Abstract: The present disclosure is directed to assaying rock samples (e.g., core samples) for the presence of catalytically-generated gases, such as methane for example. According to one or more aspects of the present disclosure, a method for assaying a rock sample comprises sealing a carbonaceous rock sample in a container having an atmosphere and assaying for a quantity of catalytically-generated gas in the sealed container. The method may comprise generating the catalytically-generated gas in response to a catalytic reaction between the carbonaceous material in the carbonaceous rock sample and a low-valent transition metal that is present in the carbonaceous rock sample. The catalytic reaction may occur in a static atmosphere of the sealed container.

Abstract: A method of producing natural gas from a heavy hydrocarbon-containing subterranean formation includes: placing a catalyst having at least one transition metal into the formation, injecting an anoxic stimulation gas into the formation, and collecting the natural gas generated in the formation. The method may be performed outside the context of a subterranean formation under controlled conditions. Thus, a method of producing natural gas from bitumen includes: providing an anoxic mixture of heavy hydrocarbons and a catalyst having at least one transition metal, adding an anoxic stimulation gas to the mixture, and heating the mixture in the presence of the stimulation gas.

Abstract: The present invention is directed to novel assays for zero-valent transition metals. The novel assays of the present invention are generally methods or processes for quantitatively and/or qualitatively evaluating the presence of zero-valent transition metals on and/or within samples. Such assays generally involve a digestion process whereby the sample is exposed to carbon monoxide. Transition metals, if present in or on the sample and if contacted by the carbon monoxide, are extracted by the carbon monoxide as metal carbonyl species, the presence of which confirms the presence of transition metals. Such novel assays have enormous predictive power in oil and gas exploration.

Abstract: The present invention relates to assays for ascribing catalytic activity to rock samples by virtue of zero-valent transition metals potentially being present within the sample. Embodiments of the present invention are generally directed to novel assays for measuring intrinsic paleocatalytic activities (k) of sedimentary rocks for converting oil to gas and projecting the activities to the subsurface based on the measured linear relationship between ln(k) and temperature (T).
