CGG Achieves Near Real-Time Imaging for Offshore Morocco Survey

Paris, France – December 6, 2016

CGG announced today the delivery of near real-time imaging results for a 4,200 sq km BroadSeis 3D marine seismic survey acquired offshore Morocco. CGG delivered the veryfast-track (VFT) RTM PSDM volume to the client only 4 days after the last shot.

This technical feat crowned an excellent operational performance by the crew of the CGG Geo Caspian who worked in a safe, collaborative and effective partnership with the client to complete the program ahead of schedule.

Jean-Georges Malcor, CEO, CGG, said: "This exceptional achievement surpasses our record last year when we delivered 1,700 sq km of fast-track depth imaging data just 9 days after acquisition for another survey offshore Morocco for the same client. It reflects the dedication of our offshore and onshore experts to go the extra mile to deliver results that continue to exceed our clients' expectations."
