Stress-Fluid Flow Analysis of Fractured Rocks

A variational principle is used in conjunction with the finite-element method to solve the nonlinear coupled field equations of an initial boundary value problem for flow in deformable fractured rock masses. This results in a powerful method for modeling the coupled stress and fluid flow behavior of...

Description
Summary:A variational principle is used in conjunction with the finite-element method to solve the nonlinear coupled field equations of an initial boundary value problem for flow in deformable fractured rock masses. This results in a powerful method for modeling the coupled stress and fluid flow behavior of rocks. Stress and deformation history for both solid and liquid phases, for arbitrary boundary conditions, and within complex geometrical configuration, can be determined. Direct application can be made to fluid flow problems in hydraulically fractured reservoirs and naturally fractured rocks.
