202 Attrition and abrasion models for oil shale process modeling1991-10-25As oil shale is processed, line particles, much smaller than the original shale are created. This process is called attrition or more accurately abrasion. In this paper, models of abrasion are presented for oil shale being processed in several unit operations. Two of these unit operations, a fluidiz...
203 Development of an inclined liquid fluidized bed for tar sand processing1989-12An inclined liquid fluidized-bed reactor (ILFBR) system has been developed and successfully operated for 24 hours. Modifications to the previously tested ILFBR systems include incorporation of a oil fluidizing zone in the front of the fluid bed, an increase in the angle of the fluid bed to -12 (the ...
204 Development of Utah tar sands--a status report1977The hydrocarbon resource locked in Utah's tar sands has been estimated to be in excess of 25 billion barrels. Tar sands, known variously as oil sands, bituminous sandstone, or oil-impregnated sandstone, cannot be recovered by conventional primary or secondary petroleum recovery techniques because of...

Schurr and Netschert. The quotation is: "Relatively simple calculations of the volume of oil shale...
208 Economic evaluation of oil shale and tar sands resources located in the state of Utah: Phase 21982-10Technically accurate economic evaluation of Utah resources is essential to the future health of Utah's economy and for the sound management of Utah's lands and mineral/hydrocarbon resources. This report presents the results of the second year of research aimed at resources in the State of Utah. The ...
209 Determination of the major elements and trace metals present in bitumen from several tar sand deposits1985-01The results of the analyses of 14 tar sand samples for the concentration of major elements and trace metals are presented. Ten samples were obtained from the Uinta Basin of Utah, three from the southeastern part of Utah, and one from New Mexico. In general, the major element composition of the bitum...
210 Economic potential of state-owned lands in the Sunnyside Special Tar Sand Area Carbon County, Utah1985The Sunnyside oil-impregnated (tar sand) deposit is located in the southwestern portion of the Uinta Basin, approximately 25 miles east of Price, Utah (fig. 1). The tar sands are located in the Wasatch Formation and in the Douglas Creek Member of the Green River Formation, with up to 32 individual b...
211 Bituminous sandstones in the Uinta Basin1964The largest single deposit of bituminous sandstones in the United States is found in the Uinta Basin. This deposit along with two other well known occurrences of bituminous sandstones in the northeastern portion of the basin have proved reserves exceeding 1% billion barrels of oil. The reserve calcu...
212 Diagenetic and burial history of the Lower Permian White Rim Sandstone in the Tar Sand Triangle, Paradox Basin, southeastern Utah1995Subsurface petrologic study and burial history reconstruction of the Lower Permian White Rim Sandstone in the Tar Sand triangle on the western edge of the Paradox Basin in southeastern Utah suggest that oil migrated into White Rim reservoirs after significant burial during the early Tertiary. Primar...
213 Characterization of nickel and vanadium compounds in tar sand bitumen by petroporphyrin quantitation and size exclusion chromatography coupled with element specific detection1988-02Previously, we have examined the Ni and V in heavy crude oils, residua, and processed products by several metal speciation techniques to ascertain molecular structure and processing behavior. Two classes 01 metal compounds were found -- metallopetroporphyrins and metallo-nonporphyrins - each having ...
214 Clay-induced oil loss and alkene isomerization during oil shale retortingSunnyside (Utah) tar sand was subjected to programmed temperature pyrolysis and the volatile products were detected by tandem on-line mass spectrometry (MS/MS) in real time analyses- A heating rate of 4°C/min from room temperature to 900°C was employed. Evolution of hydrogen, light hydrocarbons, n...
