Two CO/sub 2/ huff 'n' puff projects were conducted in the 4,900-ft (1495-m) Reservoir (BA) Sand Unit (4900' R(BA)SU), Timbalier Bay field, Louisiana. This reservoir is a bottomwater-drive reservoir unit a 26/sup 0/ API (0.9-g/cm/sup 3/) oil gravity and 18% primary oil recovery. Before CO/sub 2/ injection, both project wells were gas lifting more than 1,000 BFPD (160 m/sup 3//d fluid) with 99% water cuts. After CO/sub 2/ injection, the production from each well increased to 200 BOPD (32 m/sup 3//d oil). This paper discusses the CO/sub 2/ huff 'n' puff process, specific reservoir characteristics, and project evaluation.
