Abstract

Discrete element method (DEM) is used as a tool for modeling seismic wave propagation as well as stresses and strains associated with reservoir depletion. The advantage of DEM lies in its ability to model strain localization and evolution of fractures, which can be directly linked to time-lapse seismics and micro-seismic events. For this purpose, DEM is tested to verify its ability to model wave propagation. Then a simplified 2D synthetic model for typical North Sea field is constructed. The simulated geomechanical response to reservoir depletion is compared to that obtained by use of the Finite element method. Finally a simple 4D seismic profile is created for the reservoir top.
