Shell Brasil Petróleo Ltda., a Shell Plc subsidiary, has taken the final investment decision for Gato do Mato, a deepwater project in the pre-salt area of the Santos Basin offshore Brazil.  

The Gato do Mato Consortium includes Shell (operator with a 50% stake), Ecopetrol (30%) and TotalEnergies (20%). Pré-Sal Petróleo SA will act as the manager of the production sharing contract. The consortium anticipates project startup in 2029.

The group plans to install a FPSO designed to produce up to 120,000 bbl/d of oil. The current estimated recoverable resource volume of the Gato do Mato development is 370 MMbbl.

Initial operations will involve the reinjection of natural gas for reservoir pressure support, with future optionality to export gas to onshore facilities.

The blocks are offshore Brazil from the Rio de Janeiro coast, in water depths ranging from 1,750 m to 2,050 m.
