Our multiclient wide-azimuth surveys provide nearly continuous coverage across the most active portions of three major Gulf of Mexico deepwater exploration plays:
Primary exploration targets in most of these areas are at depths from 20,000 to 35,000 ft beneath a complex and highly variable allochthonous salt canopy. These areas are characterized by various structural styles and trap types, from four-way closures associated with turtle structures or salt-cored folds to three-way traps against salt keels, feeders, or welds.
Wide-azimuth acquisition is one of the primary techniques being used in Gulf of Mexico surveys. It addresses the imaging issues common to this area by recording a wider range of azimuths and offsets than conventional narrow-azimuth acquisition techniques. This acquisition technique employs
Our data processing techniques for subsalt imaging include use of reverse time migration (RTM) angle gathers for subsalt update tomography, 3D GSMP general surface multiple prediction methodology for improved attenuation of multiples, and multiazimuth tomography for construction of anisotropic velocity models.
