Resistivity And Induced-Polarization Probing in the Vicinity of a Spherical Anomaly

The mathematical formulae governing the interaction of a low-frequency source of electric current with a spherical anomaly are given. These formulae are used to determine the apparent resistivity and induced-polarization response between electrodes located within boreholes in the medium. Numerical results are given illustrating the spatial variation of these parameters.
