Petrobras removes 133 tonnes of oil from Brazil's beaches, CEO says

State-run oil company Petroleo Brasileiro has collected 133 tonnes of oil along Brazil's northeastern shoreline, Chief Executive Roberto Castello Branco said on Tuesday, in an unexplained mystery he said was worrying.

Speaking with lawmakers, he said the company had not identified any of its own oil in its analyses.

He also said that, in order to maintain stable production, Petrobras, as the company is known, needed new reserves of 1 billion barrels per year, at a cost of $3 billion.
