Geometry of undershooting a gas cloud over a reservoir of interest. The upper diagram shows the paths taken by a selected P-wave seismic ray; scattering, because of the velocity inhomogeneity caused by the pockets of gas, result in an inability to image through the gas cloud. The lower diagram shows the path taken by one selected converted (C) wave. This ray enters the sea floor (at the top edge of the figure) as a P-wave and converts on reflection at the top of reservoir to an S-wave (dashed); because fluid content has little effect on the velocity of S-waves, this ray is not scattered, and the reservoir can be imaged using multicomponent receivers on the seafloor.
