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 ...

The formation of scale deposits upon tubing, casing, perforations, and even on the formation face itself, can severely constrict ,fluid, flow and reduce the production ,rate, of oil and gas wells. In addition to lost production, a considerable portion of the workover budget is expended in efforts to remove these deposits and prevent their recurrence.

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.
