Abstract: Time-lapse seismic feasibility studies for compactible reservoirs such as Ekofisk in the North Sea require coupled flow simulation and geomechanical deformation modeling. We present an algorithm for staggered-in-time, 2-way coupling of flow and geomechanics and indicate what impact the coupled code has on calculation of seismic properties. Modifications to the geomechanics code allow changes in pore pressure to be included in the total stress calculation. The geomechanics code produces volumetric strain-induced porosity and permeability updates for the flow simulator. We validate our loosely-coupled simulator against a fully-coupled flow and mechanics simulator from ARCO.
