Enhanced 2D Proppant- Transport Simulation: The Key To Understanding Proppant Flowback and Post-Frac Productivity

摘要

It has been assumed that along with fluid viscosity and pump rate, gravity dominates final proppant placement in hydraulic fractures. Results here, based on detailed multiphase-flow modeling, show That other factors such as slurry rheology (effect of adding proppant On slurry viscosity), fluid loss and layered fluid loss, and vertical Fracture-width variations often are more important than gravity in Controlling placement.
