It is demonstrated that time-lapse seismic signatures can be directly calibrated with history data from producing and injecting wells. When this procedure is applied to a field over which two or more repeated surveys have been shot at different calendar times, the correlation coefficients that relate the seismic differences to the reservoir's pressure and saturation variations can be determined. By utilizing several seismic attributes that respond differently to reservoir change, a separation into independent estimates of pressure and saturation can be achieved. This technique is applied to field data from the UKCS with favorable results.
