Abstract

Summary

Direct Hydrocarbon indicators from electromagnetic measurements have always been questionable. In K. Vozoff’s work they translate to resistive layer and understanding the reliability of resolving resistive layers. Vozoff worked on this subject extensively with the team around him in the 1980s and 1990s.

The work started with feasibility studies and a field demonstration over a small oil field in Western Australia. A detailed starting model was derived from the seismic and well logs and joint inversion of electric and magnetic field yield inferred porosity or percentage sandstone section. Vozoff not only pioneered methodologies in electromagnetics but also details of inversion methods that are still of great interest today.

Without mistake, he anticipated failure or success of the individual task on hand.
