Abstract
It is well known that differential pressure change will induce time‐lapse seismic attribute changes by acting on both the rock matrix and the pore fluids. It would be very helpful for seismic amplitude interpretation if we can separate the time lapse seismic attribute changes induced by rock matrix and pore fluids respectively. Based on petrophysical data and laboratory rock physics data from a North Sea gas reservoir, this study showed that the overall time‐lapse seismic responses can be approximated by the arithmetical sum of time‐lapse seismic property change induced by dry rock matrix and by pore fluids respectively. Identify and separation of the differential pressure effects could bring a new insight regarding discrimination between pore pressure and saturation changes.
