dc.description.abstractMounting interest in natural gas hydrates as a possible future energy source has led to increasing research into their physical properties and formation. By defining the mineral assemblage of a silt dominated gas hydrate-bearing reservoir subsampled from cores recovered from Green Canyon block 955 in the Northern Gulf of Mexico on the UT-GOM2-01 expedition, a better model of hydrate reservoir properties can be constructed. Using x-ray computed tomography, x-ray diffraction, high resolution Leica microscope images, and the Rietveld method for a semi-quantitative refinement, mineral identification yielded a sediment primarily composed of quartz, with significant proportions of alkali feldspar and carbonate, and minor amounts of amphibole, micas, and clays. Due to limitations inherent to quantitative analysis, quartz, despite being the most abundant, was underestimated by the model, and albite, a feldspar mineral, was overestimated. Subsamples with the highest quartz content came from the section of the reservoir with the highest hydrate saturation. Subsamples with the highest clay content came form the section of the reservoir with the lowest hydrate saturation. Therefore, from a mineralogical perspective, the ideal natural gas hydrate reservoir is a course-grained sediment abundant in quartz and lacking in clays. Although drilling mud intrusion of high density barite and a smectite rich bentonite gel tainted the native mineralogy and accuracy of semi-quantitative measurement, performing further XRD tests will determine the foreign background and improve both qualitative and quantitative results.en_US
