We are the operator of several producing fields in the Campos Basin, offshore Brazil. They include the Bijupirá and Salema fields (Shell interest 80%) and the BC-10 field (Shell interest 50%). We started production from the BC-10 Phase 2 project in October 2013, which reached peak production of 41 thousand boe/d in 2014. In 2013, we exercised our pre-emptive rights to acquire an additional 23% in the BC-10 project and in January 2014 we agreed to sell a 23% interest to Qatar Petroleum International, which returned our interest to 50%.
We operate one block in the São Francisco onshore basin area (Shell interest 60%) and operate one offshore exploration block in the Santos Basin, BM-S-54 (Shell interest 80%). We also have an interest in one offshore exploration block in the Espirito Santo basin, BM-ES-27 (Shell interest 17.5%). In November 2014, we divested our 20% interest in BM-ES-23.
We also have an 18% interest in Brazil Companhia de Gas de São Paulo (Comgás), a natural gas distribution company in the state of São Paulo.
We have a 20% interest in a 35-year PSC to develop the Libra pre-salt oil field located in the Santos Basin.
In January 2015, we reached an agreement to divest our operating interest in our deep-water production asset Bijupira Salema, pending regulatory approvals.
