Effect of Reservoir Heterogeneity on CO2 Flooding in Tight Oil Reservoirs

Energies, 2022
Carbon dioxide (CO2)-enhanced oil recovery (EOR) has great potential and opportunity for further development, and it is one of the vital carbon capture, utilization, and storage (CCUS) technologies. However, strong heterogeneity is one of the several challenges in developing reservoirs, especially for China’s continental tight oil reserves.
