This paper describes experimental research on two-phase flow of supercritical CO_2 and water in a porous medium. We used a magnetic resonance imaging (MRI) technique to directly visualize the distribution of supercritical CO_2 injected into a packed bed of glass beads containing water. In-situ saturation distributions were successfully visualized under the temperature and pressure conditions corresponding to the aquifers at the depth of about 800m. A new coreflood interpretation method proposed by Goodfield et al. was applied to in-situ saturation data to evaluate two-phase flows in porous media directly. We calculate darcy velocity of two-phase flows of super critical CO_2 and water in porous media.
