At HDR, we provide clients with the geologic analysis and resource characterizations that underpin financing.  We advise governments in ascertaining their geothermal resources. We help you take your tenement holding forward to a viable producing resource. Our laboratory, modelling, mapping and analysis lead to the temperature and flow estimates necessary to predict power.

We work in months, not years.  Below are images and videos of our modelling work.
