A method for surface estimation of reservoir properties, wherein location of and average earth resistivities above, below, and horizontally adjacent to the reservoir (3) are first determined using data in the vicinity of the reservoir (3). Then dimensions and probing frequency for an electromagnetic source (4,5) are determined to maximize transmitted vertical and horizontal electric currents at the reservoir (3). Next, the source (4,5) is activated approximately centered above the reservoir (3) and a plurality of components of electromagnetic response is measured with a receiver array (10). Geometrical and electrical parameter constraints are determined using the data. Finally, the electromagnetic response is processed using the geometrical and electrical constraints to produce inverted vertical and horizontal resistivity depth images.
