The offshore platform Cidade de Ilhabela started-up this Thursday, November 20, at 5:37 a.m., in the Santos Basin pre-salt field of Sapinhoá. The new unit is part of the set of production projects scheduled for this year as outlined in the company’s 2014-2018 Business and Management Plan.
The platform Cidade de Ilhabela is an FPSO (floating production storage and offloading) vessel. Petrobras hired the consortium QGOG/SBM on March 30, 2012 to build the FPSO. The hull was converted from a tanker at the CXG shipyard, in China, while the integration of the process plant modules took place at the Brasa Shipyard, in Niterói (RJ).
The offshore platform was set up at a site where the water depth reaches 2,140 meters, some 310 km off the coast of São Paulo state. It will be able to produce up to 150 thousand barrels of oil per day (bpd), compress up to 6 million m³/day of natural gas and store 1.6 million barrels of oil. Moreover, the platform will be able to inject 180 thousand barrels of water per day. Well 3-SPS-69, the first to go into operation, has a production potential of 32 thousand bpd. The oil produced in Sapinhoá field is of excellent quality – 29° API on average – and is to be offloaded by tankers.
The portion of the gas not used for reinjection into the field will flow through the Sapinhoá-Lula-Mexilhão gas pipeline to the Monteiro Lobato Gas Treatment Unit (UTGCA) located in Caraguatatuba, on the coast of São Paulo state. FPSO Cidade de Ilhabela will be connected to nine production wells and seven injection wells. Peak of production is expected to occur in the second half of 2015.
The estimated local content for Sapinhoá field development is above 55%, higher than the 30% minimum local content stipulated by Brazil’s National Petroleum, Natural Gas and Biofuels Agency (ANP). Thirteen of the FPSO’s 18 process plant modules were built in Brazil: three at EBSE-Nuclep, in Itaguaí (RJ), and ten at the Brasa Shipyard, in Niterói (RJ).
Sapinhoá field production started in January 2013 by interconnecting well 1-SPS-55 to FPSO Cidade de São Paulo (Sapinhoá Pilot), with a production capacity of up to 120 thousand bpd.
Sapinhoá field is operated by Petrobras (45%), in partnership with BG E&P Brasil Ltda (30%) and Repsol Sinopec S.A. (25%).
