Abstract

Abstract:

The Indian National Gas Hydrate Program (NGHP) has conducted two drilling expeditions, discovering concentrated fracture-filling gas hydrate reservoirs and sand reservoirs, which could be the prior areas to exploit gas hydrate in the future. The successful drilling expeditions of NGHP were attributed to enormous basic geological investigations and geophysical research. This paper reviews the geophysical research on gas hydrate reservoirs on the east continental margin of India, analyzes the logic and prospect of the related research, and acquires some ideas and understandings, with a view to guide geophysical studies on gas hydrate reservoirs. First, bottom-simulating reflector and enhanced reflecting indicating fluid flow are important proxies for concentrated gas hydrate reservoirs. Second, some promising research areas are proposed, including the full waveform inversion, the anisotropic resistivity detection, controlled source electromagnetic surveying, and gas hydrate saturation estimation based on the well logs and seismic data.
