16/4/2020, · The ,fluid, density affects the surface injection pressure and the ability of the ,fluid, to ,flow back, after the treatment. Water-based fluids generally have densities near 8.4 ppg. ,Oil,-base ,fluid, densities will be 70 to 80% of the densities of water-based fluids. Foam-,fluid, densities can be substantially less than those of water-based fluids.

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.
