Use of PP and PS Time-Lapse Stacks for Fluid-Pressure Discrimination

A-23 USE OF PP AND PS TIME-LAPSE STACKS FOR FLUID-PRESSURE DISCRIMINATION Abstract 1 A complementary method to achieve quantitative information about reservoir property changes during production is to measure shift in two-way traveltime within a given reservoir section. A practical example of how this method can be used to give additional information about pressure and saturation changes in reservoir segment is given in Landrø 2001 Landrø 2002 and Landrø et al. 2003. In this paper we investigate how combined use of time-lapse PP and PS seismic data can be processed and analyzed for the discrimination between pressure and saturation changes.
