Comparative study of organic rich solids present in Utah and Athabasca oil sands | 1989 | organic rich solids; Utah oil sands; Athabasca oil sands; comparative study of oil sands | The presence of humic matter modifies the hydrophilic character of some oil sand solids surfaces and thereby results in serious problems in bitumen recovery using water-based processes. In the present work the fraction enriched with humic matter was separated from the bulk of Utah oil sand solids, u... |

Comparing 10 methods for solution verification and linking to model validation | 2005-03-25 | Grid convergence; V&V process; Solution Verification; Discretized continuum; Lawrence Livermore National Laboratory; Computational analyses; Discretization; Continuum process; Finite elemental analyses | Grid convergence is often assumed as a given during computational analyses involving discretization of an assumed continuum process. In practical use of finite difference and finite element analyses, perfect grid convergence is rarely achieved or assured, and this fact must be addressed to make stat... |

Comparison of kinetic analysis of source rocks and kerogen concentrates | 1994-05-10 | Shales and kerogen concentrates from the Green River, Rundel, Ohio, Kimmeridge, and Phosphoria formations were examined by Pyromat II micropyrolysis and kinetic parameters were determined by the shift-in-Tm a x , discrete distribution, modified Friedman, and modified Coats-Redfern methods. Overall, ... | |

Comparison of methods for measuring kerogen pyrolysis rates and fitting kinetic parameters | 1987-03-23 | We determine rates of product evolution during pyrolysis of several petroleum source rocks and isolated kerogens by nonisothermal techniques, including Rock Eval pyrolysis and pyrolysis-MS/MS. The resulting data are analyzed by nonlinear regression and simpler correlation techniques in terms of disc... | |

Composition and origin of the Uinta Basin bitumens | 1963-01 | The names of the three formations of interest, from oldest to youngest, the Wasatch, Green River, and Uinta, have been used largely as facies terms to differentiate sediments which were believed to be of different age but actually were deposited simultaneously. The Wasatch is predominantly fluviatil... | |

Concentration of eastern oil shales by froth flotation | 1983 | Concentration of Eastern oil shale has been accomplished by size reduction and froth flotation techniques. The efficiency of kerogen recovery depends on the extent of size reduction (1iberation) as well as frother and promoter additions. Certain grinding aids sucli as sodium silicate and fuel oil ha... | |

Conjunctive surface and groundwater management in Utah: Implications for oil shale and oil sands development | 2011-12-31 | Unconventional fuel development; Conjunctive water use; Surface water; Groundwater; Utah; Utah water law; Oil shale; Oil sands | Unconventional fuel development will require scarce water resources. In an environment characterized by scarcity, and where most water resources are fully allocated, prospective development will require minimizing water use and seeking to use water resources in the most efficient manner. Conjunctive... |

Control of geological carbon sequestration in the western United States | 2011-05 | coal; carbon dioxide; electric utilities; carbon sequestration; sequestration; geological sequestration; climate change | In the near future, the use of coal may be legally restricted due to concerns over the effects of its combustion on atmospheric carbon dioxide concentrations. Carbon capture and geologic sequestration offer one method to reduce carbon emissions from coal and other hydrocarbon fuel. While the federal... |

Control of process aid used in hot water process for extraction of bitumen from tar sand | 1984-07-31 | Tar sand; Bitumen; Tar sand feed; Free surfactant content; Slurry; Bitumen froth recovery; Bitumen; Hot water process; Bitumen extraction; Extraction circuit | The hot water process is sensitive to the nature of the tar sand feed, which varies. An alkaline process aid, usually NaOH, is normally added to the conditioning step of the process and is needed to obtain good bitumen recovery from most tar sand feeds. The invention is based on the discovery that, ... |
