I have a question to you HO:

Can you use CO2 on field were water injection has already been used extensively?

Imagine you have a well with a water cut close to 90%, would CO2 injection recover more oil from it? How much?

There are some significant constraints on when carbon dioxide can be used, J had some horror stories when I did the first post on this. But if the circumstances are right (and it does work under water) then you might gain another 10% of the oil. Remember that in conventional recovery you might only revoer about a third of the oil in place, and as the article I quoted points out, this gives an additional recovery you might not otherwise get.
