Optimizing Fracturing Fluid Viscosity for Efficient Proppant Transport

Fracturing fluids experience exceedingly high shear rates when passing through tubing, casing, or small-diameter perforations. However, as the fluid enters the formation after traversing the perforations, the shear rate decreases substantially. Importantly, the viscosity of the fracturing fluid can be quickly restored. The fracturing fluid is anticipated to achieve optimal recovery within a brief duration to facilitate the efficient transportation of proppants into the fracture without any interruptions.
