Although secondary operations have been quite successful in the Willard Unit, a substantial amount of oil will be unrecoverable by waterflooding. A CO/sub 2/ miscible displacement project was conducted in the unit to investigate the applicability of this process for full scale improved oil recovery. The project consisted of 2 separate field tests to study the various operational and reservoir aspects of the CO/sub 2/ miscible process. A complete analysis of the pilot area has not been finalized. This project verified the concept of stratified flow in the reservoir and no significant gravity overriding of the CO/sub 2/ was observed. The pressure core project was very successful and the pilot results suggest that additional oil displacement occurred as a result of the CO/sub 2/ injection.
