The Grant Canyon field is located on the east side of Railroad Valley, 8 mi south of the Eagle Springs oil field. The discovery well, Grant Canyon Unit 1, was completed by Northwest Exploration Co. on September 11, 1983, flowing 1816 BOPD from the Devonian Guilmette Dolomite. Two additional wells have been completed in the field. Cumulative oil production through April 1988 is 8,211,149 barrels of oil. During March and April 1988, wells 3 and 4 flowed an average of 6081 BOPD. For these months, well 3 average 4144 BOPD with 1935 BOPD coming from well 4. Production area appears to be 240 acres. The trap is a high fault block in the boundary fault zone that separates Railroad Valley from the Grant Range to the east. The Devonian Guilmette reservoir is an intensely fractured, vuggy dolomite with some intercrystalline porosity. The top seal is the Tertiary Valley Fill which unconformably overlies Guilmette Dolomite. The oil column is about 400 ft thick and the field apparently has an active water drive, inasmuch as the 1 Unit had to be shut-in because of water production. The oil is black, 26 degree API gty, a pour of 10 F and 0.5% sulfur. Estimated ultimate recoverable oil reserves are 13 MMBO. The adjacent Bacon Flat field is a one-well field that was completed by Northwest Exploration Co. on July 5, 1981, for 200 BOPD and 1050 BWPD from the Devonian Guilmette Limestone (5316-5332 ft). Cumulative production through April 1988 is 303,860 barrels of oil. During March 1988 the well averaged 108 BOPD plus an unreported amount of water. Estimated ultimate recoverable oil reserves are 400 MBO.
