CGG: Completes Perdido Subsalt Survey for Pemex and Delivers Fast-Track Imaging

CGG Completes Perdido Subsalt Survey for Pemex and Delivers Fast-Track Imaging

Paris, France - September 26, 2017

CGG has completed ahead of schedule an 11,500 sq km wide-azimuth (WAZ) survey on behalf of Pemex in the deepwater Perdido area. This new survey has been acquired perpendicularly to existing WAZ data and the combined Imaging of this first large-scale orthogonal WAZ data set is expected to provide significantly enhanced subsalt imaging results.

A fast-track TTI RTM image for the first block of approximately 5,200 sq. km was delivered earlier than planned, helping to guide the client's drilling operations.

This landmark survey also saw the first deployment of Sercel's QuietSea(TM) next-generation Passive Acoustic Monitoring (PAM) system in the Mexican Gulf of Mexico after receiving accreditation from ASEA, Mexico's oil and gas environmental authority. The system was seamlessly integrated into the five-vessel WAZ fleet and demonstrated its reliability and ease-of-use for providing clear and accurate mammal localization information during seismic operations.

Jean-Georges Malcor, CEO, CGG, said: "Our delivery of Mexico's first orthogonal WAZ data set ahead of schedule marks another outstanding operational performance by CGG. We also demonstrated our technology edge and environmental responsibility by successfully deploying the QuietSea system on this complex multi-vessel operation."
