TotalEnergies announces that the Libra consortium has made the final investment decision to develop an innovative natural gas and CO2 separation and reinjection unit for the Brazilian Mero field, in which it holds a 19.3% interest.

This pilot unit, which uses pioneering high-pressure subsea separation (HISEP) technology, will separate oil from gas with a high CO2 content at seabed level, enabling the gas to be reinjected directly into the reservoir.

This technology has the potential to reduce the volume of gas sent to the FPSO at the surface, thereby reducing the intensity of greenhouse gas emissions, while increasing the field's production capacity, according to the oil & gas group.
