Hydraulic fracturing - Ditudo

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 ...

Wastewater is produced in shale gas operations mainly during the ,flowback, phase, when a portion of the ,fracturing fluid, returns to the surface after hydraulic ,fracturing,. Additional to proppant and chemicals initially present in the ,fracturing fluid,, the returned water will have picked up a variety of elements from contact with the shale rocks, including NORM.
