3D geological modelling of potential geothermal energy reservoirs in the Flinders Ranges, Australia

Abstract

The Flinders Ranges in Australia are located within the well defined South Australian Heat Flow Anomaly. Anomalously high heat flow is recorded in this area, offering world-class opportunities for the development of significant and economically viable Enhanced Geothermal Systems (EGS). Here, we show how a combination of potential field data interpretation and modelling with surface and sub-surface geological constraints in addition to finite element thermal models, enable us to to best delineate potential geothermal reserves. This study could be used as a benchmark for any EGS exploration in the world.
