Keathley Canyon/Garden Banks - USA - 2014
Full azimuth simultaneous long offset survey illuminates deep subsalt targets
Acquisition of the PGS Triton survey began in November 2013 and was completed in Q3 2014. This high-fold, long offset, dual-sensor, broadband survey provides full azimuth (FAZ) data in the central and western planning areas of the Gulf of Mexico.
The survey covers approximately 10 000 sq. km over 390 OCS blocks in Garden Banks and Keathley Canyon – both proven hydrocarbon areas. To overcome the challenges of subsalt the Triton survey was acquired using five vessels in an ORION™ configuration, and GeoStreamer technology.
Survey modeling ensured the optimal acquisition configuration to illuminate the deep subsalt Wilcox targets north and west of the Tiber discovery in Keathley Canyon, and west of the North Platte discovery in Garden Banks. These areas have historically presented difficult imaging challenges.
