The Atlanta deepwater oilfield development offshore Brazil, operated by Brava Energia, is set to receive this year's Distinguished Achievement Award from the Offshore Technology Conference (OTC). The award recognizes the project's success in overcoming significant technical challenges, including producing highly viscous, high-acidity crude from a shallow, unconsolidated reservoir in a deepwater environment of about 1,550 meters, making it the world's heaviest deepwater oilfield in operation.

Current Operations and Phase Two

Production at the Atlanta field in the Santos basin began with an early production system in May 2018. Commercial-scale output started in December 2024 with the dedicated Atlanta FPSO. The current phase two development is designed to fill this FPSO's capacity and involves a total of eight wells. Six wells are currently producing, with two additional wells scheduled for drilling in the second half of 2026. Peak production from phase two, estimated at approximately 50,000 barrels of oil per day, is expected in early 2027.

Evaluation of a Third Phase

Brava is already conducting studies for a potential third development phase at Atlanta. This evaluation aims to identify the best remaining oil pockets to add new wells when production from the existing phase two wells begins to decline. The necessity for continuous well additions stems from the field's characteristics: it produces heavy 14-degree API oil, leading to wells with a rapid initial production decline before stabilization. The company is assessing the economic viability of this potential future production. Infrastructure for expansion is available, including spare slots on the FPSO and the potential future use of subsea manifolds to connect more wells. No final investment decision has been made for phase three.

Strategic Significance and Partnerships

The OTC award highlights the project's unique strategy, implemented by independent company Brava. This involved establishing partnerships with suppliers and engaging specialists on a spot basis, achieving global excellence with a lean operational structure. Brava operates the BS-4 concession, which contains the Atlanta field, with an 80% working interest. Its partner is US private investment firm Westlawn Americas Offshore, which holds the remaining 20%. The concession also contains the smaller Olivia field, for which there are currently no development plans.
