Can Produced Or Flowback Water Be Reused As Fracturing Fluid?
Can Produced Or Flowback Water Be Reused As Fracturing Fluid?

These processes are repeated for every well, which begs the question—is there a way of reusing the, water flowed back, or produced from each well for, fracturing, the next one? With the drilling of several wells from a single pad, this would mean that the same, water, could be used for each well on the pad with major reductions in freshwater usage, overall cost and environmental damage.

1/4/2018, · An investigation was conducted to study the reutilization of clear ,fracturing flowback, fluids composed of viscoelastic surfactants (VES) with additives in surfactant flooding, making the process more efficient and cost-effective. The clear ,fracturing flowback, fluids were used as surfactant olefin sulfonate (AOS) for enhanced oil recovery (EOR).

Some CBM reservoirs have extremely low porosity and permeability, which need hydraulic ,fracturing, to achieve greater yields. Furthermore, the reservoir ,fluid, flow gradually changes from single-phase water flow to gas-water two-phase flow during the production process, which can increase seepage resistance and change the form of pressure propagation.
