Brazil's state-controlled oil company Petroleo Brasileiro SA is making 'interesting discoveries' in blocs at the Campos basin, off the Rio de Janeiro coast, where it is drilling deeper to reach the pre-salt layer, Chief Executive Pedro Parente said on Wednesday.
Parente did not give details about the discoveries, which have been made in mature fields being operated for years by the company. Only recently Petrobras, as the oil company is known, decided to drill deeper on those fields.
