Abstract
Multi-phase flow behavior consisting of supercritical CO 2 and water in sandy sediments was experimentally examined to obtain relative permeability characteristics. In order to confirm the behavior, we have carried out a numerical simulation for laboratory-scale experiment, regarding permeability characteristics of supercritical CO 2 in porous media. Experimental study and numerical analysis showed the characteristics of multiphase flow and the shapes of relative permeability curves have good agreement for these approaches. The results allow us to reproduce CO 2-water flow multi-phase behavior in practical situation of geological structure. These data and parameters can be used for risk assessment of geological storage in various situations.
