Brazil: TotalEnergies and Shell bring Mero-4 FPSO on line

RIO DE JANEIRO, May 26, 2025 – Production has begun at the Alexandre de Gusmão FPSO under the Mero-4 development phase in Brazil’s Santos Basin, the Libra Consortium said on Monday.

The Mero-4 FPSO, located 180 kilometres offshore Rio de Janeiro in 2,000 metres of water, connects 12 wells with an operational capacity of 180,000 bopd and 12 mcm (423.8 mcf) of gas compression per day. The new unit brings Mero’s total installed production to 770,000 barrels per day across four FPSOs and one early production system.

“Mero-4 is the latest example of how we are working with our partners to unlock value from world-class reservoirs, sustaining material liquids production and providing for the world’s current energy needs,” Shell upstream president Peter Costello said.

“Our Brazil portfolio features long-life assets with high flow rates, resulting in some of our most competitive barrels on both operating cost and carbon footprint.”

“The start-up of Mero-4 marks the end of the development of this world-class field -with the commissioning of four FPSOs in three years- and the start of a long-term production phase generating robust free cash flow. This is a great achievement for the Libra consortium and a major milestone for TotalEnergies in Brazil, a key growth country for our Company,” TotalEnergies president of exploration and production Nicolas Terraz said.

“With its vast resources and high productivity, the Mero field delivers low cost and low emission oil production in line with our Company strategy and contributes significantly to the achievement of our objective to grow our production by 3% per year between 2024 and 2030.”

The Mero field is part of the Libra PSC signed in December 2013 and is operated by Petrobras (38.6%), in partnership with Libra Consortium partners Shell Brasil (19.3%), TotalEnergies (19.3%), CNPC (9.65%), CNOOC (9.65%) and PPSA (3.5%) representing the government in the non-contracted area.

The consortium is focused on developing Brazil’s deepwater pre-salt reserves, with the Mero field being one of its flagship projects.
