Here we present a case study of improved subsalt imaging for a wide azimuth (WAZ) survey in the Mississippi Canyon/Atwater Valley area in the Gulf of Mexico. The key technologies to impact the subsalt images are: 1) WAZ acquisition, 2) True Azimuth Multiple Elimination (TAME), 3) Tilted Transverse Isotropic (TTI) model building and imaging, and 4) Reverse Time Migration (RTM) based Delayed Imaging Time (DIT) scans to update the subsalt velocities.
