is designed to measure the apparent resistivity with simultaneous forced probe configuration switching over (lateral sonde-normal sonde) and to measure rock spontaneous potential.
The measurements are performed via environmental excitation by alternating electric field (electrodes A, B) and potential drop measurement (at M, N electrodes). The spontaneous potential is measured when the external electric field is turned off.
KSP-43 Electrical logging tool is to be run with one-core and triple-core logging.
