Brazil's oil industry regulator ANP on Thursday asked the government to extend the concession to operate the giant Marlim offshore oil field of state-run oil company Petroleo Brasileiro SA that is scheduled to expire in 2025.

In October, Marlim, in the Campos Basin east of Rio de Janeiro, produced an average 204,000 barrels a day of oil and natural gas equivalent making it Brazil's No. 5 oil field by output, according to ANP data.
