PARIS – Equinor has contracted Alcatel Submarine Networks (ASN) to undertake a second stage of development of a permanent reservoir monitoring (PRM) system on the Johan Sverdrup field in the Norwegian North Sea.

This will extend the system’s coverage across the entire field. It means that close to 600 km (373 mi) of seismic cables and more than 10,300 acoustic sensors will be installed across the field, using ASN’s all-optic seismic technology.

For the first time offshore Norway, the technology should be in place to optimize production in time for start-up in 4Q 2022. The seismic cables are due to be installed during 2019-2020.

At peak, Equinor aims to produce 660,000 b/d of oil, equivalent to 25% of Norway’s entire petroleum production, and the company has ambitions to recover more than 70% of the field’s resources.

Philippe Piron, president of ASN, pointed out that this was the company’s third PRM contract with Equinor in less than a year, “which demonstrates the relevance of PRM versus alternative 4D technologies.”
