Brazil’s state-owned Petrobras has entered a deal with Alcatel Submarine Networks and Maersk consortium to build and install a permanent seismic monitoring system (PSMS) in the offshore Mero Field, Santos Basin.
“The Mero PSMS project has unprecedented features in Brazil and incorporates state-of-the-art 4D seismic monitoring technology, with which seismic records obtained on different dates are used to track reservoir behaviour over time,” Petrobras said.
The company will then use the data to deepen its knowledge about the distribution of fluids in the reservoir and provide greater efficiency in the production of oil from the Mero field.
Petrobras said the contract covers the construction and installation of 400 kilometres of optical fibres, distributed over an area of approximately 200 km² on the ocean floor. The optical fibres will be connected to the FPSO Sepetiba which, in connection with Petrobras’ offices, will allow remote and instant access to the data generated by the monitoring system.
Installation of this system will start in 2024.
The unitised Mero field is operated by Petrobras (38.6%), in partnership with Shell Brasil Petróleo Ltda (19.3%), TotalEnergies EP Brasil Ltda (19.3%), CNODC Brasil Petróleo e Gás Ltda (9.65%), CNOOC Petroleum Brasil Ltda (9.65%) and Pré-Sal Petróleo S.A (PPSA) (3.5%), as the Union’s representative in the non-contracted area.
