Hydraulic Fracturing

Hydraulic fracturing (Fracking, Fracing or hydrofracking), is the sophisticated process of creating a fracture in a rock layer through the use of pressurized fluids in order to release petroleum or natural gas for collection.

The actual act of fracturing, known as the frack job (or frac job), is done from a wellbore drilled into reservoir rock formations. The energy from the injection of a highly pressurized fluid, such as water, creates new channels in the rock which can increase the extraction rates and ultimate recovery of fossil fuels.

Hydraulic fractures may be natural or created by human activity, and are extended by internal fluid pressure which opens the fracture and causes it to extend through the rock. Natural hydraulic fractures include igneous dikes, sills and fracturing by ice as in frost weathering. Man-made fluid-driven fractures are formed at depth in a borehole and extend into targeted formations. 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.
