"Hot dry rock (HDR) geothermal energy is obtained by circulating water between injection and production wells\r\nthrough hot subsurface rocks. The recovered hot water should be around 250ºC for efficient electricity generation. South\r\nAustralia has become a focus for HDR developments due to its exceptionally hot subsurface rocks. Geothermal\r\nExploration Licences have been issued in South Australia following modifications to petroleum legislation. New South\r\nWales has issued geothermal licences after modifications to mining legislation. Renewable Energy Certificates, mandated\r\nby the Commonwealth Government, increase the competitiveness of electricity generated from renewable sources such\r\nas geothermal energy.\r\nPrevious HDR projects have focussed on areas of known high geothermal gradient, based, for example, on experience\r\nfrom petroleum wells such as the European Soultz-sous-Forêts site and Geodynamics’ Habanero-1 well in the Cooper\r\nBasin. An alternative strategy is to explore for the highest geothermal gradients closest to electricity markets.\r\nMNGI/Petratherm holds Geothermal Exploration Licences within the exceptionally hot South Australian Heat Flow\r\nAnomaly and will target buried thermally anomalous granites and radiogenic iron oxides therein. Simple thermal\r\ncalculations indicate that under suitable circumstances temperatures of 250ºC may be attained at depths <4 km within the\r\nlicences. The thermal conductivity of the cover rocks is as important a factor as the heat-generating potential of the\r\nbasement. There exists a continuum of geothermal energy sources from hot, shallow, high-permeability aquifers to\r\ndeeper, tighter aquifers, to hot fractured basement, to basement hot dry rocks. Indeed end-member HDR-type targets may\r\nbe relatively rare and commercial HDR exploration may also target conventional geothermal resources."^^ . "2004-09" . .
