P083 IMPROVED SUBSALT IMAGING BY WAVE EQUATION BASED VELOCITY UPDATING 1 D. BEVC 1 M.M. FLIEDNER 1 S. CRAWLEY 1 A.M. POPOVICI 1 and B. BIONDI 2 1 3DGeo Development Inc. 465 Fairchild Dr. Suite 227 Mountain View CA 94043 USA 2 Stanford University Department of Geophysics Summary Imaging a salt body in the deep Gulf of Mexico that is characterized by rapid changes in topography and smallscale rugosity of its top surface demonstrates limitations in 3-D Kirchhoff depth migration. Common Azimuth Wave-equation sharpens the top salt image and reveals details unseen in the Kirchhoff image. This allows us to
