Innovative Subsea Technology to Separate and Reinject CO2-rich Gas into the Mero field
London, 08 January 2024, (Oilandgaspress): – 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%).
