Numerical simulations of deep geological carbon sequestration are being used to design field-scale implementations, predict their long-term performance, and evaluate associated risks. However, conventional field-scale simulators are unable to explicitly resolve the pore-scale processes that exert significant control on the migration and fate of supercritical CO2 in the subsurface. A combination of physical and numerical experiments with explicit pore-scale resolution are being performed in order to identify conditions under which continuum model approximations may fail, and to propose alternative simulation approaches that can be used in such cases.
