A concept of hydraulic fracturing flowback treatment using ...

The possibility of desalinated water production from hydraulic ,fracturing flowback, by electrodialysis reversal (EDR) was investigated. To simulate geochemical reactions of hydraulic ,fracturing fluid, with the formation rocks, ,fluid,-gas-rock reaction was performed in autoclave. Next, an EDR of hydraulic ,fracturing flowback, was simulated and the composition of diluate and concentrate was ...

Hydraulic ,fracturing, is a controlled, high-pressure injection of ,fluid, and proppant into a well to generate fractures in the rock formation containing the oil or gas. After the hydraulic fracture procedure is completed, the injected ,fluid, is allowed to ,flow back, into the well, leaving the proppant in the newly created fractures.

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 ...
