Petr leo Brasileiro S.A. - Petrobras communicates that FPSO Marechal Duque de Caxias (Mero 3) has initiated production operations in the Mero field, located in the pre-salt Santos Basin. The unit has the capacity to produce up to 180,000 barrels of oil per day and compress up to 12 million cubic meters of gas daily. The FPSO unit will increase Mero's installed production capacity from 410,000 to 5,000 barrels of oil perday.

The unit is part of Mero's fourth production system and was chartered from MISC. Altogether, there will be 15 wells - 8 producer wells and 7 water and gas injection wells - interconnected to the platform through an undersea infrastructure. The FPSO Pioneiro de Libra and two definitive systems - FPSO Guanabara (Mero 1) and FPSO Sepetiba (Mero 2) - are already operating in the field.

The Marechal Duque De Caxias platform will utilize innovative technologies to decarbonize and increase production, such as HISEP, expected to be operational as of 2028. This equipment will separate oil from the gas right at the bottom of the ocean, reinjecting the CO2-rich gas into the reservoir. As a result, it will be possible to free up space in the surface gas processing plant and reduce greenhouse gases released into the atmosphere.
