Petro Rio announces the signing of a contract with BP Energy do Brasil for the acquisition of a 35.7% stake in Block BM-C-30 (Wahoo field), and 60% in Block BM-C-32 (Itaipu field) , thus becoming, subject to the necessary approvals, the operator of both pre-salt fields.

The Wahoo field has the potential to produce more than 140 million barrels (100% of the field), with oil discovery in 2008, and a formation test carried out in 2010, perfectly fits PetroRio's value generation strategy. With the development of the field, the Company will form another production cluster, and will share the entire infrastructure with the Frade field (including the FPSO), thus enabling the capture of several synergies resulting in another strong and sustainable reduction of the lifting cost, always maintaining the highest standards of safety and efficiency.
