Abstract

Summary

We present a field trial testing the use of stacked radio waves for the purpose of generating a qualitative proxy for geothermal potential. This study was completed over 27 sites near abandoned onshore oil and gas wells across the United Kingdom. The data was collected between 2017 and 2018 in three different fieldtrips. Each site was scanned by transmitting non-invasive pulses of electromagnetic energy of low power (under 5 milliwatts) and frequencies ranging from 1MegaHertz to 70MegaHertzs. This developing technology hinges on the transmission of pulses of electromagnetic waves at the speed of light into the subsurface from a transmitter while simultaneously recording reflected pulses with an adjacent receiver. The output from the processed data was validated against geothermal and heat flow models for the United Kingdom. This method of identifying energy gamma troughs as temperature anomalies is good for targeting hot zones, due to the high contrast in temperature with adjacent units.

A widespread application of a survey using this technology could yield great benefits in confirming and further delineating confidence in geothermal potential, and the use of a remote sensing, low environmental impact technique would be in sync with the goals at the centre of the energy transition.
