The oil resources in tar sand deposits in the United States | 1982 | oil resources; tar sand deposits; tar sand oil recovery processes | This report summarizes the data available at the Laramie Energy Technology Center. An effort was made to catalogue U.S. tar sand resources, identify U.S. and state maps showing tar sand deposits, and attempt to compare tar sand oil recovery processes. A review of the available data indicated there w... |

U.S. tar sand oil recovery projects--1985 | 1985-07-31 | U. S. tar sand; oil recovery projects; tar sand resource; in situ processes | Since crude oil prices declined in the early 1980's, U.S. tar sand activities have declined to a level approximating that of the early 1970's. Twenty of the 43 reported projects are in California reservoirs containing bitumen with relatively low viscosities. Only four current or planned projects are... |

Bituminous sandstone and limestone deposits of Utah | 1963 | The significant bituminous sandstone and bituminous Limestone deposits of Utah are located within, or on the edges of, the Uinta Basin. They are all located within the boundaries of Carbon, Duchesne, and Uintah Counties. The Sunnyside deposits in Carbon County contain the greatest reserves of bitumi... | |

Gilsonite | 1961-06 | glisonite; bitumen; asphalt-based petroleum; glisonite ore | Glisonite is a black, pitch-like substance which occurs in pure form in large veins in the Tertiary sediments of the Uinta Basin. It is a homogenous petroleum substance (technically it is a predominently aromatic asphaltite) which fuses relatively easily and burns like tar. Glisonite is brittle and ... |

Influence of the geological and geochemical characteristics of heavy oils on their recovery | 1987 | oil buoyancy; heavy oils; Likouala oil field; Emeraude oil field; water washing; oil saturation; biodegradation | The migration of an oil into a trap is governed by its buoyancy, the capillary pressure, and the hydrodynamic forces. For heavy oils the buoyancy is low; therefore, they can only saturate high-permeability zones, which are also preferentially swept by steam in a steam-drive recovery operation. Howev... |

Depositional environments of oil shale in the Green River Formation, Douglas Creek Arch, Colorado and Utah | 1985 | depositional environments; oil shale; Green River Formation; Douglas Creek Arch; stratigraphy | Douglas 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 ... |

Gilsonite and related hydrocarbons of the Uinta Basin, Utah | 1949 | glisonite; hydrocarbons; Uinta Basin; kerogen; bitumen | Hydrocarbons are important in the present study for two reasons: ( 1) An understanding of their nature and origin may lead to a better understanding of the oil possibilities in the area. (2) From gilsonite, kerogen, and associated bituminous substances there may be fractionated many still-undiscover... |

Technology of the recovery of values from tar sands | 1982-08 | recovery of values; tar sand; bitumen recovery; in situ processes; thermal recovery methods; COFCAW; combination of forward combustion and water flood process; emulsion-steam drive process; nuclear stimulation; mining; processing mined tar sands; anhydrous solvent extraction process; cold water sepa... | There are two basic approaches to recovering bitumen. The tar sand may be mined and transported to a process plant where the bitumen is extracted and the sand is discharged. Alternatively the separation of bitumen from sand may be accomplished without ever moving the sand, that is, in situ. In situ ... |
