Petrobras is making “interesting discoveries” in blocks of the Campos Basin offshore Rio de Janeiro, CEO Pedro Parente said in a recent investor presentation in São Paulo. The discoveries have been in mature, company-operated fields where Petrobras has recently drilled deeper to reach the presalt layer. Parente would not give details about volumes, saying that further analysis is needed. “It is interesting because these findings happened in fields with good geological characteristics,” he said. “We need now to complete initial data from drilling with geological and geophysical studies.”
