84 The search for a source rock for the giant Tar Sand Triangle accumulation, southeastern Utah1999-03source rock; giant Tar Sand Triangle; southeastern Utah; oil resource; heavy oil and tar; oil; Tar Sand Triangle accumulation; thermal modelingA 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...
85 Size-range analysis of diesel soot with ultra-small angle X-ray scattering2005desiel soot; ultra-small angle X-ray scattering; Carbonaceous soot; diesel fuel; soot powders; sootCarbonaceous soot produced in a small diesel engine test facility was investigated with ultra-small-angle X-ray scattering.

87 Sources and deposition of organic matter in the Monterey Formation, South-Central Coastal basins of California1987-11-02organic matter; Monterey Formation; Californial ; marine algal debrisThe abundant organic matter in the Monterey Formation is commonly considered to be derived from marine algal debris rapidly deposited in anoxic bottom water during a period of high surface plankton productivity. However, many aspects of the distribution of organic matter in the Monterey of the south...
88 State and regional control of geological carbon sequestration (Part I)2011-05state and regional control; geological carbon sequestration; hydrocarbon fuel; carbon capture; geologic sequestrationIn 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 ...
