RI 4795 Water Flooding Of Oil Sands In Washington County, Okla.

This report presents pertinent data on all active water-flooding projects in Washington County, Okla., and describes in detail the operation and production history of five representative floods. The flooding of partly depleted oil-bearing sands to produce petroleum that would not be recovered by other methods is becoming increasingly important to the oil industry. In 1942, two water-flooding projects in Washington County produced 35 barrels of oil daily from 90 developed acres. In March 1951, 4,000 barrels of oil was being produced daily by the injection of 58,000 barrels of water on 19 active projects covering 1,645 acres. Several projects are being extended, and new operations are being initiated. Figure 1 shows the location of the active water-flooding projects in Washington County. The yearly oil production from Washington County increased from 1,076,000 barrels in 1948 to 1,720,000 barrels in 1950, owing principally to the effects of water flooding. To March 1951, permits to flood more than 8,000 acres in Washington County had been granted by the Oklahoma Corporation Commission.
