Seismic evidence of free gas migration through the gas hydrate stability zone (GHSZ) and active methane seep in Krishna-Godavari offshore basin
Gullapalli, S.; Dewangan, P.; Kumar, Aditya; Dakara, G.; Mishra, C.K. (2019)Seismic amplitude versus offset (AVO) analysis was performed on the multichannel seismic data in the vicinity of Site NGHP-01-10, where thick fracture-filled gas hydrate is reported, to understand the fluid migration in ... -
Spatial distribution of gas hydrate deposits in Krishna-Godavari offshore basin, Bay of Bengal
Mishra, C.K.; Dewangan, P.; Sriram, G.; Kumar, Aditya; Dakara, G. (2019)To delineate the occurrences of gas hydrates and free gas in the Krishna-Godavari (KG) basin, Bay of Bengal, we used 3D seismic data to construct a velocity model of high spatial density. We used an automated version of ... -
The first record of active methane (cold) seep ecosystem associated with shallow methane hydrate from the Indian EEZ
Mazumdar, A.; Dewangan, P.; Peketi, A.; Sreeram, G..; Kalpana, M.S.; Naik, G.P.; Shetty, D.; Pujari, S.; Pillutla, S.P.K.; Gaikwad, V.V; Nazareth, D.; Sangodkar, N.S.; Dakara, G.; Kumar, Aditya; Mishra, C.K.; Singha, P.; Reddy, R. (Springer India, 2019)Here we report the discovery of cold-seep ecosystem and shallow methane hydrates (2-3 mbsf) associated with methane gas flares in the water column from the Indian EEZ for the first time. The seep-sites are located in the ...
