We present a practical approach to imaging structures beneath gas clouds using PS-converted waves. In this approach, we developed methods to build the migration velocity model and to perform 3D prestack Kirchhoff time migration on a PC cluster and improved the processing flow for PS-converted waves. The technique was successfully applied to a 3D/4-C marine data set acquired in August 2001 and made available to us by Kerr-McGee North Sea (UK).
