Treatment of high viscosity fracturing flowback by ...
Treatment of high viscosity fracturing flowback by ...

In this paper, Fe/Ni catalyst was successfully applied in the treatment of the flowback fluid for the first time. The catalyst can improve the oxidation efficiency of electrolytic brine and reduce the viscosity of fracturing flowback during the treatment process. The effect of the Fe/Ni proportion on the catalytic performance was studied.

1/3/2021, · Holditch (1979) studied the effect of capillary force and relative permeability change on the, flowback, of, fracturing fluid, during hydraulic, fracturing, in tight gas reservoirs. The higher capillary pressure and the lower water phase relative permeability lead to water retention in the matrix near the, fracture, surface, which makes it difficult for the, fracturing fluid, to be returned to the surface.
