Improvement of 4D Seismic Interpretations by Integration of Well Information; Examples from the Gullfaks Field Northern North Sea

A-3 IMPROVEMENT OF 4D SEISMIC INTERPRETATIONS BY INTEGRATION OF WELL INFORMATION; EXAMPLES FROM THE GULLFAKS FIELD NORTHERN NORTH SEA 1 OSCAR KELDER PER DIGRANES and LARS-KRISTIAN STRØNEN Statoil 4035 Stavanger Norway Abstract The last few years time lapse seismic has proven to be a powerful reservoir management tool for the Gullfaks oil field in the North Sea. It considerably improves the drainage understanding of the field and has resulted in several potential new infill drilling targets of which one already has successfully been drilled. The validity of several 4D observations is often hampered by interpretational uncertainties due to data quality
