Atlanta, a deepwater post-salt heavy oil field in the Santos Basin offshore Brazil, has begun producing oil to its new floating production, storage, and offloading vessel (FPSO).
Brazilian independent oil company Brava Energia, formed in 2024 by the merger of 3R Petroleum and Enauta, said the FPSO Atlanta had received first oil and that the Papa Terra tension leg platform (TLP) had resumed production.
In a 31 December announcement, Brava said wells 6H and 7H had begun producing to the FPSO Atlanta. Connection of the 2H, 3H, 4H, and 5H wells should be complete by the second quarter of 2025, the operator said. On 30 December, Brava announced the National Agency of Petroleum, Natural Gas, and Biofuels (ANP) had authorized production to begin at FPSO Atlanta. First oil had previously been expected in August 2024.
The FPSO Atlanta, which arrived on site in May 2024, can produce up to 50,000 BOPD, treat 140,000 BWPD, and store up to 1.6 million bbl of oil.
The Atlanta field was discovered in 2001 with Phase I and II estimated to hold more than 165 million BOE in proven and probable reserves.
According to the operator, first oil to FPSO Atlanta marks Brava as the first independent in Brazil to develop a deepwater production system from its initial phase, meeting both the expected budget and the deadlines established for drilling the wells, installing the initial equipment, and constructing the FPSO.
In a 30 December announcement, Brava said production had resumed to the Papa Terra TLP in the Campos Basin on 27 December. Production had been shut in to allow Brava to conduct maintenance and carry out an integrity recovery campaign of the production units, which the operator said would enable better planning for the reservoir’s future expansion.
In a 26 November market notice, Brava announced it signed contracts for development operations at Atlanta in the Santos Basin and Papa Terra in the Campos Basin with work starting in the fourth quarter of 2025 and the first well connections expected the following year.
The contract for Constellation Oil Services’ Lone Star rig covers two wells in each of the Atlanta and Papa Terra fields as well as the possibility for a well in Malombe, which Brava expects to reach final investment decision in the second quarter of 2025.
Brava is also acquiring two subsea trees from OneSubsea for the Atlanta field under another contract. Finally, Brava is acquiring subsea lines and risers from Baker Hughes for the Atlanta wells, with an option for equipment for a Malombe tieback.
