The Mahogany Previous HitsubsaltNext Hit discovery is the industry's first commercial Previous HitsubsaltNext Hit oil development in the Previous HitGulfNext Hit of Previous HitMexicoNext Hit. The field discovery is located 80 miles offshore Louisiana on Ship Shoal South Additions blocks 349/359. It is a faulted anticline overlain by allochthonous salt. The allochthonous salt has a significant impact on Previous HitsubsaltNext Hit trap formation, reservoir geometry and hydrocarbon migration. The area is characterized by multiple salt sheets. Two form a sutured canopy above Mahogany, and several older, deeper sheets are identified. Previous HitSubsaltNext Hit fairways can be interpreted by mapping relative salt-induced paleobathymetry. These deepwater sand fairways were deposited prior to allochthonous salt movement.

The discovery well tested 7256 BOPD and 7.3 MMCFD on a 32/64^Prime choke at 7063 PSI flowing tubing pressure. The primary Previous HitsubsaltTop reservoir is a critically pressured oil sand with high permeability and porosity and has tremendous deliverability. Subsequent appraisal wells suggest that high sustainable production rates can be expected, and this is confirmed by rock property studies and detailed well log analysis. Integrating this information with depth-migrated 3-D seismic and regional geology studies has yielded a more complete understanding of this dynamic petroleum system.
