Well Resistivity Imaging Technique
Core rule: Place positive electrode A in the hole and negative electrode B on the surface or in other holes.
The measuring electrode is located near the power supply electrodes A and B and between A and B.
According to the performance of electrical instruments, multiple groups of M and N combinations can be designed to observe multi-channel data and improve acquisition efficiency.
