    On Jan. 2, Petrobras signed an agreement with FMC Technologies do Brasil, a subsidiary of TechnipFMC, to develop the HISEP technology, patented by Petrobras for the separation of oil and gas at the bottom of the ocean and the reinjection of CO²-rich gas into the reservoir.

    PARIS — TotalEnergies said the Libra Consortium has taken FID to develop a natural gas and CO2 separation and reinjection facility for the Mero Field in the Brazilian deep offshore presalt.

    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. TotalEnergies said 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 technology is part of the Libra Consortium's R&D programs. The HISEP subsea separation pilot unit will be connected to the Marechal Duque de Caxias FPSO (Mero 3 project), which is under construction.

    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%).

    Last week Petrobras awarded TechnipFMC an iEPCI contract for the Mero 3 HISEP project in the presalt Santos Basin offshore Brazil.

    Also last week, Petrobras started production through the FPSO Sepetiba at the deepwater Mero Field.
