A hydrocarbon exploration method is disclosed for generating anisotropic resistivity models of a subsurface reservoir from seismic and well data using a rock physics model. In one embodiment, the method comprises: selecting wells within a region of interest (); obtaining a plurality of rock properties () and adjusting selected rock parameters () in the calibration of the rock physics model at the well locations; inverting porosity and shale content from seismic data (); propagating the calibrated rock physics model to the region of interest () and calculating effective resistivity for the entire region of interest (). The inventive method also provides for analyzing the uncertainty associated with the prediction of the resistivity volume.
