Reservoir variations at Upper Valley field Garfield County, Utah
The Upper Valley field, Garfield County, Utah, is the only significant production found to date in the Kaiparowits Basin of S.-central Utah. Cumulative production to Jan. 9176 is 14.9 million bbl of oil from 4 distinct zones within the Triassic Timpoweap and Permian Kaibab formations. All of the reservoirs are carbonates which have been dolomitized to varying degrees and were deposited in environments ranging from supratidal to shallow marine. Significant facies variations and diagenetic alterations are present in all 4 reservoir zones and have affected distribution of porosity, permeability, and fracturing. Production has been offset along the western flank and down the southern plunge of the Upper Valley anticline by a hydrodynamic drive that appears to have created a curvilinear oil-water contact due to variation in the densities of the crude within the field. The accumulation has been further complicated by an apparent lack of hydrocarbon charge along certain portions of the structure in the main pay zone.
