1 A preliminary estimate of world heavy crude oil and bitumen resourcesSince the First International Conference on the Future of Heavy Crude and Tar Sands was held in Edmonton, Alberta, Canada, in June 1979, several significant events have occurred bearing upon future development of these resources. Positive factors include the following: (1) a second conference was he...1984
2 A steamflood in a Utah tar sand, U.S.A.A steamflood experiment in the Northwest Asphalt Ridge tar sand deposit near Vernal, Utah, U.S.A. was conducted in 1980. The test utilized two concentric inverted five-spot patterns covering an area of 0.25 acres (1,012 m2). The zone tested was a 45 ft (14 m) thick sandstone in the Rimrock member of...1984
3 Characteristics of tar sand bitumen asphaltenes and the effect of asphaltenes on conversion of bitumen by hydropyrolysisAsphaltenes derived from tar sand bitumen are similar to petroleum derived asphaltenes in that the geochemical history is similar for these sources. It has been shown that tar sand bitumen possesses an unusually high average molecular weight when compared with petroleum residues of similar initial b...tar sand bitumen asphaltenes; characteristics of tar sand bitumen; effect of asphaltenes; bitumen conversion; hydropyrolysis; tar sand bitumen1979
4 Characteristics of the PR Spring Tar Sand deposit, Uinta Basin, Utah, U.S.A.The Laramie Energy Technology Center (LETC) conducted a seven-corehole drilling program in the PR Spring tar sand deposit, southeastern Uinta Basin, Utah, during the summer of 1980. Three main tar sand zones in the southwestern and west-central portion of the deposit were correlated by cross section...1984
5 Characterization of a Utah tar sand bitumenA preliminary characterization of a Utah tar sand bitumen has been made using methods developed for high boiling petroleum fractions. The characterization includes information about the major compound types which can be compared with similar data for other tar sand bitumens and, more importantly, ca...Utah tar sand bitumen; tar sand bitumen characterization; bitumen; tar sand; compound types; P. R. Spring bitumen; petroleum; recovery and processing of bitumen1976
6 Characterization of macromolecular structure elements from a Green River oil shale-(I. extracts)This paper is the first of two connected papers describing the structural details of three sections of an oil shale core taken at the Skyline 16 mine in the Utah Uinta Basin. Bitumen was extracted from the shale using methanol/toluene. Kerogen was isolated from the shale using a 9- step extraction p...macromolecular structure elements; Green River oil shale; oil shale; shale oil2013
7 Chemical evaluation of product oils from two in-situ tar sand oil recovery projectsTar sand deposits are widely distributed over the United States of America. These deposits vary from small to very large, and some of the latter may prove to be of economic significance. Curiously, virtually all of the largest known deposits occur in Utah, and this state is believed to possess reser...chemical evaluation; tar sand deposits; product oils; in-situ tar sand oil recovery projects; oil recovery; in-situ tar sand1984-02-17
8 Development of oil shale in the Green River FormationIn the last two decades, U.S. petroleum demand has increased at a rate greater than that of domestic production. Concern has been expressed on the future of the Nation's energy supply if reliance must be placed entirely on increasing imports from foreign sources of questionable dependability. A dome...oil shale development; Green River Formation; domestic energy; mineral extraction1974-07
9 Influence of chemical factors on primary processing of Utah tar sand bitumenResearch of recovery and processing technology applicable to Utah tar sands is currently in progress. Development of this hydrocarbon resource has not yet occurred, principally because of high costs associated with present recovery methods. The processing of bitumens is also expected to be relativel...chemical factors of processing tar sand bitumen; Utah tar sand bitumen; tar sand bitumen; primary peocessing of tar sand bitumen1978-01-01

11 Oil sands: Reservoir or orebody?With the advent of large-scale mining projects in the Athabasca area of Alberta, the oil industry and the mining industry have been brought together in a common cause. Each industry is contributing towards the successful exploitation of the resource but there have been differences of approach betwee...oil sands; reservoir; orebody; large-scale mining; mining; petroleum; resource potential; evaluating surface mining areas1979-06-12
12 Oil-sand and heavy-oil potential of OklahomaThere are over 300 reported occurrences of heavy oil and bitumen-impregnated rocks in the State of Oklahoma. Surface oil seeps in the southern part of the State led to the discovery of some of the giant oil fields in that area. Historical records describing the mining activity in the Tri-State area ...oil sand potential; heavy oil potential; oklahoma oil sand and heavy oil; bitumen-impregnated rocks; surface oil seeps1981-06-12
13 Pilot plant program for upgrading heavy oils by hydropyrolysisThe primary separation technique for the production of synthetic fuels from such sources as oil shale, tar sand, and black oils, produces a hydrocarbon liquid that is similar in properties to the heavier fractions of crude oil or heavy crudes. Extensive processing of these materials is required to b...synthetic fuels production; oil shale; tar sand; black oils; Coal-derived liquids1984
14 Pilot plant recovery of bitumen from oil-wet tar sandsThe world's tar sand deposits appear to be divided into two basic types, characterized by the way in which the tar and sand are associated within the ore structure. In the first, the tar or bitumen in the ore is separated from the silica sand grains by a film of water. These sands are designated wat...tar sand deposit; ore structure; bitumen; Enercor1982-02-17
15 Processing of tar sand bitumens--part 2: Catalytic cracking of Asphalt Ridge bitumenThe bitumen contained in Utah tar sands represents a significant hydrocarbon resource. Commercial development of this resource has not been realized principally because of the highly viscous nature of these materials. Viscosities of Uinta Basin, Utah bitumens are typically an order of magnitude grea...tar sand bitumen; tar sand bitumen processing; catalytic cracking; Asphalt Ridge bitumen; bitumen1977-08
16 Radio-frequency heating to recover oil from Utah tar sandsThe IITRI RF Process for tar sands consists of two steps: first, the deposit is volumetrically heated with radio frequency energy to lower the viscosity of the bitumen; and the second, the bitumen is produced by one of several petroleum recovery methods. The RF (radio frequency) heating step is acco...IITRI RF Process; Utah tar sands; oil recovery; raidio-frequency heating; heavy crude1979
17 Reservoir description of the clearwater oil sand Cold Lake, Alberta CanadaThe heavy oil accumulation at Cold Lake is part of the Lower Cretaceous heavy oil deposits that occur in a discontinuous trend in the eastern half of the western Canadian basin (Figure 30-1). This trend extends from the Peace River deposit in northwestern Alberta through Wabasca, Athabasca and south...heavy oil accumulation; heavy oil deposits; deposits found on a discontinuous trend; oil sands1981
18 Sulfur compounds in oils from the Western Canada Tar BeltSulfur compounds in the gas oil fractions from two bitumens (Athabasca oil sand and Cold Lake deposit), a heavy oil (Lloydminster) from Cretaceous reservoirs along the western Canada sedimentary basin, and a Cretaceous oil from a deep reservoir that may be mature (Medicine River) are investigated. T...sulfur compounds; oils; Western Canada Tar Belt; gas oil1976
19 The unconventional petroleum resources of CaliforniaUnconventional petroleum resources are naturallyoccurring deposits of liquid and solid hydrocarbons that have not been fully exploited due to unfavorable economics or inadequate technology.
