| Outline of Final Research Achievements |
This study aims to elucidate the complex flow behavior of CO2-oil-water-mineral system for the application of CO2 geological storage technique with the combination of enhanced oil recovery (CO2-EOR). For this purpose, we developed a large scale digital rock simulator with a three-phase model. We successfully reproduced various CO2-EOR scenarios by computer simulations, which are impossible to be investigated by experimental approach. By carrying out the complex flow simulation directly on the pore-scale rock geometry, we successfully calculated the three-phase relative permeability of CO2-oil-water-mineral system. Moreover, the relationships between oil recovery factor with parameters such as interfacial tension, viscosity and wettability have been investigated.
