Brazil’s State-controlled oil company Petroleo Brasileiro (Petrobras) said on Tuesday it had ended its activities in Africa after closing the sale of a 50% stake in Petrobras Oil & Gas BV (PO&GBV), which holds some Nigerian oil assets. Petrobras, as the company is known locally, said in a filing that it had sold the PO&GBV stake for just under $1.5-billion to Petrovida Holding, which is formed by Vitol Investment Partnership II, Africa Oil Corp and Delonex Energy.
