Project Profile
Location: 70km offshore the state of Espírito Santo, Brazil
Area: 245sq km
Reserves: 600MMbbl of heavy (17.1°API) oil
Peak production: 18,000bpd
Water Depth: 1185m-1365m
Start-up Year: Sept 2008
The Jubarte field is located 70km offshore the state of Espírito Santo, Brazil, adjoining the Coachote field. It lies at a water depth of 1,300m in the northern Campos Basin in block BC-60. Discovered in January 2001, the field is owned and operated by Petrobras. The project was Petrobras\'s largest discovery since 1996, with oil reserves estimated at 600 million barrels. The field is a pre-salt area where oil and gas deposits lie under a layer of sal, making it difficult to tap the potential.
Petrobras obtained the licence to conduct long-term tests at the field in July 2002. That year, testing started with the installation of the FPSO Seillean. Operations began in October 2002 following the drilling of well 3 ESS-110H. The well was drilled horizontally until 1,300m within the oil-bearing formation. Development of the field was planned under three stages: pilot, phase I and phase II. The commercial feasibility of the field was confirmed in December 2002 with the start of the production pilot.
The pilot phase, aimed at long duration testing, included production via 3 ESS-110H. During the testing period, the well produced 16,500 barrels of oil and 100,000m³ of natural gas a day. Oil extracted from the well was stored in FPSO Seillean to transport it to the refineries. Until January 2006 the well ESS-110 HPA produced 20,000bpd.
In May 2007, Aker was awarded two supply contracts worth US$90 million by Petrobras for a gas pipeline-end manifold to the Jubarte phase II project. In November 2009 Aker Solutions secured a US$37 million contract for supplying eight subsea boosting systems (Moho) and one emergency valve (ESDV) for the project. In June 2010, PGS was contracted to install a fibre-optic permanent seismic monitoring system at the field.
The first oil in the pre-salt layer at the Jubarte field was produced in September 2008. Production from the well was expected to be 10,000-15,000bpd; however, it produced 18,000bpd. The production enables the company to develop pre-salt reserves offshore Brazil.
