Baleia Anã is a small oil field located in the northern Campos basin, within Petrobras' Parque das Baleias area. The field contains heavy crude in a post-salt reservoir. It is being developed via the FPSO P-58, a 180,000 b/d facility shared with other fields. Parque das Baleias is a group of seven deep and ultra deep water fields. In 2014, the ANP ruled that the fields included in Parque das Baleias should be ring-fenced together and named Jubarte. Petrobras appealed the rulling but the final decision has yet to be made.
