Gas hydrates in Krishna-Godavari offshore basin

Abstract

The huge demand of energy fuels in the country poses a large burden on the exchequer. Augmenting the demand with the non conventional energy fuels is becoming inevitable. Pure form of Methane from gas hydrate deposits could be a potential alternative, which prompted the scientific community world over for its exploration. The multidisciplinary investigations and drilling in Krishna-Godavari and Mahanadi offshore basins, and Andaman Sea have established the occurrence of gas hydrate in varied forms, i.e., in the fractured clay/shale formations, stratigraphically controlled clay/sand and volcanic ash etc. The KG offshore basin is one of the promising petroliferous basins of the eastern continental margin of India. This paper mainly the synthesis of published work from the gas hydrates group at NIO towards the understanding of the gas hydrate distribution in KG basin inferred from the multi disciplinary investigations.
