Hydraulic Fracturing, Fraccing

Hydraulic fracturing, or fraccing, is the fracturing of rock by a pressurized liquid. Induced hydraulic fracturing or hydro fracturing, commonly known as fracking, is a technique in which typically water is mixed with sand and chemicals, and the mixture is injected at high pressure into a wellbore to create small fractures (typically less than 1mm), along which fluids such as gas and oil may migrate to the well.
