Abstract
Several strategies were tested and studied to find injection and production procedures that “cooptimize” oil recovery and CO2 storage. The results show that traditional reservoir engineering techniques such as injecting CO2 and water in a sequential, so-called water-alternating-gas process are not conducive to maximize CO2 stored within the reservoir. A well control process that shuts in wells producing large volumes of gas and allows shut-in wells to open as reservoir pressure increases was a successful strategy for co-optimization. This result holds for immiscible and miscible gas injection and can be improved when miscible gas injection is followed by pure CO2 injection. Combining this strategy with well-control technique produced the maximum amount of oil and simultaneously stored the most CO2 giving robust results.
