376 Control of process aid used in hot water process for extraction of bitumen from tar sand1984-07-31Tar sand; Bitumen; Tar sand feed; Free surfactant content; Slurry; Bitumen froth recovery; Bitumen; Hot water process; Bitumen extraction; Extraction circuitThe hot water process is sensitive to the nature of the tar sand feed, which varies. An alkaline process aid, usually NaOH, is normally added to the conditioning step of the process and is needed to obtain good bitumen recovery from most tar sand feeds. The invention is based on the discovery that, ...
377 Control strategies for abandoned in situ oil shale retorts1979-04In situ oil shale retorting may result in a number of environmental impacts including degradation of local surface and groundwaters, low resource recovery and subsidence. The target of present oil shale commercialization activities is the Mahogany zone in Colorado's Piceance Creek Basin. The princip...
378 Conversion of hydrocarbon gases to liquid in the fluidized bed retort1987-06-12A free radical steady-state mechanism has been developed to explain qualitative and quantitative aspects of the generation of hydrocarbon gases in the solid-recycle fluidized bed retort. The mechanism relies on what is known about butane cracking. The 1- and 2-butyl free radicals have been studied a...

385 CRS report for Congress: Developments in oil shale2008-11-17Green River; Oil shale formation; Colorado; Utah; Wyoming; Oil; Oil shale; Diesel; Jet fuel; Department of Energy; DOE; Synthetic fuels; Petroleum; Energy Policy Act of 2005; EPAct; BLM; Oil research, development, and demonstration; RD&D; Programmatic Environmental Impact Statement; PEIS; Oil shale ...The Green River oil shale formation in Colorado, Utah, and Wyoming is estimated to hold the equivalent of 1.38 trillion barrels of oil equivalent in place. The shale is generally acknowledged as a rich potential resource; however, it has not generally proved to be economically recoverable. Thus, it ...
386 Crumb rubber dispersion in tar sand bitumen1996crumb rubber dispersion; tar sand bitumen; crumb rubber; scrap rubber; bitumen co-processingThe results from preliminary experiments of scrap rubber and bitumen co-processing aimed at preparation of a polymer-modified asphaltic product are presented. For 20 and 40 wt% rubber content in rubberized asphalt, complete rubber dispersion in the bitumen was obtained.
387 Current activity in oil production from U.S. tar sands1979-06-12Oil Production; U.S. tar sands; UNITAR; Oil shale; Tar sands; Utah; Oil recovery; Heavy oil; Gas; Hydrocarbon material; Viscous crudes; Oil deposits; Texas; California; New Mexico; KentuckyIn a 1978 paper "Important for the Future" issued by UNITAR, reference was made to a quotation from a study by Resources for the Future, entitled "Energy in the American Economy: 1850-1975," by Messrs. Schurr and Netschert. The quotation is: "Relatively simple calculations of the volume of oil shale...
388 Definition and world resources of natural bitumens1990Natural bitumens, semisolid or solid mixtures of hydrocarbons and as much as 50 percent heterocyclic compounds, are composed largely of carbon and hydrogen but have substituents of nitrogen, oxygen, sulfur, and trace metals, especially iron, nickel, and vanadium. Bitumens are soluble in organic solv...
389 Delineation of gas sands by seismic stratigraphy in the Pericocal area, Orinoco Heavy Oil Belt, Venezuela1987gas sands; seismic stratigraphy; Pericocal area; Orinoco Heavy Oil Belt; deliniation of gas sands; gas sand bodiesThe purpose of this study is to define the extent of gas sand bodies found in the Oficina Formation by well SDZ-79X, in the Pericocal area of the Orinoco Heavy Oil Belt. True amplitude processing was applied to 30 km (19 mi) of seismic survey lines in the vicinity of this well. The processing showed...
390 Demographic and socioeconomic characteristics of Salt Lake County: sub-county analysis2006-12Salt Lake County; Projections; Estimates; Aging population; Baby boom; Utah; Salt Lake Aging Services; Kennecott LandThis paper is an examination of the shifting geographic distribution of the population within Salt Lake County over time as well as an analysis of the spatial distribution of its demographic and socioeconomic characteristics. It builds on the county-level analysis included in a separate section of t...
391 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...
