Thermal and capillary effects on the caprock mechanical stability at In Salah, Algeria

Thermo‐mechanical effects are important in geologic carbon storage because CO 2 will generally reach the storage formation colder than the rock, inducing thermal stresses. Capillary functions, i.e., retention and relative permeability curves, control the CO 2 plume shape, which may affect overpressure and thus, caprock stability. To analyze these thermal and capillary effects, we numerically solve non‐isothermal injection of CO 2 in deformable...
