(Rio de Janeiro, January 9, 2007). PETRÓLEO BRASILEIRO S/A - PETROBRAS, [Bovespa: PETR3/PETR4, NYSE: PBR/PBRA, Latibex: XPBR/XPBRA, BCBA: APBR/APBRA], a Brazilian international energy company, announces that the Cidade do Rio de Janeiro FPSO went online today, in the Espadarte field, in the Campos Basin.
The Cidade do Rio de Janeiro vessel-platform will be capable of lifting up to 100,000 barrels of oil and 2.5 million cubic meters of gas per day. Installed at a water depth of 1,350 meters, the new platform can store 1.6 million barrels of oil.
The Cidade do Rio de Janeiro is an FPSO (floating, production, storage, and offloading) unit that is 320 meters long, 54 meters wide, and 30 meters tall, corresponding to a 10-story building. The new platform is expected to reach its full production capacity during 2007. When operating at full load, it will be connected to nine underwater wells, five of which for oil and natural gas production while the other four are used for water injection.
The FPSO has several technological innovations onboard, among which a new oil-pumping system developed by the Petrobras Research Center (Cenpes). The underwater centrifuge pumping system, also known as S-BCSS, assists in lifting the oil from the field to the platform. The great advantage, compared to the traditional systems, is that it is installed externally to the well, on the sea floor, expediting pump maintenance and replacement. This technology will slash operating costs, facilitate remote intervention in the connected wells, and do away with completion rig use, one of the most expensive equipment to lease in the international market.
Contracted from MODEC International LCC, the Cidade do Rio de Janeiro FPSO will make a significant contribution to maintaining Brazilian oil self-sufficiency.
