Statoil has awarded a contract to Alcatel Submarine Networks for Permanent reservoir monitoring (PRM) on the Johan Sverdrup field. The seismic technology – a potential digital enabler for the field – will be a key contributor to delivering on Johan Sverdrup’s 70% recovery ambition.
With 380 kilometers of fiber optic seismic cables installed on the seabed and more than 6500 acoustic sensors covering an area of more than 120 square kilometers, Johan Sverdrup will have 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 use optical fiber technology which allows for continuous recording of changes in the subsurface.
The frame agreement with Alcatel Submarine Networks also includes opportunities for future collaboration around technology development and solutions to further maximize the potential from the PRM system.
