H018 Time-Lapse Multiple Removal Technique to Improve 4D Interpretation in the Gas Cloud Region at Valhall P.J. Hatchell* (Shell International Exploration & Production BV) & P.B. Wills (Shell International Exploration & Production BV) SUMMARY Since late 2003 more than six seismic surveys have been acquired for the Valhall Life-of-Field-Seismic (LOFS) project an OBC system installed to provide frequent and high-resolution snapshots of the field production.

An examination of the seismic data near the reservoir zone shows
