CO2 Injection in Vacuum Field—Colorado School of Mines
The Reservoir Characterization Project (RCP) is an industry sponsored consortium whose mission Is to develop and apply 3-D and 4-D ("time-lapse"), 3-C seismology and associated technologies to improve reservoir performance and hydrocarbon recovery while reducing environmental impact. RCP-Phase VI is the multidisciplinary, 4-D, 3-C study of a pilot C02 "huff-n-puff" injection project in Vacuum field, a shallow shelf carbonate reservoir located on the Northwestern Shelf of the Permian Basin, Southeastern New Mexico.
The C02 "huff-n-puff" occurred in well CVU-97 at Vacuum Field. The initial 3-D, 3-C survey was acquired from October 28 through November 13, 1995, prior to the C02 injection which occurred from November 13-December 8. The "soak" period extended from December 8 through December 28, after which CVU-97 was returned to production. The second 3-D, 3-C survey was acquired from December 21 to December 26 during the "soak" period.
