Identification of non-flooded areas under combined recovery drive

The article reviews features of non-flooded areas identification under combined recovery drive. The material balance method, applied to define the impact of depletion on oil recovery, serves as the basis for evaluation of the flooding pattern effectiveness. The study of flooding efficiency, with consideration of depletion, enhances precision of non-flooded areas identification.
Key words: flooding efficiency, combined recovery drive, material balance method, non-flooded areas
