... themselves traveling faster. Almulhim et al. (2020 ) suggests that the proppant particles experience inertia forces during the completion and have difficulties smoothly exiting through the perforations at higher Stokes numbers. The difficulty exiting through the perforation causes inequality in the proppant...
