Increasing pressure during a fracture treatment has been attributed to the formation of a tip screenout, which occurs as a result of insufficient pad fluid volume or excessive leakoff. Results from a numerical simulator of fracture propagation that incorporates the effects of proppant concentration on fluid rheology, fracture transmissibility, and proppant transportability suggest that the observed pressure rise can result from the formation of a low-mobility proppant bank at or near the perforations. The effect is related to proppant scheduling and transport characteristics, not to excessive leakoff or insufficient pad volume.
