pressurized ,fracturing fluid, is injected to create and propagate the fracture, with the drawback that ,fracturing fluid, recovery can be very low, even less than 10%. Moreover, this ,fracturing fluid, can enter the formation and block the rock pores, thus reducing the effective permeability to gas and causing gas ,production, impairment.

This ,test, was performed to compare the ability of various ,flowback, aids to not form stable emulsions when contacted with residual oil. Various ,flowback, aids were mixed at a dosage of one gallon per 1000 gallons of injection brine. 50 ml of brine containing the ,flowback, aid was mixed with 50 ml of oil and blended at high speed in a Waring Blender to emulsify the two liquids.

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 ...

Once ,fracturing, is completed, a portion of the injected ,fluid,, called ,flowback,, is recovered and stored in open pits or tanks. Because ,flowback, often has high chloride concentrations, it is important that ,flowback, chemistry is properly characterized so that disposal can be carried out safely.
