Geothermal Energy Predictive Modelling

Kenex has recently developed a predictive model targeting hot rock style geothermal resources in the Northern Territory. These types of geothermal systems have become increasing sought after as increasing power consumption, rising fuel costs and concern about greenhouse gas emissions impact on more traditional energy sources.


Hot rock style geothermal systems have the additional benefit of being the only renewable energy source capable of meeting base load electricity requirements. Geothermal exploration is set to increase in the Northern Territory as the as the Northern Territory geothermal permitting system comes on line.


The Northern Territory contains several moderate to high heat producing granite suites and is mostly positioned within the Central Australian Heat Flow Province, a belt of anomalously high surface heat flow. It is believed to contain several regions capable of generating hot rock style geothermal energy. At present, the territory relies on three independent gas powered electricity grids, Darwin-Katherine, Tennant Creek and Alice Springs, and a large number of smaller diesel fired and solar power stations that supply remote communities and industry. Power generation at many of these stations could be supplemented or replaced by hot rock type geothermal energy, particularly in situations where the geothermal prospect is located nearby.


Prospectivity analysis using the Fuzzy Logic approach was used to integrate the various predictive themes relevant to hot rock style geothermal systems. A significant number of exploration targets have been generated, and six of these are located within 150 km of a significant population centre or industrial power consumer.
