Heavy oil production operations in Potiguar Basin, Brazil | 1987 | heavy oil production operations; heavy oil; Portiguar Basin; oil fields; oil | The Potiguar basin is located on the northeastern Brazilian coast and comprises an onshore portion with 21,500 km2 (8300 mi2) and its offshore extension (Fig. 1). In the last 4 years, many oil fields have been discovered in the onshore portion, where today's production reaches 20,000 bbl/d. The oil ... |

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... |

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... |

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... |

Prudhoe Bay--a 10 year perspective | 1980 | Prudhoe Bay field; U. S. oil field; geology summary; reservoir potential; petroleum exploration | The Prudhoe Bay field is recognized as the largest oil field in the United States. The Permian-Triassic reservoirs, estimated to contain reserves of 9.6 billion bbl of oil and 26 Tcf of gas, have overshadowed other known substantial accumulations of hydrocarbons in formations ranging in age from Mis... |

Geology and geochemistry of Santa Rosa tar sands | 1987-11-02 | Santa Rosa tar sands; tar sands; heavy oil deposits; Triassic Santa Rosa Sandstone | Heavy oil deposits 11 km (7 mi) north of the town of Santa Rosa, Guadalupe County, New Mexico, in the Triassic Santa Rosa Sandstone, were mined during the 1930s. Renewed interest in this deposit in the late 1970s so far has not resulted in exploitation because of unfavorable economics and the encroa... |

Surface tar-sand deposits in California | 1987 | surface tar-sand deposits; tar sand; surface tar sand; California; oil seeps; stratigraphy; tar sand deposit structure | Tar sand deposits and oil seeps have been known in California for more than a century and were used in the exploration for many of California's largest oil fields. Sixty deposits visited by this writer yielded 24 deposits totaling 5.27 billion barrels of oil in place and another 36 estimated at 1-2 ... |

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 ... |
