The production of Bridas increased slightly to approximately 49,000 BOE/day. The downstream refinery maintains a high level of operation capacity and research on facilities upgrade and expansion is currently conducting.


      The company holds a 10% interest in the Libra PSC, a deepwater pre-salt project in Brazil. The oilfield is located in the Santos Basin, with a block area of about 1,550 km2 and water depth of about 2,000 meters. In 2015, a successful appraisal was made in the Libra project, which further reinforced the confidence in exploration and appraisal in the block.
