Time Domain IP Profile by Multi-current Transmission Technique - Water Tank Experiment and SP Noise Effect Estimation

We conducted time domain chargeability measurement by multi-current transmission technique using a water tank and mineral ore which has certain IP effect in the purpose of verifying the method to calculate chargeability from the data acquired by multi-current transmission measurement using Code Division Multiple Access (CDMA) technique . We also evaluate the effect to chargeability calculation of SP noise thorough numerical experiment. We confirmed that time domain chargeability measurement is available through the experiment using water tank and mineral ore. We also evaluated the effect of SP noise to time-domain chargeability measurement by numerical experiment. The precise current control and appropriate SP management are important for reliable chargeability measurement with multi-current transmission measurement.
