INCORPORATING CHEMICAL EFFECTS IN A POROTHERMOELASTIC FORMULATION AND APPLICATION TO INCLINED BOREHOLES

摘要

A poromechanics formulation for transversely isotropic chemically active poroelastic media under non-isothermal conditions is presented. The formation pore fluid is modeled as a two-species constituent comprising of the solute and the solvent. The model is applied to study the thermo-chemical effects on the stress and pore pressure distributions in the vicinity of an inclined borehole drilled in a chemically active transversely isotropic formation under non-isothermal conditions.
