The borehole response of four-electrode (induced polarization) IP logging tools has been modeled by analytic and potential-field methods with separate inductive coupling correction. A prototype IP logging tool has been developed and tested in both fresh water and saline brines. The tool has been demonstrated to measure the cation exchange capacity of shaly sands and provide superior lithology discrimination. A focused version of the tool has been proposed and modeled.
