Geothermal Exploration

Our geophysical surveys help reveal what’s happening beneath the surface in a non-invasive way. Zonge provides imaging techniques to identify hot fluids, clays, brines, sinters, and geologic structures that are key to finding and developing geothermal resources. By combining them, we give you a reliable picture of the subsurface, helping reduce risk and guide smarter decisions from the start.

Geothermal Project Experience

Newberry Volcano, Oregon

Zonge International conducted gravity surveys at Newberry Volcano in 2007 and 2010 for Davenport Newberry, followed by a magnetotelluric (MT) survey in 2011. The combined interpretation drew on more than 100 MT stations from the 2006 and 2011 surveys, together with gravity data and drill-hole lithology, to refine the subsurface model and evaluate the area’s hydrothermal potential.

Steptoe Valley, Nevada

As part of a Sandia National Laboratories-led geothermal research project, Zonge International conducted a combined 40-station MT and CSEM survey and processed the resulting data in northern Steptoe Valley, Nevada. The public overview presents the broader investigation and its findings: Geophysical Imaging at Steptoe Valley, Nevada.
