Abstract

Summary

An extension of previously developed methods to calculate in-situ 3D temperature directly from 3D geology models in {I}3D GeoModeller {/I}software now allows for quantification of the uncertainty associated with those calculations. This work is being collaboratively undertaken by Intrepid Geophysics and Geoscience Australia, and will offer Australia’s geothermal industry both: i) a new predictive tool helping to reduce the risk of Enhanced Geothermal System (EGS) exploration and heat resource estimation, and ii) stochastic temperature and heat flow maps of Australia.
