To accomplish this, the polysaccharide is extensively degraded through the use of a variety of chemical additives that were included in the ,fracturing fluid, formulation. The resulting ,flowback fluid, is not useful, and generally requires disposal. A new hydraulic ,fracturing fluid,, whose rheology is reversible and is controlled by pH, eliminates the need for polymer degradation. Because of this uniform viscosity reversal, the recovered frac ,fluid, volume after well ,flowback, …
