A-10 QUANTITATIVE ESTIMATION OF COMPACTION AND VELOCITY CHANGES USING 4D IMPEDANCE AND TRAVEL TIME CHANGES Abstract 1 J. STAMMEIJER 1 and M. LANDRØ 2 1 Shell Expro 1 Altens Farm Road Aberdeen AB12 3FY UK 2 Dep. Of Petroleum Engineering and Appl. Geophysics NTNU For some hydrocarbon reservoirs severe compaction of the reservoir rocks is observed. This compaction is caused by the production and is often associated with changes also for the overburden. Time-lapse seismic data can be used to monitor this compaction process. Since the compaction causes both changes in layer thickness as well as changes in the seismic
