Shell PLC subsidiary, Shell Brasil Petróleo Ltda., has reached a final investment decision (FID) on the Gato do Mato development in Block S-M-518 of the Santos Basin presalt, offshore Brazil.
Gato do Mato is a gas-condensate discovery spanning BM-S-54 and Sul de Gato do Mato blocks, situated in water depths of 1,750-2,050 meters. The project will feature a floating production storage and offloading (FPSO) vessel designed to produce up to 120,000 barrels of oil per day (b/d).
The FPSO will be moored approximately 250 km off the Brazilian coast, with initial operations focused on reinjecting natural gas for reservoir pressure maintenance, while future phases may involve gas exports to onshore facilities.
The Gato do Mato field is expected to begin production in 2029, with estimated recoverable resources of about 370 million barrels.
Shell operates the project with a 50% stake, alongside partners Ecopetrol SA (30%) and TotalEnergies SE (20%). The Brazilian government also participates in the shared production agreement through Pré-Sal Petróleo SA.
