Fluvial sediment in Double Creek subwatershed No. 5, Washington County, Oklahoma

Double Creek subwatershed No. 5 in Washington County, Oklahoma, is one of six detention structures within the Double Creek watershed and includes 1,530 acres (2.39 square miles). The subwatershed receives runoff from approximately 5 percent of the total area of the watershed. Most precipitation falling on subwatershed No. 5 does not flow through the reservoir. During this study approximately three-fourths (47,000 acre-feet) of the precipitation was lost by evaporation and transpiration; a small amount is lost by deep subsurface percolation. Fifty-nine percent of the total sediment load was discharged from the reservoir during four major outflow periods representing 34 percent of the outflow days. The highest percentage of runoff and sediment yield occurs from March through June. Fifty-three percent of the water discharged and 63 percent of the sediment yield occurred during this 4-month period. The average annual yield of fluvial sediment from watershed No. 5 was 607 tons per square mile, or 0.95 ton per acre. A total of 21,370 tons of fluvial sediment was transported into reservoir No. 5 and a total of 19,930 tons was deposited. Seventy-eight percent of the total fluvial sediment was deposited during the first 9.2 years, or 63 percent of time of reservoir operation. The computed trap efficiency of reservoir No. 5 was 93 percent.

A study of secondary recovery possibilities of the Hogshooter field, Washington County, Oklahoma

The Hogshooter field, located in east central Washington County, Oklahoma, was first developed during the period 1906 to 1913. The field was extended later during the period 1918 to 1922. The principal producing horizon is the Bartlesville sand, found at an average depth of 1,150 feet. To January 1, 1944, the Bartlesville sand has produced 7,566,000 barrels of oil from 5,610 productive acres and 871 oil wells. Peak production, averaging 2,025 barrels per day for the year, was attained in the year 1910. The accumulation of oil in the Bartlesville sand is not related to structure. The total recovery from the Bartlesville sand in the Hogshooter field to January 1, 1944, is estimated to represent 10.3 per cent of the original oil in place, and the total residual oil is estimated to average 11,776 barrels per acre. Widespread application of vacuum, started in 1915, has had little beneficial effect on production. Some gas-repressuring in recent years has increased recovery to a small extent. Conservatively estimated water-flood recovery possibilities are: 3,500 barrels per acre for an area consisting of 1,393 acres (4,875,000 barrels total) with a reasonable profit at the present price of crude oil, and 2,500 barrels per acre for an area of 2,248 acres (5,620,000 barrels total), with no profit indicated under existing conditions. The latter area would show a profit equal to the first-mentioned area only with an increase in price of crude oil of forty-five cents per barrel. Subsurface waters at depths of 1,400 to 1,700 feet are indicated as a satisfactory source for use in water-flooding operations.
