The numerical CO2 flow simulation was used to evaluate the safety injection in Gundih CCS site. The narrow range reservoir model with detailed grids was prepared. Simulation results show that the injected CO2 moves to the northwest direction along with the anticline axis and the migration of CO2 will stop after about 100 years. Injected CO2 will also not move to the location of two faults. The fluctuations of total weight of mobile, trapped and dissolved CO2 in reservoir are also analyzed and the ratio of mobile CO2 increases in the condition of high volume of total injection.
