CCS 연계 이산화탄소에 의한 오일회수증진법의 잠재력과 전망

초록

This paper provides a summary of the current status, potential opportunities, and limitations for the application of enhanced oil recovery by carbon dioxide (CO2 EOR) using CO2 captured from industrial sources. Though CO2 EOR operations have traditionally focused on maximizing oil recovery, CO2 EOR can result in effective storage. Up to 97% of the initially purchased CO2 for EOR operations can be stored at the end of injection. Anthropogenic sources are accounting for steadily increasing share of CO2 supply, currently providing 12 million metric tons per year for EOR. Since significant expansion of oil production utilizing CO2 EOR will require volumes of CO2 that cannot be met by natural sources alone, industrial sources of CO2 will need to play a critical role. Since storing CO2 in association with EOR can substantially offset the extra costs associated with CCS, it can encourage its application in the absence of other incentives for CCS deployment.
