Slide 5: Why Paralana?
Why Paralana? Evidence for Thermal Anomalism › Hot Springs › Fossil Hydrothermal Breccias › Elevated groundwater temperatures › High heat flow (Mt Gee 126 mWm-2) › Poontana basin insulator
Slide 6: Exploring for Heat – Paralana Project Insulator
Exploring for Heat – Paralana Project 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 7: Poontana Basin
Poontana Basin 109oC › Heat flow of 129 mWm-2 › Modeled 200oc at ~ 3.6 – 4 km (Seismic Line 84 SPG)
Slide 8: Development Model – Heat Exchanger Within Insulator
Development Model – Heat Exchanger Within Insulator › Higher Permeability › Chemically Stable › Lower Frac Challenge? › Adelaidean – bedding / joint surfaces = Cheaper Power!
Slide 9: Paralana Project – Commercial Overview
Paralana Project – Commercial Overview › 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 demonstration scale 30MW pla

Recording Period April 08 – June 09
Slide 12: Pre-stimulation Seismic Events
Pre-stimulation Seismic Events Recording Period April 2008 – June 2009 Array detecting small events
Slide 13: Paralana 2 – Drilling
Paralana 2 – Drilling New Weatherford Owned 2000HP Le Tourneau Lightning Rig 57 metres high ~ 10 Stories Arrived at Port Pirie 11 May 09 85 Semi-Trailer Loads Spudded June 30, 2009
Slide 14: Paralana 2 – Operations
Paralana 2 - Operations › Petratherm/Beach – extensive stakeholder and community consultation – Adnyamathanha Community, Beverley Uranium Mine , Epic Pipe line, Arkaroola Village › Beach Petroleum – Manager of Drilling Operations › HSE - to date no lost time injuries › Only minor shake down issues ›
Slide 15: Scenario Planning vs. Murphy's Law
Scenario Planning vs. Murphy’s Law
Slide 16: Paralana 2 – Drilling: Very Hard Rock Formations
Paralana 2 – Drilling Very Hard Rock Formations – slow ROP 1-3 m/hr Tested several BHA arrangements to optimise ROP Remember this is a Wildcat Well !
Slide 17: Paralana 2 – Drilling Completed to 4012 m
Paralana 2 - Drilling Completed to 4012 M – 9 Nov 2009 › First well designed following low-risk, standard operating methods › Steady but slow drilling due to hard formations › Wireline logging underway › Will be fully cased and cemented › Inflow zones encountered from 3690m
Slide 18: Paralana 2 – Geothermal Brines
Paralana 2 – geothermal brines › Inflow zones from 3690m › Brine samples taken › Wireline Logging Program – Reservoir Characterisation! › Temperature › Permeability › Insitu stress field › Geology › Rock Properties
Slide 19: Current Planned Future Work Program
Current Planned Future Work Program › November 2009: Wireline Logging › 1st Qtr 2010: Mini frac program/fracture stimulation design › 2nd Qtr 2010: Multizone fracture stimulation › 3rd Qtr 2010: drilling of the Paralana 3 deep producer well › End 2010: Circulation Test – Proof of Concept › Early 201
