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 wavefield-continuation ("wave-equation" for short) migration sharpens the top salt image and reveals details unseen in the Kirchhoff image. This allows us to pick the salt body more accurately and to improve the image of the subsalt target with the corrected velocity model.
