In 1999, a 2-D/4-C data set acquired with ocean-bottom cable on Mahog-any Field, Gulf of Mexico, was distributed at the SEG-EAGE Research Workshop to test the feasibility of using converted waves to image under a salt diapir. We show and discuss results obtained by several imaging methods—some in the time domain, others in the depth domain—applied to both PP and converted-wave fields (PS, also referred to as the C-wave).

After a review of the standard time-domain approach (DMO, common conversion point or CCP binning, NMO stack, and poststack time processing), we will consider more elaborate approaches. We...
