Abstract This paper researches the sphere beside a well when performed in ground-well IP, forwarding the underground semi-space electric field with analytical solution, and inversing its depth and distance to well by the secondary field abnormal potential differences. We validate the correctness of these forward and inversion formulas by computer simulation, analyze their physical principle, and give their applicable conditions. This research has a definite significance for quantitative analysis of probing the underground objectives with IP.
