Results of detailed analyses of four cores from the Threemile Canyon Area in the p. R. Spring tar sand deposit in Utah are reported by the Bureau of Mines. The cores were obtained by the Utah Geological and Mineralogical Survey as part of a 17-corehole evaluation program in the P. R. Spring, Hill Creek, and Rim Rock tar sand deposits. Average properties of the oil zone in the Threemile Canyon areas as determined from these cores are as follows: oil saturation, 67.4 pct of pore volume; porosity, 29.2 pct; permeability before oil extraction, 133 millidarcies; and permeability after oil extraction, 2,855 millidarcies. Average net thickness of oil zone is 23.8 Ft, and average depth to the top of the oil zone is 189 ft. Work done in cooperation with the University of Wyoming.
