Improving the lower cretaceous deposits development efficiency in Western Siberia employing enhanced oil recovery

Abstract

For the eleven groups of oil deposits in terrigenous reservoirs of Western Siberia, confined to the Lower Cretaceous deposits, the most effective techniques for enhanced oil recovery were selected based on a criteria analysis, followed by the numerical modeling application in terms of the final oil recovery factor. The need for a differentiated approach when using enhanced oil recovery techniques is specified. An algorithm for replicating the results obtained in the fields that did not participate in the study based on the analogy method is presented. Keywords: enhanced oil recovery techniques; oil recovery factor; hard-to-recover reserves; analogy method; differentiation and grouping of oil deposits.
