Estimation of seismic attenuation of gas hydrate bearing sediments from multi-channel seismic data: A case study from Krishna-Godavari offshore basin
Dewangan, P.; Mandal, R.; Jaiswal, P.; Ramprasad, T.; Sriram, G. (Elsevier, 2014)Seismic attenuation of gas hydrate bearing sediments is estimated from the multi-channel seismic data acquired in KrishnaeGodavari (KG) offshore basin in the vicinity of Site NGHP-01-10, where ~128 m of fracture-filled ... -
Fault system and thermal regime in the vicinity of site NGHP-01-10, Krishna-Godavari basin, Bay of Bengal
Dewangan, P.; Sriram, G.; Ramprasad, T.; Ramana, M.V.; Jaiswal, P. (Elsevier, 2011)Drilling/coring activities onboard JOIDES Resolution for hydrate resource estimation have confirmed gas hydrate in the continental slope of Krishna-Godavari (KG) basin, Bay of Bengal and the expedition recovered fracture ... -
Logging-while-drilling and wireline velocities: Site NGHP-01-10, Krishna-Godavari Basin, India
Jaiswal, P.; Al-Bulushi, S.; Dewangan, P. (Elsevier, 2014)At Site NGHP-01-10, Krishna-Godavari Basin, India, the downhole wireline logging tool measured higher porosity and sonic velocities in gas hydrate-bearing sediments compared to the logging-while-drilling (LWD) acquired ... -
Prediction of gas hydrate saturation throughout the seismic section in Krishna Godavari basin using multivariate linear regression and multi-layer feed forward neural network approach
Singh, Y.; Nair, R.R.; Singh, H.; Datta, P.; Jaiswal, P.; Dewangan, P.; Ramprasad, T. (Springer, 2016)Stepwise linear regression, multi-layer feed forward neural (MLFN) network method was used to predict the 2D distribution of P-wave velocity, resistivity, porosity, and gas hydrate saturation throughout seismic section ... -
Seismic characterization of hydrates in faulted, fine-grained sediments of Krishna-Godavari Basin: Full waveform inversion
Jaiswal, P.; Dewangan, P.; Ramprasad, T.; Zelt, C.A. (American Geophysical Union, 2012)In fine-grained, faulted sediments, both stratigraphic and fault-induced structural variations can simultaneously determine the gas hydrate distribution. Insights into hydrate distribution can be obtained from P wave ... -
Seismic characterization of hydrates in faulted, fine-grained sediments of Krishna-Godavari basin: Full waveform inversion.
Jaiswal, P.; Dewangan, P.; Ramprasad, T.; Zelt, C.A. (Wiley, 2012)In fine-grained, faulted sediments, both stratigraphic and fault-induced structural variations can simultaneously determine the gas hydrate distribution. Insights into hydrate distribution can be obtained from P wave ... -
Seismic characterization of hydrates in faulted, fine-grained sediments of Krishna-Godavari basin: Unified imaging
Jaiswal, P.; Dewangan, P.; Ramprasad, T.; Zelt, C.A. (American Geophysical Union, 2012)A combination of diffusion and advection in fine grained sediments can create a patchy Bottom Simulating Reflector (BSR) which has little to no apparent correlation with the overlying hydrate distribution. Using 2D seismic ...
