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.

孟加拉湾安达曼盆地的水合物储层在印度蕴藏着大量的水合物。在这项研究中，我们通过X射线衍射，拉曼光谱和扫描电子显微镜研究了安达曼盆地含天然气水合物的沉积物的矿物学行为。我们还确定了含水合物沉积物的物理性质，例如pH，TDS，TOC，盐度，电导率，水含量，密度和孔隙率。这项工作旨在分析安达曼盆地水合物占据沉积物的理化和矿物学特性。
