The Olympic pool is located some 12 miles northeast of the city of Wewoka, in Hughes and Okfuskee counties, Okla.
The field was discovered in July 1935. Subsequent rapid development on 10-acre spacing proved 3,500 acres productive in the Senora sand, which is found at an average depth of 1,800 ft. Primary production was by solution gas drive mechanism. By 1940, 14 years after discovery, the field had produced almost 14 million bbl of oil and then was in the stripper stage.
In that year, a pilot water flood was started which in less than one year of injection proved the floodability of the Senora sand. Additional waterflood development followed, and by 1954 the entire field was being operated under a pattern water flood.
A water supply source of some 100,000 B/D of capacity was found and developed after the original source of supply, although sufficient in quantity, proved highly corrosive. The problems encountered in developing, treating and injecting this volume of water are presented.
Production and injection history to Jan. 1, 1956, is presented to show the magnitude of the results being obtained, and the comparison of recoveries under water flood to recoveries under primary operation.
The performance thus far of the Olympic pool water flood is a testimonial for "patterned" development, modern engineering techniques, and cooperation between operators in waterflooding operations. These factors, together with favorable reservoir conditions, have contributed significantly to the high efficiency being obtained. One of the largest projects in operation, the Olympic pool water flood probably holds the record for the highest daily rate of oil production, some 15,000 bbl. By the end of 1955, seven years after the start of pilot flood operations, more oil had been produced by water flood than was produced in 14 years of primary production.
