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.

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).

Such a polymer slurry concentrate will readily disperse and hydrate when admixed with water at the proper pH, thus producing a high-viscosity aqueous ,fracturing fluid,. The ,fracturing fluid, slurry concentrate is useful in producing large volumes of high-viscosity treating fluids at the well site on a continuous basis.
