Application of the United Nations Framework Classification for Resources (UNFC) to Geothermal Energy Resources

Selected Case Studies

image of Application of the United Nations Framework Classification for Resources (UNFC) to Geothermal Energy Resources

This publication includes a set of 14 case studies on the application of the United Nations Framework Classification for Resources (UNFC) to geothermal energy from Australia, Germany, Hungary, Iceland, Italy, the Netherlands, New Zealand, the Philippines and Russian Federation. The case studies presented here illustrate the application of the geothermal energy specifications for the uniform use of UNFC in different contexts. These application examples from different countries provide a range of scenarios in the classification of geothermal resources in a manner consistent with the classification of other energy resources.

Habanero

Habanero is an Enhanced Geothermal System (EGS) resource located in hot granite near the town of Innamincka in northeast South Australia. The Potential Geothermal Energy Source was first identified by a petroleum exploration well which encountered hot granite at a depth of 3,748 m. Analysis of regional gravity data showed that the granite batholith extends over approximately 1,000 km2. Geodynamics Limited acquired geothermal exploration licences covering 991 km2 of the gravity anomaly and these have subsequently been converted into geothermal retention licences. The company has drilled four full-sized geothermal wells into the granite at Habanero, 10 km south of Innamincka. Two further full-sized exploration wells have also been drilled into the granite at Jolokia, 10 km west of Habanero, and at Savina, 10 km southwest of Jolokia. All six of these deep wells have shown signs of having encountered pre-existing faults within the granite.
