Integrating Core Measurements and Borehole Logs With Seismic Data in the Statfjord 4D Project

A-18 INTEGRATING CORE MEASUREMENTS AND BOREHOLE LOGS WITH SEISMIC DATA IN THE STATFJORD 4D PROJECT ANNE-KARI FURRE and IVAR BREVIK Statoil R&D Postuttak 7005Trondheim Norway Abstract The Statfjord field straddles the border between Norway and UK. A total of 570 Sm 3 of oil has been produced from the field since production start in 1979. As part of an increasing oil ratio (IOR) scheme a seismic reservoir monitoring study was carried out based on totally three seismic surveys; one in 1979 (pre-production) one in 1991/92 and one in 1997. The seismic surveys together with a large amount of well logs
