Post waterflood CO{sub 2} miscible flood in light oil, fluvial - dominated deltaic reservoirs. Technical progress report, 4th quarter, fiscal year 1994, July 1, 1994--September 30, 1994
Production from the Port Neches project has reached a new high of 500 BOPD, as shown. Production from several wells has improved after changing WAGer and CO{sub 2} injection patterns. The WAG process appears to be effective in FDD reservoirs. The WAT process has improved the oil production rates and simultaneously decreased the CO{sub 2} production rates from wells with high GOR. Material balance calculations indicate that the reservoir pressure remained relatively flat, and a new BHP will be taken this month to verify the calculations. Total CO{sub 2} injection is averaging about 9.5 MMCFD, including 3.9 MMCFD purchased from Cardox, as shown, and the balance is recycled from the producing wells. Over 50% of the gas was produced from one well, Khun No. 33. A CO{sub 2} injection line was installed to huff-puff well Khun No. 6 that did not respond yet to CO{sub 2} injection in well Khun No. 17. After injecting a limited CO{sub 2} volume in well Khun No. 6, this will be followed by a short shut-in period, then the well will be placed on production.
