SAO PAULO, April 6 (Reuters) - Brazil's state-controlled oil
company Petroleo Brasileiro SA has agreed to buy BP
PLC's stakes in six oil blocks in Northern Brazil, the
company said in a securities filing.
Petrobras did not disclose the value of the transaction and
said it will now own 100% of the fields. The company had already
acquired stakes owned by France's Total. Environment regulator
Ibama had denied permits to drill in the region.
