401 Demographic trends affecting public education in Utah2000-11Beginning in 2004 and continuing for at least a decade, the school age population (5 to 18 year olds) in Utah will increase significantly. Throughout the 1990s, the school age population in Utah grew more slowly than did the population in general so that its share in the total population declined. T...

403 Depositional environments of oil shale in the Green River Formation, Douglas Creek Arch, Colorado and Utah1985depositional environments; oil shale; Green River Formation; Douglas Creek Arch; stratigraphyDouglas Creek arch in western Colorado and eastern Utah separates the Uinta and Piceance Creek basins. During deposition of the lower part of the Eocene Green River Formation, the arch provided a physical barrier dividing ancient Lake Uinta into two segments. As the lake expanded, the arch became a ...
404 Depositional heterogeneity and fluid flow modeling of the oil shale interval of the Upper Green River Formation, Eastern Uinta Basin, Utah2008-03-12Green River Formation; Eastern Uinta Basin; Utah; Oil shale; Sedimentology; Sequence stratigraphy; Mahogany zone; Depositional heterogeneity; Fluid flow modelingDiscussion of depositional and sequence stratigraphic characterization of the upper Green River Formation based on core and well log correlation and production modeling of the richest zone (Mahogany) based on sedimentological and other information.
405 Depositional setting and preliminary oil-shale resource potential, southwestern Uinta Basin, Utah1982Oil shale; Uinta Basin; Utah; Green River; Oil yield; Lake Uinta; Mohogany zone; Kerogen; Sheep Pass; Elko Basins; Nevada; Strawberry Structure; Strawberry ReservoirThis report characterizes the potential oil-shale resources underlying those lands west of the Green River in the southwestern Uinta Basin, Utah. The principal evaluation technique has been the calculation of oil yield from oil-well sonic and density log data available in this area. Subsurface corre...
406 Description of work elements1968-08-26Previous programs have initiated and refined the development of a Utah population model to be used in projection of future requirements of both public and private facilities, goods and services.
407 Description of work elements IV: land use model1968-08-26Previous programs have initiated and refined the development of a Utah population model to be used in projection of future requirements of both public and private facilities, goods and services. The present state population forecasts are based upon the "cohort-survival" method of analysis of birth r...
408 Design Considerations for Carbon-Free CombustionDecarbonization; Hydrogen Combustion; Carbon Dioxide; Carbon-Free Combustion; CO2 Emissions; Greenhouse Gas EmissionsCombustion of a hydrocarbon produces water and carbon dioxide. As consensus continues to build around the contributions of carbon in global client change, jurisdictions, both internationally as well as domestically, are working towards limiting formation of carbon dioxide. One way to work toward eff...
409 Determination of oil shale potential Green River Formation, Uinta Basin northeast Utah1967-11-03
410 Determination of sulfur anions in spent oil shale leachates by ion chromatography1989-07The leaching and transport of chemical constituents from spent oil shale disposal areas is an area of environmental concern at the present time. Sulfur-containing compounds are prevalent in spent oil shales and have the potential to leach into aqueous systems surrounding disposal sites. Computer mod...
411 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...
412 Development of an eastern shale oil residue as an asphalt additive: Subtask 2.51997-08-11eastern shale oil residue; asphalt additive; western shale oil-derived asphalt additive; oxidative age hardening; shale oil chemistryAn evaluation of eastern shale oil as an asphalt additive to reduce oxidative age hardening and moisture susceptibility is being conducted. An eastern shale oil residue having a viscosity of 1.30 Pa.s at 60° C (140°F) was blended with three different petroleum-derived asphalts that are known to be...
413 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 ...
414 Development of the IIT Research Institute RF heating process for in situ oil shale/tar sand fuel extraction--an overview1981-04The history and current status of development of IITRI's RF process for in situ oil shale/tar sand fuel extraction is described . A brief description of the salient features of IITRI's RF process is given, together with a review of past laboratory development activities. Activities with in IITRI's ...
415 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...
416 Developments in low NOx incineration technologiesThe overall combustion industry continues to design and develop new low NOx and ultra-low NOx technologies across many applications. In general incineration design and requirements have lagged other technologies like process heaters and boiler burners. This is due to many factors but there is new fo...
417 Developments in upgrading of bitumen by hydropyrolysis1989hydropyrolysis; upgrading bitumen; gas processingHydropyrolysis, a short residence time, moderate temperature process, has been under development at the University of Utah for more than a decade. Hydropyrolysis has been shown to produce 90+% liquid product yields from feedstocks containing more than 50% nonvolatile materials. The process results i...
418 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...
