    Abstract: In applying residual moveout correction to common offset depth migrated data, common offset depth migration is applied using the best available velocity/depth model. Post migrated parts, which are depth migrated common midpoint gathers, are saved. The post migrated parts are treated as if they were in time not depth. Normal moveout based on a constant velocity is removed. Velocity functions, time-velocity pairs, are derived for the post migrated parts with normal moveout removed using a standard velocity analysis program. Normal moveout based on these velocity functions is applied. The events on the post migrated parts are now imaged to the same depth. The corrected post migrated parts are then stacked and displayed.
