MASSY, FranceCGG has completed an 11,500-sq km (4,440-sq mi) wide-azimuth (WAZ) survey for PEMEX in the deepwater Perdido area of the Gulf of Mexico.

The area covered is perpendicularly adjacent to existing WAZ data and combined imaging of this first large-scale orthogonal WAZ dataset of the area should significantly enhance subsalt imaging, CGG claims.

The company delivered a fasttrack TTI RTM image for the first block of around 5,200 sq km (2,007 sq mi) ahead of schedule, assisting the client’s drilling operations.

This survey also involved the first deployment ofSercel’s QuietSea next-generation passive acoustic monitoring system in the Mexican sector, following accreditation from ASEA, Mexico’s oil and gas environmental authority.

It was integrated into the five-vessel WAZ fleet and according to CGG, demonstrated its reliability and ease of use for providing clear and accurate data on mammal localization during seismic operations.
