Abstract: A method of producing hydrocarbon fluids with improved hydrocarbon compound properties from a subsurface organic-rich rock formation, such as an oil shale formation, is provided. The method may include the step of heating the organic-rich rock formation in situ. In accordance with the method, the heating of the organic-rich rock formation may pyrolyze at least a portion of the formation hydrocarbons, for example kerogen, to create hydrocarbon fluids. Thereafter, the hydrocarbon fluids may be produced from the formation. Hydrocarbon fluids with improved hydrocarbon compound properties are also provided.

Abstract: A method and system for heating a subsurface formation using electrical resistance heating is provided. In one aspect, two or more wellbores are provided that penetrate an interval of solid organic-rich rock within the subsurface formation. At least one fracture is established in the organic-rich rock from at least one of the wellbores, and electrically conductive material is provided in the fracture. In this way electrical communication is provided between the two or more wellbores. The electrically conductive material may include a first portion placed in contact with each of the two or more wellbores, and a second portion intermediate the two or more wellbores. The first portion has a first bulk resistivity while the second portion has a second bulk resistivity.

Abstract: A testing apparatus which is suitable for applying a stress load to a test specimen is provided. The testing apparatus may be used to simulate lithostatic stress on a test specimen, which may be, for example, a portion of a geologic formation. The testing apparatus may also be used in a method of evaluating the expected production of fluids obtainable from in situ pyrolysis of oil shale.

Abstract: A reactor for subjecting multiple reactant samples to controlled conditions with respect to pressure, temperature, and time. All individual samples in a single test run are exposed to the same temperature and pressure profiles but can be independently and selectively quenched at different times during the test run.
