Hydraulic fracturing - Wikipedia
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 ...

19/11/2014, · As mentioned above, the clear fracturing flowback fluid is mainly composed of VES which is usually cationic ammonium surfactant and AOS is anionic. When cationic and anionic surfactants are used together, the strong electrostatic attraction leads to the adsorption of more surfactant molecules on the oil/water interface [36] , which results in the appearance of lowest IFT in mixed catanionic systems.

Fracking has been in common use by the petroleum industry in Canada since at least the mid-1960s. Massive hydraulic ,fracturing, has been widely used in Alberta since the late 1970s to recover gas from low-permeability sandstones of the Spirit River Formation. The method is currently used in development of the Cardium, Duvernay, Montney and Viking in Alberta, Bakken in Saskatchewan, Montney and ...

Abstract: Hydraulic ,fracturing, is considered as an effective approach for the development of tight oil reservoirs. Unlike conventional reservoirs, after a large volume injection of the ,fracturing fluid,, the ,flowback, rate in tight oil reservoirs is considerably lower whereas the underlying mechanism explaining water retention remains unclear.
