Workers at Peru's Camisea natural gas fields have called off a strike scheduled for Dec. 29 after reaching a deal on labor benefits with Argentina's Pluspetrol, the union SUTRAPPEC said Dec. 28.

The union had said that the stoppage would have halted the production of natural gas that generates about half of the country's electricity and would have also disrupted Royal Dutch Shell Plc's (NYSE: RDS.A) LNG exports.

Pluspetrol controls 27.2% of the Camisea consortium. U.S.-based Hunt Oil Co. owns a 25.2% stake and Korea-based SK Innovation owns 7.6%. Tecpetrol Corp., Sonatrach SPA and Repsol SA each have 10% stakes. Hunt also controls a 50% stake in Peru LNG, which operates a natural gas liquefaction plant.
