Key Impact Points:

• Innovative Subsea Technology in Brazil: TotalEnergies announces the final investment decision by the Libra Consortium to develop a natural gas and CO2 separation and reinjection facility in the Mero field, located in Brazil’s deep offshore pre-salt area.
• Pilot Unit Using HISEP® Technology: This pilot unit will utilize high-pressure subsea separation technology (HISEP®) to separate oil from CO2-rich gas at the ocean’s bottom and reinject the gas directly into the reservoir.
• Environmental and Production Benefits: The technology aims to reduce the gas sent to the topside FPSO, thereby lowering greenhouse gas emissions intensity and increasing the field’s production capacity.
• Connection to Marechal Duque de Caxias FPSO: The HISEP® unit will be linked to the Marechal Duque de Caxias FPSO (Mero 3 project), which is under construction.
• TotalEnergies’ Commitment to Innovation: The company views this technology as a key part of its strategy to develop its businesses sustainably by reducing emissions and costs.
• Mero Field Partners: Operated by Petrobras with partners including TotalEnergies, Shell Brasil, CNPC, CNOOC, and Pré-Sal Petróleo S.A (PPSA).
• TotalEnergies’ Presence in Brazil: Operating for nearly 50 years, with interests in exploration & production, gas, renewables, lubricants, chemicals, and fuel distribution.
• Renewable Energy Investments: Partnership with Casa dos Ventos to develop a 12 GW renewable energy portfolio and a network of around 240 filling stations.

TotalEnergies announces that Libra Consortium has taken the final investment decision to develop an innovative natural gas and CO2 separation and reinjection facility for the Mero field in the Brazilian deep offshore pre-salt.

This pilot unit, using a pioneer high pressure subsea separation technology (HISEP®), will separate oil from CO2-rich gas at the bottom of the ocean and reinject the gas directly into the reservoir. This technology has the potential to reduce the amount of gas sent to the topside FPSO, thus enabling to reduce the GHG emissions intensity while increasing the field production capacity.

This innovation is part of the Libra Consortium’s research and development programs. The HISEP® subsea separation pilot unit will be connected to the Marechal Duque de Caxias FPSO (Mero 3 project), which is currently under construction.

“TotalEnergies is proud to participate to the development of this new technology in the Mero field. In addition to its benefits in Brazil, it should find applications for other projects within the Company. Such innovation fits with TotalEnergies’ approach to develop its businesses while reducing its emissions and costs, to improve its competitiveness in a sustainable way“, said Namita Shah, President, OneTech at TotalEnergies.

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%).
