摘要

Production during 1994 closely matched the July 1993 forecast submitted with the Project Management Plan. During this period, Texaco purchased an average of 4.3 MMCF/D of CO(2) from Cardox that was to inject into 3 wells. The production averaged 325 to 400 BOPD from 3 wells. This represented a 4 fold increase from the production level prior to commencing CO(2) injection. The reservoir pressure increased with CO2 injection from 2460 psi in September 1993 to an average of 2810 psi in 1994. Early CO2 breakthrough from some wells required taking corrective measures, such as alternating water and CO2 injection (WAG). This was the first time a WAG process had been applied with success in sandstone reservoirs. The 3-D seismic reservoir model indicated a need for aquifer supports in order to history match the production.
