Statoil, WesterGeco Establish Long-Term Reservoir Monitoring

WesternGeco has signed an agreement with Statoil ASA for the industry's first long-term seismic reservoir monitoring program. Through this agreement, WesternGeco becomes Statoil's preferred contractor for time-lapse seismic surveys over the Norne and Heidrun fields in the Norwegian Sea for five- and six-year periods, respectively.

Future monitor surveys using Q-Technology(a) on the Halten and Donna Terrasse will follow the successful Q-on-Q surveys over the Norne field in 2001, 2003 and 2004, and the Heidrun field in 2001 and 2004.

For these surveys, all Q-Marine(a) seismic acquisition parameters will be identical to the previous surveys, giving the best possible time-lapse (4D) survey results to detect fluid movement for reservoir management and production. Q-Marine active streamer steering allows accurate positioning of streamers for reliable repeat surveys.

"This long-term commitment by Statoil to our Q-Technology is a break-through agreement for our industry," said Roar Bekker, manager, WesternGeco Europe. "This agreement will enable both organizations to better plan for the surveys, which are crucial to Statoil's ongoing production of these fields."

Q is the WesternGeco proprietary suite of advanced seismic technologies for enhanced reservoir location, description and management.
