Abstract

: Velocity analysis of Multi-channel Seismic (MCS) data and Amplitude Versus Offset (AVO) modeling will provide an efficient way of identifying gas hydrate and free gas, and therefore the nature of the BSR. Additionally, AVO modeling will also yield controls on estimates of the hydrate concentration and free gas saturation across the BSR. In the present study we apply directivity correction for obtaining true amplitude versus offset and modeling for velocity ratio across BSRs for MCS data over Kerala-Konkan offshore basin, which leads to the probable estimates of Gas Hydrates and underlying free-gas. Initial results indicate the possible presence of free gas underlying the Gas Hydrate saturated sediments in this region.
