ABSTRACT
This chapter introduces a coupled electrokinetic-hydromechanics computational model for CO2 geo-sequestration. The averaging theory is utilized for formulating the governing field equations. A mixed discretization scheme, based on coupling between the standard Galerkin finite element method, the extended finite element method and the level-set method, together with PetrovGalerkin method; is utilized to solve the governing equations. The standard Galerkin has been utilized to discretize the deformation and the diffusive dominant field equations, and the extended finite element method, together with the level-set and Petrov-Galerkin, have been utilized to discretize the advective dominant field equations.
