Exploring for hydrocarbons below salt has been, and will continue to be, a high risk/high potential business endeavor. Recent Previous HitsubsaltNext Hit discoveries have generated a tremendous interest in Previous HitsubsaltNext Hit exploration, both in the Previous HitGulfNext Hit of Previous HitMexicoNext Hit as well as in other basins around the world. The geophysical technology which has played the most significant role in the success of Previous HitsubsaltNext Hit exploration is, by far, Depth Previous HitImagingNext Hit. Depth Previous HitimagingNext Hit technology (poststack and prestack) has allowed explorationists to identify and map structural and stratigraphic features below salt that trap significant hydrocarbon accumulations.

In this paper, we discuss Previous HitsubsaltNext Hit Previous HitimagingNext Hit strategies and technology applications (3-D Time and Depth Migration) that can assist the Previous HitsubsaltNext Hit explorationist in prospect evaluation, risk assessment, well placement and field development, using the Mahogany Salt Sill Area as a calibration point. In addition to utilizing a specific "Previous HitsubsaltNext Hit" acquisition geometry, the collective processing strategy will incorporate 2-D time Previous HitimagingNext Hit, 2-D poststack depth migration 2-D prestack depth migration, wide-line profiling, 3-D time Previous HitimagingTop, 3-D poststack depth migration and "target oriented" 3-D prestack depth migration.
