RIO DE JANEIRO Brazil's state-led Petrobras has made "one of the most significant oil discoveries" in the country's offshore sub-salt play, Joao Carlos de Luca, the chief executive of Barra Energia, a partner in the discovery, told Reuters on Monday.
Petrobras, which operates the BM-S-8 block south of Rio de Janeiro in the Santos Basin, said in a securities filing that the group's Caracará prospect has shown 400 meters of continuous and connected oil reserves with excellent porosity and permeability.
The oil is of a light grade at 31 degrees on the American Petroleum Institute (API) scale. Other partners in the discovery are Portugal's Galp Energia SGPS and Brazil's Queiroz Galvao Exploracao e Producao SA.
