The Cidade de Ilhabela is situated in 2140m water depth, about 310km from Sao Paulo. It is expected to have a production capacity of up to 150,000b/d, compress about 6MMcm/d of natural gas, store 1.6MMbbl and has 180,000b/d of water injection capacity.
According to Petrobras, the 3-SPS-69 has the potential to produce 32,000b/d of 29°API oil. Nine production wells and seven injection wells will be in operation and connected to the city of Ilhabela. Peak production is expected in 2H 2015.
The oil produced from Sapinhoá is high quality and of medium density (29° API). Gas not used for reinjection will be transferred to shore through the Santos basin pipeline system, flowing through the Sapinhoá-Lula-Mexilhao gas pipeline to the Monteiro Lobato gas treatment unit (UTGCA) located in Caraguatatuba.
The Sapinhoá field
Petrobras estimates that the development of the Sapinhoá field is 55% higher than the local content minimum established by the National Agency of Petroleum, Natural Gas and Biofuels of 30%.
In April 2014, Petrobras announced the third well in the field, 7-SPH-04-SPS, was in production that was brought onstream in February 2014. The well lies in Block BM-S-9 and has an estimated production potential of 26,000b/d.
Sapinhoá‘s first producing well, 1-SPS-55, was brought online in December 2013, with a potential production rate of 25,000b/d. Oil from 1-SPS-55 is 30°API.
Well 9-SPS-77 was brought online in late February with a production rate of 33,000bpd. Petrobras announced that it is producing better than estimated at a rate of 36,000b/d.
FPSOs in Sapinhoá field
The Cidade de Ilhabela is the second unit deployed to the Sapinhoá field and the fifth FPSO to have come onstream in the area. The FPSO is under a 20-year charter to operate for the Brazilian giant.
The Cidade de Ilhabelais owned and operated by a joint venture formed by SBM Offshore (62.25% ownership stake) and its partners. It arrived in Brazil’s Brasa yard from China in January 2014 for bare hull and topside integration.
Petrobras began production in the Sapinhoá field began in January 2013 from well 1-SPS-55k, using the Cidade de São Paulo FPSO. The first three wells are connected to the Cidade de São Paulo through buoyancy supported risers. It has a capacity to produce 120,000b/d and is currently at plateau production.
Petrobras operates the Sapinhoá field with a 45% interest. Partners include BG Group’s BG E&P Brasil Ltda. (30%) and Repsol Sinopec Brasil (25%).
