When a hydraulic fracture closes on proppant, the proppant grains embed into the fracture walls, reducing effective fracture aperture and conductivity. ResFrac allows you to account for this effect using embedment data from laboratory crush or conductivity tests.
This guide walks through how to set up proppant embedment tables in ResFrac, translating lab-measured embedment values into the input format required by the simulator. Properly calibrated embedment inputs improve the accuracy of long-term production forecasts, where fracture conductivity evolves under changing closure stress over time.
