Three Stage Approach

A three stage approach as described above has been adopted to develop the Company. Each stage is defined by a number of activities to reach particular goals and objectives. To date, the Company has drilled five deep wells. Habanero 3, Australia's first commercial scale geothermal well was completed 5 February 2008 to a depth of 4,200 metres.

Stage 1 is the Development of an underground heat exchanger. It involves drilling the first deep well and the development of a subterranean, engineered, heat exchanger in hot granites with a temperature of >250oC. This will be followed by the drilling of a production well and proving the output of the underground heat exchanger through circulation.  This "Proof of Concept" was completed in early 2009. 

Stage 2 is the Development of a Commercial demonstration EGS geothermal power plant and includes:

  • Field development plan;
  • Design of a Commercial Demonstration Plant (CDP);
  • Drilling of 9 wells (5 production, 4 injection);
  • Construction of the CDP; and
  • Completion of transmission infrastructure.

The Company is currently working towards making a financial investment decision on a 25 MW CDP during 2013.

Stage 3 is the Commercial Scale Power Plant.  It is anticipated that the optimal power station design will be multiple 50 MW modules given the unique position faced by Geodynamics in The Cooper Basin.

Stage 3 will involve the roll out of ten 50 MW plants. The achievement of Stage 3 will represent the first full scale commercial exploitation of the geothermal resources in The Cooper Basin.
