The May-Libby reservoir is one of several reservoirs comprising the Delhi field, Richland Parish, Louisiana. The May-Libby reservoir covers 1,362 acres, contains, 5,986 net acre-ft of oil sand, and has an average thickness of 4.4 ft. Original in place reserves had been resolved to be 8,350,000 STB of 40/sup 0/ API undersaturated crude oil. The oil viscosity at the reservoir temperature of 135/sup 0/F has been determined to be approx. 3.0 cp. From Jan. 1945, to Aug. 1953, the May-Libby reservoir produced 2,676,411 bbl of oil by solution gas drive. From Aug. 1953, to Aug. 1966, a waterflood program produced an additional 1,245,800 STB to bring the total recovery to approx. 48% 001P. The in situ combustion pilot project consists of a 40-acre, 5-spot pattern having an average thickness of 8.3 ft and encompassing 333 acre-ft. Ignition of the project began on Aug. 15, 1966. Cumulative air injection and oil production as of Jan., 1970 was 2,327 MMscf and 163,080 STB, respectively. Overall oxygen utilization efficiency has been variable with an average of 92.1%.
