Schlumberger Ltd. is collaborating with a subsidiary of Malaysia’s state-owned Petroliam Nasional Berhad (Petronas) on a deepwater multi-client survey in Mexico’s Campeche Basin in the southern Gulf of Mexico. The agreement would license to Petronas part of a wide-azimuth survey conducted by Schlumberger’s seismic business, WesternGeco. The project, Schlumberger said, follows the Mexican government’s decision to license offshore and onshore areas to private entities (see Daily GPI, Sept. 12). More than 80,000 square kilometers, or close to 31,000 square miles, of data have been acquired in the southern Gulf over the last 12 months, the oilfield services operator said.
