    MASSY, France – Equinor has contracted CGG’s Geoscience division Subsurface Imaging to process seismic data from the Johan Sverdrup permanent reservoir monitoring (PRM) system in the Norwegian North Sea.

    A CGG team based in Equinor’s offices in Stavanger will work with the client on delivering time-lapse 4D images to the Johan Sverdrup asset group within days of acquisition.

    By analyzing ‘snapshots’ of the reservoir during production, Equinor geoscientists expect to optimize production management and hydrocarbon recovery.

    The 31-month contract carries an option for two three-year extensions.

    CGG claims to have processed the majority of the full-scale PRM projects conducted by the industry to date, including at Equinor’s Snorre and Grane fields in the North Sea since 2013 and 2014, respectively.

    With PRM, seismic sensors are permanently embedded into the seabed which enables more frequent and 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.
