Permeability Inversion and Water-Cut Forecasting Using Saturation History from Time-Lapse Seismic and Seismic Attribute Maps

A-16 PERMEABILITY INVERSION AND WATER-CUT FORECASTING USING SATURATION HISTORY FROM TIME-LAPSE SEISMIC AND SEISMIC ATTRIBUTE MAPS Abstract 1 Time lapse seismic is used to monitor the reservoir during production. Assuming seismic repeatability it is possible to couple seismic changes in the reservoir to flow property changes as a result of production. Successive slices give direct information over the speed at which the saturation front propagates through the a-priori unknown permeability field. The propagation speed of the saturation front contains useful information about the fluid flow velocity field in the observed medium. A relation between the velocity map and desired reservoir
