Statoil and Alcatel Submarine Networks sign contract for permanent reservoir monitoring on Johan Sverdrup field

Paris, France, January 17, 2018

A digital enabler to boost oil recovery, the significant data generated by this system is considered a key input to enable Statoil to deliver on its digital roadmap for the field.

Statoil and Alcatel Submarine Networks (ASN) have signed a contract for the delivery of a permanent reservoir monitoring (PRM) system on the Johan Sverdrup field, one of the five biggest oil fields on the Norwegian continental shelf.

With 380 kilometers of seismic cables installed on the seabed and more than 6500 acoustic sensors covering an area of more than 120 square kilometers, Johan Sverdrup will deploy ASN's seismic technology and will be one of the largest fiber optic seismic systems of its kind.

For the first time on any field on the Norwegian continental shelf (NCS), the seismic technology will be in place ready to optimize production in time for start-up. The seismic cables will be installed on the seabed of Johan Sverdrup during 2019.

With PRM, seismic sensors are permanently embedded into the seabed which enables more frequent and much improved seismic images of changes in the reservoir. The system on Johan Sverdrup will be based on ASN's optical fiber technology which is designed to allow very high performance and superior reliability.

Johan Sverdrup will be developed in different phases: Phase 1 is expected to start up in late 2019 with production capacity estimated at 440,000 barrels of oil per day and Phase 2 is expected to start up in 2022, with full field production estimated at 660,000 barrels of oil per day. Peak production on Johan Sverdrup will be equivalent to 25% of all Norwegian petroleum production. With a recovery ambition of 70%, Johan Sverdrup will become one of the fields in the world with the highest recovery factor. Statistics from the Norwegian Petroleum Directorate shows that average recovery from the NCS is at 46%.

Philippe Piron, president of Alcatel Submarine Networks, said: "This new PRM contract further strengthens the relationship between ASN and Statoil, as well as it demonstrates the relevance of PRM technology to provide 4D seismic data to the most technology advanced oil Companies. Our fiber optic reservoir monitoring system will support Statoil in increasing oil recovery in a cost-efficient way."
