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... |

Modeling of asphaltenes: Assessment of sensitivity of 13C SSNMR to molecular structure | 2012 | asphaltenes; heavy oil; liquid hydrocarbon fuels; 13C SSNMR; molecular structure; refinery process | Asphaltenes are an important constituent of many oils and one of the major components in heavy oils sources for liquid hydrocarbon fuels. With light oil sources rapidly depleting, it is necessary to use alternative sources from heavy oil reservoirs. Refining these heavy oil resources presents new ch... |

California plio-miocene oils: Evidence of early generation | 1987 | plio-miocene oils; California oil; source rocks; commercial generation; LOM; hydrocarbon concentration; oil quality | Early generation of oil from Monterey and equivalent source rocks may well be the primary controlling factor on oil quality in the coastal basins of California. Commercial generation has occurred at reflectance levels as low as 0.3% R0. The wide range of chemical characteristics of these oils is com... |

Influence of biodegradation on the chemical composition of heavy oil and bitumen | 1987 | biodegredation; chemical composition of heavy oil and bitumen; heavy oil; bitumen; biodegredation of petroleum | Biodegradation of petroleum is a selective metabolism of special organic compounds by an ensemble of microorganisms. It apparently starts under aerobic conditions, which are provided in areas invaded by surfacederived, oxygen-rich formation waters. Bacteria introduced into an oil pool with meteoric ... |

Nitric oxide destruction during coal and char oxidation under pulverized-coal combustion conditions | 2004 | nitric oxide destruction; coal and char oxidation; pulverized-coal combustion; particle distribution; conversion efficiency | A modified drop-tube reactor that allows particle distribution over the reactor cross-sectional area, and oxidation of chars produced in situ, was used to study the conversion efficiency of char nitrogen to nitric oxide (aNO). The results confirm previous findings by other investigators that aNO dec... |

Stratigraphy and origin of the Moenkopi Formation (Triassic) of southeastern Utah | 1973-01 | Moenkopi Formation; stratigraphy; regional stratigraphy of southeastern Utah | In southeastern Utah, the Triassic Moenkopi Formation is composed mainly of red and yellowish-gray siltstone, sandstone, mudstone, and limestone. Continuity of individual units is one of the characteristics of this formation and provides a basic for regional correlation. For the purpose of this stud... |

FT-IR and 1H NMR characterization of the products of an ethylene inverse diffusion flame | 2006 | ethylene inverse diffusion flame products; analysis of the chemical functional groups; FT-IR and 1H NMR | Knowledge of the chemical structure of young soot and its precursors is very useful in the understanding of the paths leading to soot particle inception. This paper presents analyses of the chemical functional groups, based on FT-IR and 1H NMR spectroscopy of the products obtained in an ethylene inv... |

Importance of bitumen viscosity in the hot water processing of domestic tar sands | 1983 | bitumen viscosity; hot water processing; domestic tar sands; bitumen recovery | The separation efficiency of the hot water digestionflotation technique used for bitumen recovery from various domestic tar sands was evaluated. Bitumen viscosity was found to be the most important tar sand property in determining the success of the bitumen separation. Bitumen viscosity of the tar s... |

The search for a source rock for the giant Tar Sand Triangle accumulation, southeastern Utah | 1999-03 | source rock; giant Tar Sand Triangle; southeastern Utah; oil resource; heavy oil and tar; oil; Tar Sand Triangle accumulation; thermal modeling | A large proportion (about 36%) of the world's oil resource is contained in accumulations of heavy oil or tar. In these large deposits of degraded oil, the oil in place represents only a fraction of what was present at the time of accumulation. In many of these deposits, the source of the oil is unkn... |

Biofuels--snake oil for the twenty-first century | 2008-12-01 | Most Americans are painfully aware that our present consumption of petroleum is unsustainable. The United States has less than 5% of the world's population, but consumes 24.4% of the world's petroleum production. Only 8.5% of the world's petroleum production comes from American wells, which necessit... | |
