Flowback fluid is essentially fracturing fluid - which is a mixture of water, proppant and chemical additives -, that returns to Earth’s surface once the fracturing procedure has ceased and pressure is released,,, reversing the, direction of fluid flow. Flowback fluid wastewater will be directed through a separator at surface to capture wastewater and separate gas to flare.

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.

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.

Description. Large amounts of aqueous based ,fluid, are used in hydraulic ,fracturing, of tight formations to enhance gas ,production,. The pumped aqueous-based ,fluid, is not fully recovered during ,flowback, of well after the treatment resulting in increased water saturation, water blockage, clay swelling, reduced relative permeability, and long-lasting formation damage that impedes gas ,production,.
