Abstract

Miscible carbon dioxide (CO 2 ) flooding has been recognized as a promising approach to enhance the recovery of oil reservoirs. However, depending on the injection strategy and rock/fluid characteristics, efficiency of the miscible CO 2 flooding varies from reservoir to reservoir. Although, many studies have been carried out to evaluate the performance of the miscible CO 2 flooding, a specific strategy which can be strictly followed for a hydrocarbon reservoir has not been established yet. The aim of this study is to assess one of Pakistan�s oil reservoirs for miscible CO 2 flooding by applying a modified screening criterion and numerical modeling. As such, the most recent miscible CO 2 screening criteria were modified, and a numerical modeling was applied on the prospective reservoir. Based on the results obtained, South oil reservoir (S3) is chosen for a detailed assessment of miscible CO 2 flooding. It was also found that implementation of CO 2 water-alternating gas (CO 2 -WAG) injection at early stages of production can increase the production life of the reservoir. © 2018, The Author(s).
