Petrobras Commences Production at Santos Basin Pre-Salt Iracema Sul Area

Petroleo Brasileiro S.A. (Petrobras) announced Tuesday that platform Cidade de Mangaratiba went into operation today (Oct. 14) at the Santos Basin pre-salt area of Iracema Sul, in Lula field, located on block BM-S-11, offshore Brazil. The start-up of the new platform was anticipated since the original expected start-up, as provided for in the 2014-2018 Business & Management Plan, had been scheduled for Nov. 6.

The platform Cidade de Mangaratiba is an FPSO (floating production storage and offloading) type unit and it was contracted in September 2011 from the Schahin-Modec consortium. The hull of the FPSO was converted at the Cosco shipyard, in Dalian, China and the integration of the process plant modules took place at the BrasFels shipyard in Angra do Reis, Rio de Janeiro.

The platform, which is set up at a depth of 7,217 feet (2,200 meters), some 149 miles (240 kilometers) off the coast, will have the capacity to process up to 150,000 barrels of oil and 282.48 million cubic feet (8 million cubic meters) of gas per day, in addition to storing 1.6 million barrels of oil. Well 4-RJS-647, the first to be connected to the FPSO, has a production potential of over 30,000 barrels per day. The oil produced at the Iracema Sul area is of high quality and of medium density (30 degree API) and will be transported by shuttle tankers.

The Santos Basin Integrated Gas Distribution Network will distribute the portion of the gas that is not used for reinjection in the field. FPSO Cidade de Mangaratiba will be connected to eight production wells and eight injection ones over the coming months. Production is expected to peak in the first half of 2016.

The estimated local content for the development of the Iracema Sul area is 42 percent, higher than the 30 percent minimum local content specified by Brazil’s National Petroleum, Natural Gas and Biofuels Agency (ANP) for block BM-S-11. The construction and integration of the platform’s modules in Brazil involved four construction sites in Rio de Janeiro – distributed across Itaguai, Ilha do Fundao, Niteroi, Angra dos Reis – as well as Bahia.

Concession BM-S-11 is operated by Petrobras (65 percent), in partnership with BG E&P Brasil Ltda (25 percent) and Petrogal Brasil S.A. (10 percent).

Technical specifications:

  • Production capacity: 150,000 barrels per day
  • Natural gas treatment capacity: 282.48 million cubic feet (8 million cubic meters) per day
  • Storage capacity: 1.6 million barrels of oil
  • Accommodation: 150 people
  • Operating water depth: 7,217 feet (2,200 meters)
