UV and oxidation treatments are then used to effectively neutralize microbes and destroy residual polymers if any are left over from frac flowback. In addition to recycling produced water for use as frac water or reinjection for waterflood EOR, we can apply oilfield water treatment solutions to improve the quality of water destined for disposal.

Petropedia - What is Frac Flowback? - Definition from ...

Frac Flowback is a water-based solution which flows back into the earth's surface after the completion of hydraulic fracturing of shale gas reserves. This water-based solution consists of chemical additives, mud, clay, dissolved metal ions and total dissolved solids. The water is murky due to the high amount of suspended particles.

FLOWBACK AID FOR FRACTURING FLUIDS - Schlumberger ...

A flowback aid may be included in the fracturing fluid to reduce capillary pressure and water blocks, thereby improving the kinetics of the flowback and preventing or minimizing the leaving-behind of any substantial amount of the fracturing fluid. Flowback aids, such as surfactants, have also been shown to aid in the “clean-up” of the proppant pack, thereby accelerating the flow of hydrocarbons through the …
