CO-2 Injection Studied For Deepwater Heavy Oil Reservoir

Simulation of deepwater, cold heavy oil production (CHOP) using the captured carbon dioxide (CO-2-EOR) technique has been investigated as part of the Well Engineering Research Group’s unconventional oil reservoir management studies being undertaken at The Robert Gordon University (RGU) in Scotland. The modeling considered transportation of CO-2 from an onshore compression station using a 240-km subsea pipeline and injected into a heavy oil reservoir (2 km below the seabed) via a vertical injection well. A production system designed to facilitate the recovery of the heavy crude to the topside separator (2 km water depth) was connected to the reservoir. The Integrated Injec
