Abstract

This review explores the multifaceted aspects of injecting COï¿¿ into depleted oil reservoirs for enhanced oil recovery (EOR) and carbon sequestration. It highlights the dual benefits of increased oil production and greenhouse gas mitigation, emphasizing the role of existing infrastructure. Key considerations include fluid phase behavior, rock-fluid interactions, geomechanical effects, and economic viability. The review also addresses long-term storage security through geochemical processes and trapping mechanisms, along with the importance of monitoring technologies and the potential impacts on reservoir rock properties. The integration of COï¿¿ EOR with CCS is presented as a synergistic approach to decarbonization.
