Description

<p>In this study, the lithological properties and gas hydrate saturations in pressure-cores recovered during the India’s National Gas Hydrate Program Expedition 02 (NGHP-02) in the Krishna–Godavari Basin (K–G Basin) off the eastern margin of India were investigated. Grain size, mineralogy, and grain density and employed scanning electron microscopy (SEM) were analyzed in these investigations. The gas hydrate saturations were estimated from P-wave velocities and gas volume measurements. The results of the pressure-core analyses confirm that natural gas hydrates can occur in silt-rich sediments, and the gas hydrate occurrence is controlled by the lithology of the sediments, especially their clay content in the NGHP- 02 pressure-core sediments.</p>
