A 3D wide-azimuth (WAZ) marine streamer survey was designed to image deep objectives below a complex salt structure in a deepwater area of the Gulf of Mexico. Numerous technical and logistical challenges were considered in developing the design for this survey. The final candidate designs were tested with synthetic data modeling and imaging. The final selected wide-azimuth design was used for a survey acquired over the Friesian prospect in the Gulf of Mexico. We present some of the modeling studies supporting the wide-azimuth survey design, as well as acquisition and processing results from the Friesian WAZ pilot project.
