Post waterflood CO2 miscible flood in light oil fluvial - dominated deltaic reservoirs. Technical progress report, October 1, 1994--December 30, 1994. 1st Quarter, fiscal year 1995

摘要

Production is averaging about 450 BOPD for the quarter. The fluctuation was primarily due to a temporary shutdown of CO2 delivery and maturing of the first WAG cycle. CO2 and water injection were reversed again in order to optimize changing yields and water cuts in the producing wells. Measured BHP was close to the anticipated value. A limited CO2 volume of 120 MMCF was injected to stimulate well Kuhn No. 6 to test the Huff-Puff process, since the well did not respond to CO2 injection from the main reservoir. The well will be placed on February 1, 1995. Total CO2 injection averaged this quarter about 8.8 MMCFD, including 3.6 MMCFD purchased CO2 from Cardox. The stratigraphy of the sand deposits is also discussed.
