Brazil's Barra Energia do Brasil Petróleo e Gás, which owns 10 percent of the giant Carcara offshore oil prospect, will study invoking its right of first refusal
over Petrobras' sale of its 66 percent stake in the area to
Norway's Statoil, a source with direct knowledge of the situation told Reuters on Friday.
Earlier on
Friday Petroleo Brasileiro SA, as Petrobras is known, said it agreed to sell its stake in the BM-S-8 license block, home to Carcara, to Statoil for $2.5 billion. Barra is part owned by two U.S. investment funds Riverstone Holdings LLC and First Reserve Corp.
