Composition and origin of authigenic carbonates in the Krishna-Godavari and Mahanadi Basins, eastern continental margin of India
(Elsevier, 2014)The mineralogical and stable isotopic composition of authigenic carbonates from the KrishnaeGodavari (KG) and Mahanadi Basin provide a deeper insight into the processes inducing carbonate formation in the sediments of the ... -
Effect of thermal non-equilibrium, seafloor topography and fluid advection on BSR-derived geothermal gradient
(Elsevier, 2014)The seafloor and bottom simulating reflectors (BSRs) are interpreted from the 3D seismic data acquired in Krishna–Godavari (KG) offshore basin in the vicinity of sites drilled/cored during National Gas Hydrate Program ... -
Estimation of seismic attenuation of gas hydrate bearing sediments from multi-channel seismic data: A case study from Krishna-Godavari offshore basin
(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 ... -
Extensive occurrence and genesis of authigenic carbonates from Krishna-Godavari offshore basin (Bay of Bengal): Possible influence of methane hydrates occurrences.
(Indian Geophysical Union, 2014)We report here the extensive occurrences of authigenic carbonate nodules/concretions from gas hydrate bearing sediments. Bulk mineralogical compositions by X-Ray diffractometry and EDS (Energy Dispersive Spectrum) analysis ... -
Gas hydrate destabilization and methane release events in the Krishna-Godavari Basin, Bay of Bengal
(Elsevier, 2014)Methane release events have been linked to global warming, alteration of the carbon cycle and influence on biota. However, unequivocal evidence of paleomethane release events are limited. We report several negative carbon ... -
Geologic implications of gas hydrates in the offshore of India: Krishna-Godavari Basin, Mahanadi Basin, Andaman Sea, Kerala-Konkan Basin
(Elsevier, 2014)Gas hydrate resource assessments that indicate enormous global volumes of gas present within hydrate accumulations have been one of the primary driving forces behind the growing interest in gas hydrates.Gas hydrate volumetric ... -
Logging-while-drilling and wireline velocities: Site NGHP-01-10, Krishna-Godavari Basin, India
(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 ... -
Methods of gas hydrate concentration estimation with field examples
(Society of Petroleum Geophysicists, India, 2009)The presence of gas hydrates alters the bulk physical properties of the host sediments. The deviation of the physical property in the hydrated layer from the regional (hydrate-free background) trend can be used to estimate ... -
Modified effective medium model for gas hydrate bearing,clay-dominated sediments in the Krishna-Godavari Basin
(Elsevier, 2014)During NGHP-Expedition-01, well logs were obtained for gas hydrate exploration in Krishna-Godavari (KG) offshore basin. These logs coupled with a suitable rock physics model can be used to understand the interaction between ... -
Synthesis of deep multichannel seismic and high resolution sparker data: Implications for the geological environment of the Krishna–Godavari offshore, Eastern Continental Margin of India
(Elsevier, 2014)Proven hydrocarbon occurrence in the Krishna Godavari (KG) basin, a part of the Eastern Continental Margin of India initiated intense exploration activities to discern the potential hydrocarbon bearing structures/payoff ...
