The presence of a moving fluid in a porous rock modifies its mechanical response. Poroelasticity explains how the fluid inside the pores bears a portion of the total load supported by the rock. The remaining part of the load is supported by the elastic skeleton, which contains a laminar fluid coupled to the framework by equilibrium and continuity conditions. This work introduces an original tensorial formulation of Biot’s theory and the experimental thermo-poroelastic parameters that support the theory is solved using the Earth Science Module of COMSOL Multiphysics.
