A-11 MULTI-DIRECTIONAL 3D ACQUISITION AND PROCESSING FOR SUBSALT IMAGING Abstract 1 B.VER WEST R. S. HOBBS and J. YOUNG Veritas DGC Inc. 10300 Town Park Houston TX 77072 USA 3D Pre-stack depth migration (PSDM) is commonly used for improving image quality adjacent and under complex salt bodies in the Gulf of Mexico. A study has been conducted within a mini-basin of the Garden Banks area of the Gulf of Mexico to examine the benefits of combining multi-directional datasets together through depth processing to yield the most optimum near-salt and sub-salt image. Two 3D volumes of differing vintages but similar acquisition
