RIO DE JANEIRO, Feb 13 (Reuters) - Brazil's state-run oil company Petroleo Brasileiro SA PETR4.SA said on Friday that output in January increased by 13.3 percent from a year earlier as new wells come on stream.
Petrobras produced 2.84 million barrels a day of oil and equivalent natural gas a day (boepd) in Brazil and abroad in January thanks to new oil production wells put into service over the last 12 months, the company said in a statement.
January production slipped 0.6 percent from December when Petrobras produced 2.86 million barrels a day of oil and equivalent natural gas a day, a monthly record for the company.
Petrobras said the month-on-month dip was due to the decommissioning of two floating platform ships, which was compensated in part by new wells started by FPSO Mangaratiba in the Lula field of the Santos basin and the P-52 and P-62 platforms in the Roncador field of the Campos basin.
Of seven new off-shore wells working in the two basins, two are producing wells and five are injector wells, Petrobras said.
Oil production from the sub-salt layers in the Santos and Campos basins broke a new record in January, increasing by 0.5 percent from December, to reach an average 669,000 barrels a day, Petrobras said. This includes output share of its partners.
The subsalt fields now account for 28 percent of Petrobras' total oil output in Brazil.
Petrobras ended 2014 with an average daily output of 2.65 million boepd, a company record. Average 2014 daily output was 4.4 percent more than the 2013 average. (Reporting by Anthony Boadle; Editing by Bernard Orr)
