Potential natural gas hydrates resources in Indian Offshore areas
(AAPG, 2004)Large amount of multi-channel seismic reflection data was acquired by oil industry for exploration of hydrocarbon in the Indian Deepwater basins, beyond 400m isobath. These data were examined for BSRs, blanking above BSRs, ... -
Rock physics modeling of shallow marine sediments in the eastern continental margin of India
(The International Society of Offshore and Polar Engineers, 2009)Rock physics models are used to estimate the geo-technical properties such as the elastic moduli from the porosity and mineralogy datasets. If the velocity measurement is available the same rock physics model can be used ... -
Scenario of gas-charged sediments and gas hydrates in the western continental margin of India
(Indian Geophysical Union, 2002)Echosounding, high-resolution shallow seismic data were collected along track lines spaced at 20 km interval across the western continental margin of India. A detailed analysis of the underway data revealed the occurrence ... -
Seismic characterization of hydrates in faulted, fine-grained sediments of Krishna-Godavari Basin: Full waveform inversion
(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: Unified imaging
(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 ... -
Shallow geological environment of Krishna–Godavari offshore, eastern continental margin of India as inferred from the interpretation of high resolution sparker data.
(Indian Academy of Sciences, 2014)Krishna–Godavari offshore basin, a part of the eastern continental margin of India is a proven petroliferous basin. Recent drilling in this area in search of gas hydrates reveals that the upper 300 m thick Quaternary–Recent ... -
Shallow stratigraphy and gas-charged sediments in the inner shelf off Redi, west coast of India
(Cent. for Earth Sci. Stud., Cochin (India), 1997)Bathymetric, side scan sonar and seismic studies were conducted in shallow waters of 11-18 m off Redi along central west coast of India to understand the stratigraphy and structural features. Bathymetric contours suggest ... -
Velocity and AVO analysis for the investigation of gas hydrate along a profile in the western continental margin
(Springer, 2007)The occurrence of gas hydrate has been inferred from the presence of Bottom-Simulating Reflectors (BSRs) along the western continental margin of India. In this paper, we assess the spatial and vertical distribution of gas ...
