Hydraulic fracturing - Wikipedia

Hydraulic fracturing,, also called fracking, fracing, hydrofracking, fraccing, frac'ing, and hydrofracturing, is a well stimulation technique involving the ,fracturing, of bedrock formations by a pressurized liquid. The process involves the high-,pressure, injection of "fracking ,fluid," (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore ...

per well. Hydraulic ,fracturing, involves pumping large volumes of ,fluid, blended with proppant and chemicals at pressures necessary to fracture a hydrocarbon-containing formation. Once the fractures are created, proppants are placed within the fractures to hold them open and allow for the release and ,flowback, of fluids and hydrocarbons.

16/4/2020, · To create the fracture, a fluid is pumped into the wellbore at a high rate to increase the pressure in the wellbore at the perforations to a value greater than the, breakdown, pressure of the formation. The breakdown pressure is generally believed to be the sum of the in-situ stress and the tensile strength of the rock.
