Summary This paper discusses mobility control in the Joffre Viking field miscible CO2 flood. Since 1984, three injection strategies have been tried: water-alternating-CO2 (WACO2), continuous CO2, and simultaneous CO2 and water. The studies showed that simultaneous injection results in the best CO2 conformance. CO2-foam injection has also been investigated.
