Petrobras has started up platform P-61 in Papa Terra Field in the southern tip of Campos Basin, 110 km (68 miles) offshore Brazil, the company said in a news release.

Set up at a water depth of 1,200 m (3,937 ft), platform P-61 comprises the Papa Terra field production project, along with the FPSO vessel P-63, which went onstream Nov. 11, 2013.

Currently there are five production and six injection wells interconnected to P-63, Petrobras said. An additional five injection wells will be interconnected. Thirteen production wells will be interconnected to P-61, the well known as PPT-16, which is currently in operation, is the platform’s first well.

The production of P-61 is transferred via flexible lines to FPSO P-63, which is capable of processing 140,000 bbl/d and 1 MMcm of gas, besides being able to inject 340,000 bbl of water, according to the release. Shuttle tankers transport the oil from the field, and the surplus gas not consumed on the platforms is injected into a nearby reservoir.

The topside of P-61 was built at the Keppel Felds shipyard in Singapore. The joining of the hull and the topside was completed at the Brasfels shipyard in the city of Angra dos Reis, Rio de Janeiro.

The P-61 tension leg wellhead platform is connected to a tender-assisted drilling platform and is equipped with a drilling and well completion rig. This is the first time a platform of this type operates in Brazil, Petrobras said. The P-61 wells are of the dry completion type, that is, well control valves are located on the platform, instead of on the sea floor.

The production wells of P-63 are connected to the platform via subsea flexible pipes equipped with electric heating known as IPB (Integrated Production Bundle), and the field’s 18 production wells feature subsea centrifuge pumps.

The Papa Terra Field is operated by Petrobras (62.5%) in partnership with Chevron (37.5%).
