The development of fundamental technology is essential for the practical use of the carbon dioxide capture and storage (CCS) technology. RITE carried out the demonstration test of CO_2 injection in Nagaoka, in which 10,000 tons of CO_2 was injected, and had developed monitoring and simulation technologies. Based on the findings obtained by the test, RITE develops technologies of the safety assessment technologies in present. As the part, a sensitivity study of long term CO_2 behavior using GEM-GHG simulator was performed to investigate which parameters are effective on CO_2 behavior over 1,000 year in the simulator. We used a reservoir model of Nagaoka pilot test site as a practical example. A chemical data set was scrutinized and modified to input into GEM-GHG simulator. It was clarified that parameters such as reactive surface area and component of minerals are essential and should be obtained by laboratory experiments.
