In order to test tomographic inversion schemes under controlled conditions, we have developed a forward electromagnetic model, using the volume current method (VCM). The algorithm can handle thin irregular-shaped bedding planes as well as inclusions or localized anomalies. It is thus ideal for modeling oil trap regions in the earth. Both transmission and reflection images, in magnitude and phase, are presented. Model results are given for a complex lithology as appropriate for an enhanced oil recovery zone. Particular emphasis is placed upon understanding the qualitative effects of bedding layer planes, both continuous and broken, on the electromagnetic response of an elliptical shaped anomaly. The point is made that resolution of reservoir features in complex lithologies, as encountered in enhanced oil recovery applications, requires accurate processing of both amplitude and phase tomographic data.
