P061 Monitoring Effective Stress Changes in Fault Zones from Time-Lapse Seismic Reflection Data – A Model Study J.R. van der Neut* (Delft University of Technology) M.K. Sen (University of Texas Institute for Geophysics) & K. Wapenaar (Delft University of Technology) SUMMARY A fault can be interpreted as a non-welded interface causing a discontinuity of displacement in a reflecting wave field that can be described with a linear slip boundary condition. We represent a fault as a layer of cracks; its thickness being small compared to the seismic wavelength. An increase of effective stress can be induced by a drop of
