Resistivity Imaging Using Flexible Electrode Combination Data Collected with a Multi-Channel, Full Waveform System

In this paper we suggest a major break from the usual practice of resistivity imaging using standard electrode arrays, such as Schlumberger, Wenner or dipole-dipole. Rather, one should take as many measurements as practical from a fixed set of electrodes and record from numerous combinations of current and potential electrodes. With this intention, a new prototype multi-channel and multi-electrode, full waveform resistivity acquisition system which permits such recording strategy has been developed. It allows for significant data collection capacity and flexibility and is therefore suitable for 2D or 3D surface or cross-hole resistivity tomography and for general electric monitoring.
