Petrobras has been carrying out intensive exploratory efforts in the Campos Basin ring fences, seeking to selectively drill exploratory opportunities close to the already existing production infrastructure. This strategy aims at contributing to the expansion or maintenance of the production curves related to the existing projects in these areas. The Exploration, Reservoir and Production teams work in an integrated way, in order to optimize each project through the extensive application of the existing data and information, taking advantage of the available infrastructure and resources. This approach leads to better economic estimates for the remaining exploration opportunities, boosting investments and further production. Excellent exploration results have been obtained by applying this integrated approach, including recent discoveries in the Campos Basin Pre-Salt reservoirs in the Marlim (Brava), Marlim Sul (Poraquê-Alto) and Albacora (Forno) ring fences, adding significant volumes to the ongoing revitalization projects. Surrounding the ring fence areas in the Campos Basin, new play concepts and technologies have been also applied, resulting in significant discoveries, such as Tartaruga Verde and Tartaruga MestiÇa oilfields, both with expected first oil production in 2018.
