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).
