Slide 4: Why Paralana? Evidence for Thermal Anomalism
Why Paralana? For personal use only Evidence for Thermal Anomalism › Hot Springs › Fossil Hydrothermal Breccias › Elevated groundwater temperatures › High heat flow (Mt Gee 126 mWm-2) › Poontana basin insulator
Slide 5: Exploring for Heat – Paralana Project
Exploring for Heat – Paralana Project For personal use only 62uWm-3 22uWm-3 Insulator Up to 20 times normal granite: average = 8 times Permian Mt Painter Basement Adelaidean Curnamona Mt Painter Basement Basement Normal basement Early modelling indicated 200oC at approximately 3.6 - 4 km
Slide 6: Poontana Basin
Poontana Basin For personal use only 109oC › Heat flow of 129 mWm-2 › Modeled 200oc at ~ 3.6 – 4 km (Seismic Line 84 SPG)
Slide 7: Development Model – Heat Exchanger Within Insulator
Development Model – Heat Exchanger Within Insulator For personal use only › Higher Permeability › Chemically Stable › Lower Frac Challenge? › Adelaidean – bedding / joint surfaces = Cheaper Power!
Slide 8: Paralana Project – Commercial Overview
Paralana Project – Commercial Overview For personal use only › Commercially viable at all stages. Small off grid market (5-30MWe) (Heathgate) followed by large on grid development (260 MWe+) › Expenditure well leveraged for proof of concept, then potentially fully funded to initial commercial demons
