Crystal WATS C | PGS

East Breaks & Alaminos Canyon - USA - 2009

Crystal WATS C 3D

Wide-azimuth acquisition technology with modern imaging deliverables
Website Map for Survey Crystal III
The Crystal WATS III survey is located in the Central East Breaks / Alaminos Canyon areas of the Gulf of Mexico, acquired 2009 and 2010.
This deepwater area of the Gulf of Mexico is notoriously difficult to image due to a combination of thick Oligocene shale and complex salt geometries
PGS addressed the subsalt imaging challenges in the Crystal area with state-of-the-art processing, including PGS hyperTomo® for velocity model building and anisotropic PSDM with a RTM algorithm.
