TotalEnergies has announced first oil from the fourth development phase of the Mero field on the Libra block, located 180 kilometers off the coast of Rio de Janeiro, Brazil, in the pre-salt area of the Santos Basin.

Launched in August 2021, this new phase called “Mero-4” will connect 12 wells to the new Alexandre de Gusmão FPSO (Floating Production, Storage and Offloading) unit, with a production capacity of 180,000 barrels of oil per day (b/d). This project has been designed to minimize greenhouse gas emissions, with reinjection of the associated gas into the reservoir and zero routine flaring.

This startup brings Mero’s total production capacity to 770,000 b/d through five FPSOs. This will represent around 100,000 boe/d in TotalEnergies share at full capacity.

“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”, said Nicolas Terraz, President Exploration & Production of TotalEnergies. “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.”

Mero is a unitized field, operated by Petrobras (38.6%), in partnership with TotalEnergies (19.3%), Shell Brasil (19.3%), CNPC (9.65%), CNOOC (9.65%) and Pré-Sal Petróleo S.A (PPSA) (3.5%) representing the Government in the non-contracted area.

TotalEnergies has been operating in Brazil for 50 years and employs close to 4,000 people in the country. Its presence encompasses Exploration & Production, gas, renewable electricity (solar and wind), lubricants and chemicals.
TotalEnergies' Exploration & Production portfolio in the country currently includes 11 licenses, of which four are operated. In 2024, the Company’s average production in the country was 153,000 barrels of oil equivalent per day.

TotalEnergies is investing in the growth of the renewable energy segment in Brazil: in October 2022, it entered a partnership with Casa dos Ventos, Brazil's leading renewable energy player, to jointly develop a 12 GW renewable energy portfolio, including onshore wind, photovoltaic and battery storage.
