Understanding core scale and pore scale migration of CO2 will improve our ability to predict storage capacity and determine the effectiveness of solubility and capillary (residual CO2) trapping. While the theoretical underpinnings of multi-phase flow are well developed for oil and gas production, there are few, if any measurements relevant to CO2 storage in saline formations. To fill this gap, core scale and pore scale measurements of CO2 migration in sandstone are being conducted.
