The migration phenomena of CO2 in the porous rock sample were visualized by X-ray CT. Then the storage ability of the rock sample was analyzed as the replacement ratio determined from the X-ray CT image data. This is the fundamental study related to the CO2 geological sequestration and the understanding CO2 migration process during and after the storage is one of the most important factors. In this study, CO2 migration visualization system was newly developed and the CO2 injection test into the water saturated porous rock samples was conducted. The nominal density change due to the replacement by CO2 was visualized by X-ray CT. Here, the method to evaluate the amount of CO2 replacement in the rock sample from the X-ray CT data was introduced, and the value of Berea sandstone was estimated. From the observation of replacement process in the rock sample, anisotropy of the migration process and storage ability was clarified.
