16/4/2020, · The, viscosity, of the, fracturing fluid, is an important point of differentiation in both the execution and in the expected, fracture, geometry. Many current practices, generally referred to as "slickwater" treatments, use, low-viscosity fluids, pumped at high rates to generate narrow, complex, fractures, with low-concentrations of propping agent (0.2-5 lbm proppant added (PPA) per gallon).
