Petropedia - What is Flowback? - Definition from Petropedia

Flowback is, a water-based solution that flows back to the earth's surface after completing the hydraulic fracturing of a shale gas reserve., This water-based solution consists of chemical additives, mud, clay, dissolved metal ions and TDS (total dissolved solids). The water becomes murky because of the abundance of suspended particles.
