A Saturation Law for Quantitative 4D Seismic Analysis of a Turbidite Reservoir Undergoing Waterflood

P075 A Saturation Law for Quantitative 4D Seismic Analysis of a Turbidite Reservoir Undergoing Waterflood C. MacBeth* (Heriot-Watt Institute of Petroleum Engineering) & K.D. Stephen (Heriot-Watt Institute of Petroleum Engineering) SUMMARY Reservoir management can be very much improved by increasing our knowledge of fluid changes within the field. Time-lapse seismic can offer this information provided an accurate relationship between the fluid-bulk modulus estimated from seismic and the true reservoir saturation condition is known. This relationship is generally simplified by ignoring the interaction of fluid heterogeneity and seismic at various scales thus significantly increasing errors and uncertainty in saturation estimates.
