Well measurements and seismic attributes can be used to derive multi-dimensional calibration functions that are applied to seismic attributes to map reservoir properties. Estimation of various properties is guided by multiple seismic attributes simultaneously. The estimates fit the well measurements and are guided by seismic data away from the wells. Significance estimation and error mapping provide a quantitative measure of confidence. Specific seismic attributes have been found to correlate well with individual reservoir properties, thus improving the ability to map them. For example, interval velocity and acoustic impedance often correlate well with porosity. This mapping process was used to define effective porosity and water saturation along the reservoir.
