POST STACK DEPTH MIGRATION IMPROVES SALT BODY IMAGING

Davis W. Ratcliff Amoco Production Co. Houston Proper use of post stack depth migration can improve exploration success rates in areas characterized by intrusive salt. The technique provides an accurate image of salt overhang reflections, as seen on Fig. 1, where the reflections are nearly coincident with sediment terminations. This type of image helps determine updip limits of possible reservoir sands and can help determine best possible well locations along the salt-sediment interface.
