Optimum Timing for CO2-EOR After Waterflooding and Soaking Effect on Miscible CO2 Flooding in a Tight Sandstone Formation,
In continuous CO2 secondary flooding, severe viscous fingering and early CO2 breakthrough (BT) occur due to an unfavourable mobility contrast between the injected CO2 and the crude oil. The oil recovery is limited after CO2 BT, which is attributed to the gas channeling problem. In continuous CO2 …

Improvement of Carbon Dioxide EOR in Water-Wet Reservoirs by Using Active Carbonated Water
CO2 injection for enhanced oil recovery has been widely and successfully used in many oil fields. The drawbacks of conventional CO2 injection are high mobility and gravity segregation, which lead to low sweep efficiency in the reservoir. Particularly in strongly water-wet reservoirs, a significant …
