    CGGVeritas goes back to work on Ekofisk

    Projects and Operations // June 14, 2012

    CGGVeritas will shortly begin acquiring a fourth repeat survey (LoFS04) on the Ekofisk field in the North Sea as part of the multi-year Life-of-Field Seismic (LoFS) programme for which it was awarded both the seismic data acquisition and processing.

    Mobilization was due this month; the shooting period will last approximately one month in accordance with the LoFS programme schedule.

    The programme is being acquired with a four-component (4C) fiber-optic permanent reservoir monitoring (PRM) solution, deploying 16,000 Sercel OPTOWAVE ocean-bottom channels.

    More than two years after the full-scale fiber-optic installation all channel sensors are providing data that is being utilized to provide 4D reservoir monitoring images to the client.
     
    Quality Control and processing of the data from each repeat survey is performed by a team of CGGVeritas acquisition and processing specialists based in the client’s dedicated processing center in Tananger (Norway).

    In addition to the full optical sensor network trenched at the seafloor, a fiber-optic connection to the shore allows real-time remote operation.

    CGGVeritas imaging experts are drawing on their experience and expertise in processing multicomponent 4D data to generate high-resolution time-lapse seismic images of the reservoir.
