Libra Consortium announces first oil from Mero-4 in Brazil pre-salt
The Mero-4 Project commenced production safely on 24 May. The Mero field is located in the pre-salt Santos Basin offshore Brazil, about 180 km from Rio de Janeiro, in a water depth of 1,800-2,100 m.
This startup brings Mero’s total production capacity to 770,000 barrels per day through five FPSOs. Mero is a unitized field operated by the Libra Consortium, which consists of Petrobras (38.6% ownership stake), in partnership with TotalEnergies (19.3%), Shell Brasil (19.3%), CNPC (9.65%), CNOOC (9.65%) and Pré-Sal Petróleo (3.5%).
Mero-4 will be developed by the traditional deep-water pre-salt development mode, FPSO+Subsea. Twelve development wells are planned to be commissioned, including five oil producers, six water or gas alternate injectors and one convertible well. To maximize production, the wells are equipped with intelligent well completion technology, which enables the remotely switching between production and injection wells via platform.
To implement green and low carbon development, Mero-4 is also equipped with resources to operate the HISEP (High Pressure Separator), which allows underwater separation between the extracted oil and the associated gas and re-inject the gas into the reservoir. The HISEP will simultaneously boost production and reduce emission.
