The Uruguá field is located in the deep waters of the Santos Basin, Brazil, as part of the Concession Contract BS-500, which was acquired in Round Zero from the Agência Nacional de Petróleo, Gás Natural e Biocombustíveis (ANP).
Discovery and Production
The field was declared commercially viable in 2005, and production started in 2010.
The main reservoirs consist of Campanian-aged turbidite sandstones belonging to the Itajaí-Açu Formation, with additional gas-producing intervals in the Santonian-Turonian and Albian age reservoirs.
Field Metrics
Area: Approximately 64 km².
Wells: 9 wells are currently operational in the Uruguá field.
Oil Density: The field produces oil and condensate with an API gravity ranging from 33º to 46º.
Gas Production: The field produces non-associated gas (GNA) from the Campanian to the Turonian reservoirs.
Reserves:
Volume of Gas Initially in Place (VGIP): 24.17 billion cubic meters (bcm).
Volume of Oil Initially in Place (VOIP): 49.84 million cubic meters (m³).
Infrastructure
The development plan includes four horizontal oil wells and five gas wells directly connected to a Floating Production, Storage, and Offloading (FPSO) unit, specifically the FPSO Cidade de Santos.
The Uruguá-Mexilhão Gas Pipeline, approximately 174 km long, connects the Uruguá field to the Mexilhão Platform.
Production Capacity
As of 2020, the Uruguá field, along with the Tambaú field, produced approximately 5,000 barrels per day (bpd) of oil and 918,000 cubic meters per day of gas.
Commercial and Operational Aspects
The field is part of a potential transaction where Petrobras is selling its 100% equity interest in the Uruguá and Tambaú fields.
The transaction includes the option for the buyer to sign an oil and gas purchase and sale agreement with Petrobras, facilitating the sale of the produced hydrocarbons.
There are no local content obligations associated with this concession, as it was acquired in Round Zero.
Development and Optimization Opportunities
The field offers opportunities for enhancing production through:
Drilling wells for production from undrained reservoirs.
Optimizing scanning efficiency.
Further characterization of the subsurface using an extensive technical database.
Current Status
Operations with the FPSO Cidade de Santos began in 2010, with the full oil production capacity expected to be reached with the interconnection of additional wells.
