Hydraulic fracture models shouldn’t be a black box. We provide a detailed technical writeup so you know what the simulator is doing and why. ResFrac implements constitutive equations for fracture transport that are valid under a wide range of conditions — with the fracture open or closed, with or without proppant, Newtonian or non-Newtonian, non-Darcy and Darcy pressure gradient, and multiphase flow.
