Gas Hydrate is solid compound of mainly methane and water, considered to be a huge energy resource, is still in research mode of delineation, distribution and estimation. Here, few methods/approaches have shown for quantitative assessment of gas hydrate from seismic amplitudes. Seismic attributes like reflection strength, blanking and instantaneous frequency have been computed to identify gas-hydrates in absence of BSR (Bottom simulating reflector) or to ascertain whether a BSR is related to gas-hydrates. Constrained amplitude versus offset (AVO) coupled with rock physics modeling employed here, could be an effective way for quantification of gas-hydrates and free-gas across a BSR.
