Computation of gas-liquid drainage in fractured porous media recognizing fracture liquid flow

We propose a simple approach to simulate gas-oil gravity drainage process in fractured porous media by using an appropriate fracture capillary pressure curve and an expression for effective fracture liquid permeability. The effective fracture liquid permeability is approximated by fracture permeability perpendicular to fracture planes. There is no need to provide fracture relative permeabilities in our model. Numerical simulation results are in excellent agreement with experimental data.
