In 1964, Mene Grande Oil Co. started a fireflood in the P/sub 2-3/ Sand reservoir in the Miga field of E. Venezuela. The project has continued since that time. The original oil in place was estimated at 23.2 million bbl and 1.2 million or 5% was expected to be produced by primary depletion. To date, an additional 2.6 million bbl or more than twice the primary production has been recovered by the use of the fireflood process. The air injection rate has averaged about 10 MMcfd over the 9-yr life. The average air-oil ratio has been 11,000 cu ft/bbl, which is in very close agreement with the air-oil ratio calculated from laboratory tests to determine fuel consumption and the porosity and oil saturation of the reservoir. No serious operating problems have been encountered during the fireflood. Past performance and sweep pattern studies indicate that fireflooding could result in the production of 50% of the original oil in place; whereas, the ultimate primary recovery would be only 5%.
