Statoil Gulf of Mexico LLC signed an agreement to license a large part of the WesternGeco Campeche wide-azimuth (WAZ) deepwater multiclient seismic survey in the southern Gulf of Mexico, Schlumberger Ltd. said Dec. 21.

The license also includes collaboration with WesternGeco in the seismic processing phase.

A fleet of eight vessels is conducting the survey in the Bay of Campeche for the three-year project. The project follows the Mexican government’s opening licensing rounds to non-government companies for the first time.

Maurice Nessim, president of WesternGeco, said the Campeche has complex geology requiring WAZ to image the subsalt.
