Physio-chemical and mineralogical analysis of gas hydrate bearing sediments of Andaman Basin

Abstract

The hydrate reservoir of Andaman Basin in the Bay of Bengal is huge reserves of hydrates in India. In this study, we studied the mineralogical behavior of gas hydrate bearing sediments of Andaman Basin by X-ray Diffraction, Raman Spectroscopy and Scanning Electron Microscopy. We also determined the physical properties such as pH, TDS, TOC, salinity, conductivity, water content, density and porosity of the hydrate bearing sediments. This work aims to analyze the physio-chemical and mineralogical properties of hydrate occupying sediments of Andaman Basin. The physio-chemical and mineralogical analysis of hydrate bearing sediments can provide the useful data for the methane production from Andaman Basin reservoir by adjusting the natural sediment properties and can help in designing a viable technology for the commercial production of gas from the hydrates.
