Abstract

Summary

“Time-lapse seismic surveys have proven extremely valuable to guide reservoir management decisions. Changes in seismic reflection amplitudes can provide information on fluid contact movements or pressure changes, whereas variations in travel-times of seismic signals can provide information on geomechanical effects such as reservoir compaction, overburden strain and subsidence. Here, we present a new methodology to obtain reservoir strain changes via geomechanical inversion of seismic time-lapse time-strains. If a linear pressure-strain relationship is assumed, the volumetric strains can be translated into reservoir pressure changes. We demonstrate the method on an example from the Danish North Sea and discuss some observations.”
