Water tank testing of time domain IP profile with multi-current transmission method based on CDMA technique


Abstract
We confirmed that time domain chargeability measurement with multi-current transmission method based on CDMA technique is reliable through water tank experiment. As the method to improve the efficiency of ERT measurement, the method to inject current at plural electrodes simultaneously was developed. In our past work, we proposed to apply this method to time domain IP profile. In this paper, we conducted water tank experiment using mineral ore with certain IP effect in the purpose of verifying our method to calculate chargeability from the data acquired by multi-current transmission measurement.
