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.

Economides and Martin (2008) and King (2010) reported that the main fluid additives are friction reducer, biocide, oxygen scavenger, scale inhibitor, wetting agent, breaking agent, and proppant. The fluids and their concentrations are selected on the basis of the petrophysics of the formation (Rickman et al. 2008).
