Abstract
Summary
Resistivity and time domain IP measurements using a 100% duty cycle square waveform current injection signal, and measuring the IP responses during current transmission, was modelled numerically and tested in the field against a traditional IP current injection with a 50% duty cycle waveform and measuring during the current off-time. The results show that the approach is practically applicable and can reduce the measuring time substantially as well as increase the signal-to-noise ratio by measuring the IP-response during the current on-time.
