Dr. Zoë Vestrum has a diverse academic background in geophysics, with thesis topics in seismic, geodynamics, and electromagnetics. Her doctoral research focused on creating robust resistivity models by integrating resistivity information from different electric and electromagnetic methods into magnetotelluric (MT) inversion. This integration is important because MT cannot properly resolve near-surface features. Specifically, near-surface conductors, such as clay deposits, create a large-amplitude response in the MT data that is difficult to model. By incorporating near-surface resistivity information from time-domain airborne electromagnetics, direct current resistivity, or well-log information, the MT inversion can model the deeper resistivity structure more reliably.

Part of this research involved incorporating large volumes of well-log data into regional resistivity models of Alberta. She brings this holistic, multiphysics approach to Axiom Exploration Group as we acquire a wide range of geophysical data.
