PARIS -- The deployment of the Nautilus acoustic positioning and streamer steering system on the vessel Alizé has increased production levels on the first project of a mega 3D seismic program currently being acquired for PEMEX in the Gulf of Mexico, according to CGGVeritas.

The Alizé has achieved a one-day production record of 117 sq km (45 sq mi) and has exceeded production targets, the company says. The company has also deployed 12 Sercel Nautilus-Sentinel steered solid streamers, with a 12 km x 8 km x 100 m (7 mi x 5 mi x 328 ft) configuration.

The first project in the PEMEX survey program, known as Han Sur-Oeste de Tamil, covers 12,300 sq km (4,749 sq mi) in the Mexican deep waters of the Gulf of Mexico.

“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,” says Robert Brunck, chairman and CEO, CGGVeritas. “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.”
