P076 4D Seismic Pore Pressure Inversion – The Effect of Production Induced Overburden Changes P.V. Angelov* (TU-Delft) R. Arts (TU-Delft; TNO-Utrecht) & K. Wapenaar (TU-Delft) SUMMARY The quantification of production or injection induced changes in reservoir properties (i.e. pressure and saturation) can be determined using seismic attributes derived from 4D seismic such as travel time shifts and amplitude changes. In this type of studies frequently the assumption is made that changes only occur in the reservoir and not in the overburden. Especially in the case of gas production or gas injection (storage) associated with large pressure change in the reservoir
