Brazilian oil and natural gas output rose 1.89% in May from April to 2.78 million barrels of oil and gas equivalent a day (boepd) as crude output from giant, new offshore fields increased, Brazil's oil agency ANP said on Thursday.
Production fell 0.5% compared with a year earlier, the ANP said in its monthly Oil and Natural Gas Production Bulletin.
Brazil's state-led oil company Petrobras remained the principal producer. It was responsible for 2 .24 million boepd, or 90% of Brazil's output in the month. The production figure does not include oil owned by Petrobras partners and produced at fields operated by Petrobras.
Anglo-Dutch oil company Shell overtook Norway's Statoil to become Brazil's No. 2 producer for the first time since March. Shell produced 34,395 boepd of Brazilian output in May.
Brazil's OGX Petroleo e Gas slipped to ninth place from eighth, being overtaken by BP Plc. OGX reached 9,042 boepd day of output 1% less than in April. BP with 9,949 barrels a day was 24% above April.
Production from the so-called sub-salt offshore fields south of Rio de Janeiro rose 4.8% to 171,300 boepd. The extra production came from the Jubarte, Lula, Caratiniga and Barracuda fields.
