Reservoir Geomechanics

A 3D elasto-plastic FEM program developed for reservoir Geomechanics simulations: Introduction and case studies

The development of yielded or failure zone due to an engineering construction is a subject of study in different disciplines. In Petroleum engineering, depletion from and injection of gas into a porous rock can cause development of a yield zone around the reservoir. Studying this phenomenon requires elasto-plastic analysis of geomaterial, in this case the porous rocks. In this study, which is a...

A Priori Error Estimates for the Numerical Solution of a Coupled Geomechanics and Reservoir Flow Model with Stress-dependent Permeability

Abstract: In this paper we consider the numerical solution of a coupled geomechanics and a stress-sensitive porous media reservoir flow model. We combine mixed finite elements for Darcy flow and Galerkin finite elements for elasticity. This work focuses on deriving convergence results for the numerical solution of this nonlinear partial differential system. We establish convergence with respect...
