AB: Geological storage of carbon dioxide is a one of such methods to reduce the volume of greenhouse gas emission to atmosphere. It is important for geological storage of carbon dioxide to predict the migration of CO2 during the storage. Also, leakage of CO2 is the potential problem. To estimate these problems for geological storage of carbon dioxide, several simulation codes are developed. But, fluid flow of CO2 in the aquifer is not clear. In order to grasp the some parameters of simulation code, we try to measure the some parameters for the fluid flow of CO2 at the laboratory experiment. In these laboratory experiments, Toyoura sand was used to make artificial sediment. The size of sand column was 50 mm in diameter and 200 mm in length. The vessel was first filled with water. The sand was set them in the vessel and make sand column. Next, vessel was placed with water tank. Temperature of water tank was kept the constant. After the set of vessel, super-critical CO2 was injected in the top of the vessel and water was replaced with CO2. Temperature and pressure were measured at point in the top of the column. Gas production rate from the column was also measured. Thus, we apply to grasp the irreducible water saturation and residual gas saturation for this laboratory experiment. Also, we apply to visualize the fluid flow of super-critical CO2 in the water by the packs of glass beads.
