Subsalt play could rekindle outlook for Gulf of Mexico

Gulf of Mexico operators are drilling two subsalt wildcats with big implications for the region's petroleum prospectivity. If successful, the Mahogany prospect on Ship Shoal Block 349 and the Mattaponi prospect on South Marsh Island Block 169 by year end could spawn a major subsalt exploration play in the gulf. Mahogany and Mattaponi could affirm the accuracy of 3D seismic technology for imaging structures at depth beneath the salt sheets. Some operators believe the gulf's subsalt potential is so great that positive results of those and other subsalt tests could give a big boost to US oil and gas reserves. Moreover, better understanding of when and how the allochthonous salt bodies migrated to their present positions could prompt earth scientists to rethink theories about the gulf's tectonic evolution. The paper discusses the timing of the migration, current subsalt drilling activities, possible subsalt tests, 3-D data processing, economic challenges, and the possible addition to reserves.
