Hydraulic fracturing is a well completion technique used to break up the rocks around a well to increase the flow of oil and natural gas. It involves pumping fluid into a wellbore to create enough pressure to fracture the hydrocarbon-bearing rock layer. The fracturing takes place at …

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 ...

5/6/2015, · Two commonly used terms, flowback water and produced water, have been used when addressing hydraulic fracturing samples. The flowback water is the immediate return of injected fracking fluids, and the produced water is the term used to describe the water that is mixed with formation water (native to the well) and returns at a later time, during the production of oil and gas recovery.

Once the fractures have been created, injection ceases and the fracturing fluids begin to flow back to the surface. Materials called proppants (e.g., usually sand or ceramic beads), which were injected as part of the frac fluid mixture, remain in the target formation to hold open the fractures.

Polymers in the flowback fluid can be in different states of solution and have significantly different molecular weights from the polymers that were pumped downhole. In many cases, a breaking agent is used to reduce polymer viscosity, which promotes HF fluid flow from the fracture and helps the proppant stay in place during flowback.

The ,purpose, of frac ,fluid flowback, is to outflow the ,fracturing fluid, and prevent the proppant backflow, which determines the effect ,of fracturing fluid flowback,. The ,fracturing, treatment in field lacks relevant theoretical models for prediction. Therefore, this work focuses on establishing the ,flowback, model of hydraulic ,fracturing, for multilayer fractured wells.
