Abstract

The presence of gas hydrates along the Indian continental margins has been inferred mainly from bottom simulating reflection (BSR) and the gas stability zone thickness map by many scientists ( Ramna M.V. et al,2006,Rastogi A et al,1999). Gas hydrate accumulation has been established in KG basin with the help of gas hydrates related proxies inferred from multidisciplinary investigations( Ramna M.V. et al,2006) . In the present study, BSR like features are noticed during the analysis of conventional 3D seismic data of Mahanadi deep water basin. It shows huge aerial extent of the order of 250Sqkm in central part of the area. It shows all the characteristics of classical BSR such as mimicking the seafloor, cutting across the underlying and overlying dipping strata and exhibiting large amplitude but opposite polarity event with respect to sea floor reflection. The BSRs are present to specific area where there is low/depositional centre at Pleistocene level.
