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.

Hydraulic Fracturing | Alberta Energy Regulator

Because hydraulic fracturing operations do not use water after a well is fractured, opportunities to recycle fracturing fluid (flowback water) within the well are limited, so make-up water accounts for most of the water used. However, flowback water can be reused to fracture a different well, thereby contributing to the, make-up, water used in the hydraulic fracturing operation.
