Characteristics of tar sand bitumen asphaltenes and the effect of asphaltenes on conversion of bitumen by hydropyrolysis | Asphaltenes 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 bitumen | 1979 |

Characterization of a Utah tar sand bitumen | A 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.

Development of oil shale in the Green River Formation | In 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 extraction | 1974-07 |

Influence of chemical factors on primary processing of Utah tar sand bitumen | Research 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 bitumen | 1978-01-01 |

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 areas | 1979-06-12 |

Processing of tar sand bitumens--part 2: Catalytic cracking of Asphalt Ridge bitumen | The 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; bitumen | 1977-08 |

Radio-frequency heating to recover oil from Utah tar sands | The 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 crude | 1979 |

Sulfur compounds in oils from the Western Canada Tar Belt | Sulfur 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 oil | 1976 |
