Denmark’s Maersk Supply Service and Alcatel Submarine Networks (ASN), part of Nokia, have won a contract from Petrobras for the supply and installation of a permanent reservoir monitoring (PRM) system on the Mero field in the pre-salt area of the Santos Basin, 180 km off the coast of Rio de Janeiro in Brazil.
This contract with an undisclosed value, includes the engineering, procurement, construction, installation, and operation of the PRM system.
The PRM system, based on the Optowave technology developed by ASN Norway, will be used to monitor and optimise oil production from the Mero field.
ASN will mobilise its resources and subcontractors in Europe and in Brazil to complete the engineering, manufacturing, installation and commissioning of the Mero PRM system. Maersk Supply Service will project manage, engineer and execute the offshore installation itself, operating out of its office in Brazil in Rio de Janeiro and utilising one of its I-class subsea support vessels.
Optowave PRM systems installed on other offshore fields have recorded active seismic data for many years. Once captured, the data are transferred to onshore processing centers. The images are used to characterise the reservoir and are compared over the years to assess changes in reservoir pressure and the location and movement of the fluids.
