Production resumed from the Port Neches CO2 project on December 6, 1993, after a 75 days shut in period. Since that date production is continuing to improve on various wells that responded to CO2 injection. Current production is averaging 325 BOPD from 3 wells. This represents 4 folds increase from the production level prior to commencing CO2 injection. Texaco continue to purchase an average of 4.3 MMCF/D of CO 2 from Cardox. The reservoir pressure increased with CO 2 injection from 2460 psi in September 1993 to 3328 psi in January 1994. However, the reservoir pressure declined slightly since then to 2730 psi in March of this year because of reservoir imbalance due to downtime at the CO2 source. Currently, CO 2 is being injected in 3 wells in the reservoir including the horizontal well drilled specifically for this purpose. The well, through its 250 ft horizontal section, is capable of taking all the available CO 2 volume. However, injection rate in the well is restricted in order to distribute the CO 2 evenly in the reservoir.
