CGGVeritas Revamps 3D Vessel in Mexican Waters of GOM

CGGVeritas successfully deployed its Nautilus acoustic positioning and streamer steering system on the Alizé, one of its high-end vessels, which has dramatically increased production levels on the first project of the mega 3D seismic program currently being acquired for PEMEX in the Gulf of Mexico.

Despite severe winter weather conditions the Alizé, on its first project of the program, has achieved a one-day production record of 117 km2 and has significantly exceeded production targets. This has been supported by the deployment of 12 Sercel Nautilus-Sentinel® steered solid streamers and the fact that, with a 12 by 8-km by 100-m configuration, the Alizé is towing one of the largest areal receiver arrays in the industry.

Nautilus has dramatically reduced the infill requirements through consistent streamer separations and depth control across the entire spread.

The first project in the PEMEX survey program, known as Han Sur-Oeste de Tamil, covers a surface area of 12,300 km2 in the Mexican deep waters of the Gulf of Mexico.

Robert Brunck, Chairman and CEO, CGGVeritas, said, "The Alizé's deployment of a combination of advanced Sercel Sentinel solid streamers and Nautilus is setting a new benchmark for safer operations, quieter data and better crew efficiency. We are confident that, with the Alizé's clear competitive technological edge and our advanced imaging capabilities, we will deliver the lowest-noise and highest-quality data to best image the subsalt areas being targeted by this survey program."
