Abstract：Time-lapse seismic interprets the difference between base data and monitored data as reservoir change. We have conducted a pre-stack matching inversion on time-lapse seismic data in the Oilfield A, West Africa, a typical deep water fan sand reservoir. The matching inversion based on rock physics obtains water flooding sensitivity cube and elastic attribute cube. By fluid replacement on rock physics analysis, reservoir rock physics parameters are ranked for their fluid sensitivity in water flooding to determine object attributes of the matching inversion. Time-lapse seismic matching inversion is based on the pre-stack seismic inversion. The discussion focuses on wavelet, constraint model, and key parameters of matching inversion. The flooding sensitivity attribute cube and its differences help remaining oil prediction for further oil development.
