Abstract

Seismic reflection data analysis from Andaman deep water areas shows wide spread high amplitude bottom simulating reflectors (BSR) indicating several gas hydrate accumulations in the area. The BSRs in the area show all the characteristics of a classical BSR associated with gas hydrate accumulation. Double BSRs are also observed on some of the seismic sections in the area suggesting significant changes in pressure-temperature (P-T) regime in the recent past. Mapping of BSRs in the basin depicts varying gas hydrate stability zone thickness (200
