Abstract

The project is designed to increase recoverable petroleum reserves in the United States. The Green River Formation in Utah`s Uinta Basin contains abundant hydrocarbons that are not easily recovered by primary means. The successful Lomax Monument Butte Unit water flood will be evaluated under this contract, and based on this information, water floods will be initiated in nearby Travis and Boundary units. In 1987, Lomax Exploration Company started a water flood in the Monument Butte Unit of a Douglas Creek member of the Green River Formation. This was a low-energy, geologically heterogeneous reservoir producing a waxy crude oil. Primary production yielded about 5% of the OOIP. Due to the water flood project, total production will yield an estimated recovery of 20% OOIP. The Monument Butte Unit {number_sign}10-34 and the Travis Unit {number_sign}14A-28 were put on production the last quarter of 1992. Formation Microimaging and Magnetic Resonance Imaging logs were used to evaluate these wells as commercially productive. Through June 30, 1993, the Monument Butte {number_sign} 10-34 (11/27/92 first production) has produced 6,277 barrels of oil and 6.5 MMcf of gas and the Travis {number_sign}14A-28 (1/1/93 first production) has produced 7,717 barrels of oil and 19.9 MMcf of gas.
