Abstract

In this paper, a finite element model is presented to determine an interactive re- lationship between fluid flow and rock deformation in the fracture porous media within a cylindrical domain. Conservations of momentum and mass are main- tained by the coupling terms representing the influences of either the volumetric strain on the rate changes of fluid flux, or the seepage force on the induced solid displacement. The formation anisotropy is accommodated by applying the con- cept of permeability tensor, while the rock heterogeneity is demonstrated via the mixture theory in which the matrix and the fractures constitute the interacting poroelastic media.
