We have investigated induced polarization (IP) effects in hydrocarbon‐bearing artificial rocks at frequencies greater than 100 Hz. We have examined the instrumental and electrode phase responses of Zonge International's complex resistivity (CR) system, and optimized the performance of the Zonge system for IP measurements over the 1 mHz to 10 kHz frequency range.

The reliability of the high‐frequency IP measurements were confirmed by independent measurement of the same samples using the Novocontrol BDS 80 system. Our results confirm the presence of IP effects in hydrocarbon‐bearing rocks, and suggest the necessity to account for IP effects in the interpretations of electromagnetic data, particularly in induction logging data.
