50 Years State of the Art in IP and Complex Resistivity

It is worth looking back to see how far the field of geophysics exploration has come. Presented in 2003, this paper was a combination of retrospective and forecast in which Ken Zonge outlined industry progress after a renewed interest in the IP method in the early 1950s. He then summarized Zonge company progress over the […]
