A system and method for producing a conductivity log, unaffected by shoulder effect and dip, from voltage data developed by a well tool (205) disposed in a borehole. The method involves accessing the voltage data developed by the tool, processing the data, reconstructing two-coil voltage data, and computing differences of the two-coil data, to derive a conductivity profile representative of the formation. A system including a well tool adapted to move through a borehole with an apparatus (210) coupled to the tool. The apparatus adapted with means to access voltage data developed by the receivers disposed on the well tool. Th e apparatus further adapted with means for boosting the voltage data, means for reconstructing t wo- coil voltages from the boosted voltage data, means for processing the reconstructed two-co il voltage data, and means for producing a conductivity log from the processed two-coil voltages.
