Uruguá

Uruguá Oil and Gas Project Profile

Location and Geology

• 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.
