir rock formations. The energy from the injection of a highly-pressurized fracking fluid creates new channels in the rock which can increase the extraction rates and ultimate recovery of fossil fuels. The fracture width is typically maintained after the injection by introducing a proppant into the injected fluid. Proppant is a material, such as grains of sand, ceramic, or other particulates, that prevent the fractures from closing when the injection is stopped.
The practice of hydraulic fracturing has come under scrutiny internationally due to concerns about the environmental impact, health and safety, and has been suspended or banned in some countries
