CO2 Foam: Mobility Control
- CO2 Flood
Oil recovery incremental by:
Swelling oil Decreasing oil viscosity Decreasing IFT
The above can be achieved after CO2 contact to
- il. However, its contacts might be deteriorated
due to:
Geological uncertainty Gravity segregation
- CO2 Foam Flood
Mobility control can be improved.
