Gas hydrates were discovered in a mud diapir in the leased block Mississippi Canyon 798 - Gulf of Mexico, through piston coring. Subsequently, a seismic experiment was set up to investigate the dynamics behind the hydrate formation. Wide aperture seismic traveltime data obtained from the experiment have been inverted to estimate 2D P-wave velocity models of the five shot lines. The results from modeling indicate the presence of free gas in regions that show up as zones of high reflectivity on the reflection profiles. The topography of the study area suggests presence of active salt bodies, which in turn, makes it plausible for the gas in the Mississippi Canyon 798 to have deeper sources.
