Abstract: A method for enhanced mud gas logging includes receiving a gas stream; separating the gas stream into a first gas stream, a second gas stream, and a third gas stream; directing the first gas stream to a gas chromatography configuration including a gas chromatography column and a photoionization detector; detecting, by the photoionization detector, gas species in the first gas stream; separating, by a first separation component, water vapor from the second gas stream to produce a processed second gas stream; detecting, by a first mass spectrometer, gas species in the processed second gas stream; separating, by a second separation component, water vapor and other gas species from the third gas stream to produce a processed third gas stream; and detecting, by a second mass spectrometer, gas species in the processed third gas stream.

Abstract: Embodiments of the invention relate to methods, systems, and software for identifying and quantifying subsurface hydrogen, helium, carbon dioxide, or other fluids using multiple indicia from geophysical well logs, other wireline logging tools, or mudlogging tools.

Abstract: A method for evaluating geological hydrogen source rock in a region is provided. The method includes: collecting magnetic susceptibility data from a plurality of subsurface locations in the region; receiving geophysical survey data of the region, wherein the geophysical survey data comprises geophysical data collected from above ground; tying the magnetic susceptibility data of the plurality of subsurface locations to the geophysical survey data; generating a geologic map of igneous rock, metamorphic rock, or mafic mineral-or iron-rich sedimentary rock within the region based on the magnetic susceptibility data using a model; and determining, based on the geologic map, a target zone of the geological hydrogen source rock with a potential for hydrogen production or with the potential for hydrogen accumulation.

Abstract: Methods for identifying, evaluating, and high-grading rocks associated with past or future potential generation of hydrogen from geologic materials are provided. For example, a method for evaluating a hydrogen system within a geological source rock includes obtaining a geological sample of the geological source rock; extracting ‘mobile’ gases of the geological sample under a pressure gradient; evaluating the ‘mobile’ gases extracted from the geological sample; and quantifying a volume of hydrogen previously generated based on the ‘mobile’ gases.

Abstract: The mineralogical, chemical, magnetic, and physical properties of a rock can be used to determine the amount of hydrogen that was generated during rock alteration and the remaining amount of hydrogen generation potential. The methodologies evaluate the hydrogen generation potential of geological samples and identify natural hydrogen source rocks. The mineralogy, elemental composition, iron content and oxidation state, and other properties of a geological sample may be determined. From the determined mineralogy and other properties of the geological sample, the amount of hydrogen which the geological sample may have generated may be quantified. This method can determine the maturity of hydrogen source rocks, the potential volume of hydrogen that can be generated in other parts of a given geologic province with higher degrees of hydrogen source rock maturity, and quantify the potential remaining volume of hydrogen that can be still be generated via secondary enhanced hydrogen stimulation processes.
