Carbon dioxide (CO2) sequestration in oil and gas reservoirs and use for enhanced oil recovery (EOR)
A.R. Kovscek, Stanford University, USA
It is frequently said that oil and gas reservoirs are likely to be the first category of geological formation where carbon dioxide (CO2) shall be injected for greenhouse gas sequestration on a large scale, if sequestration proves feasible. Carbon dioxide is injected into comparatively few reservoirs at the present time. It is estimated, however, that 80% of oil reservoirs worldwide might be suitable for CO2 injection to enhance oil recovery. Enhanced oil recovery operations with CO2 have been limited by the availability and cost of CO2, but not necessarily candidate reservoirs. ...
