Evans, R D

A general mathematical model is derived which may be used to describe the fluid movement through naturally fractured reservoirs. The model treats the reservoir as a double porosity medium consisting of heterogeneous, isotropic primary rock matrix blocks and an anisotropic, heterogeneous fracture matrix system. The fractures are assumed to have a general distribution in space and orientation called the fracture matrix function to represent the statistical nature of the fractures. Simplifying assumptions are made concerning flow in the individual fractures and a hemispherical volume integration of the microscopic fracture flow equations is performed to arrive at a generalized Darcy type of equation with a symmetric permeability tensor evolving to describe the flow in the fracture matrix. For flow in the primary rock matrix blocks Darcy's law for an isotropic medium is assumed. 37 refs.
