Fracking Water: It's Just So Hard to Clean | HuffPost

Flowback, water (which literally “flows back” during the fracking process) is a mixture of fracking ,fluid, and formation water (i.e., water rich in brine from the targeted shale gas-rich rock). Once the chemistry of the water coming out of the well resembles the rock formation rather than the fracking ,fluid,, it is known as produced water and can continue to flow as long as a well is in ...

Flowback Fluid. The target reservoir locates in the piedmont region of Tarim Basin, which is characteristic of desert environment, great reservoir depth (over 3000 m), and high reservoir temperature (approximately 140°C) [ 38 – 40 ]. To hydraulically fracture this reservoir,, cross-linked guar, was used as the fracturing fluid.

1/11/2018, · After years of experiments in the United States, reuse of FW for preparing fracturing fluids after appropriate treatment has been a widely applied treatment (U.S.EPA., 2016). A temporal storage of FW in surface impoundments or tanks, and a subsequent treatment such like filtration and/or precipitation for metal removal are needed to enable the reuse ( Barbot et al., 2013 ).
