Effectiveness of the Reciprocity Principle for Dipole-dipole Electrical Resistivity Survey in Field

The reciprocity principle of source and receiver array holds in dipole-dipole electrical resistivity survey. To examine the aspects of source voltage and current and of the potential difference of reception electrodes for heterogeneous medium, a vertically contacted half space model involving high and low-resistivity medium is defined, and the numerical simulation is carried out in the case of dipole-dipole electrode array configuration. And to examine the effectiveness of the electrode optimization based on the reciprocity principle in actual field situations, the numerical experiments for the model involving high and low resistivity with random noise are performed and analyzed.
