Petrobras / Start-up of platform P-61 in Papa Terra field

Rio de Janeiro, March 16, 2015 – Petróleo Brasileiro S.A. – Petrobras announces the start-up of platform P-61 in Papa Terra field, in the southern tip of Campos Basin, 110km off the coast of Brazil and at a water depth (distance between water surface and sea floor) ranging from 400 to 1,400 meters.

Set up at a water depth of 1,200 meters, platform P-61 comprises the Papa Terra field production project, along with FPSO (floating production storage and offloading) P-63, which came into operation on November 11, 2013.

Currently there are five production and six injection wells interconnected to P-63, 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 thousand barrels per day (bpd) and 1 million cubic meters (m³) of gas, besides being able to inject 340 thousand barrels of water.

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 hull and mating operation (the joining of the hull and the topside) were completed at the Brasfels shipyard in the city of Angra dos Reis, Rio de Janeiro.

The presence of reservoirs containing oil rated between 14 and 17 API, as well as the project’s great depths, have made the development of Papa-Terra field one of Petrobras’s most complex projects, requiring the incorporation of many different innovative solutions.

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. The wells of P-61 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.

Papa Terra field is operated by Petrobras (62.5%) in partnership with Chevron (37.5%). Chevron’s participation in this field development has been important given its experience with projects of this nature.

Rio de Janeiro, March 12, 2015 – Petróleo Brasileiro S.A. – Petrobras announces the start-up of the early production system at Búzios Field, Santos Basin, on Tuesday (3/10). This will be the first large scale and longest-running production at the Transfer of Rights area and will be performed by FPSO Dynamic Producer, which is interconnected to well 2-ANP-1-RJS. Due to issues limiting gas utilization, its average production will be limited to 15 thousand barrels of oil per day.
This early system will enable Petrobras to produce for a six-month period and gather important information to enhance the field’s first permanent production system using platform P-74, which is currently in the final phase of conversion at the Inhaúma shipyard in Rio de Janeiro.

Búzios field is some 200km off the coast of Rio de Janeiro, at a water depth that ranges from 1,600 to 2,100 meters. Petrobras announced its commerciality in December of 2013.

Transfer of Rights – The Transfer of Rights is an assignment agreement signed by Petrobras with the Brazilian Federal Government to a set of Santos Basin pre-salt areas and fields. This contract, as provided by law, authorized Petrobras to carry out oil and natural gas exploration and production in these areas up to 5 billion barrels of oil equivalent (oil and gas) with related payments to the Federal Government.
