N2 - CO2 Supercritical Fluid Extraction (SFE) has been performed on Kushiro coal. The results showed there were slightly changes in major metal oxide due to mineral dissolution/precipitation during CO2 injection. To predict mineral dissolution/precipitation in the field scale and for long geologic period of time, numerical simulations using GMG-GEM simulator were carried out. The numerical simulation was only focused on the calcite that showed to dissolve in the near injection well area (higher pressure) as well as to precipitate at some distance from the injection well when injection of CO2 was stopped.
