For personal use only Dr Chris Giles, Technical Director 8 December 2009
Slide 3: Geothermal Resources – Key Assets
Geothermal Resources – Key Assets For personal use only • Projects based on sound geological concepts. • Frome Project – Hot Fractured Rock (HFR) model. 5,000 km2 similar in prospectivity to the Cooper Basin. • Robe‐Penola Project (formerly Crower project)– Hot Sedimentary aquifer (HSA) model. 3,500
Slide 4: Proximity to Transmission Lines is Key
Proximity to Transmission Lines is Key For personal use only Frome is 60 kms from the Broken Hill connection access at Honeymoon Mine Crower is close to the National Grid and the Portland Aluminium Smelter
Slide 5: Hot Fractured Rock Model
Frome Project - Hot Fractured Rock Model For personal use only •HFR Model – aims to exploit >200oC pressurised water within fractured granite or volcanic bedrock. •Highly radiogenic (heat generating) granite outcrops to the south around Mt Victoria. •Granite “heat engine” plunges gently to the north
Slide 6: 2009 Achievements
Frome Project – 2009 Achievements For personal use only 1. Drilled two 1800m wells 2. Published inferred geothermal resource 3. Completed seismic survey 4. Planned ‘proof of concept’ wells
Slide 7: 2009 Achievements: Deep wells drilled
Frome Project – 2009 Achievements For personal use only 1. Drilled 2 deep wells (26 km apart): * Frome 12 ‐ 1761 metres ‐ 93.5 oC * Frome 13 ‐ 1809 metres ‐ 96 oC * Granite proven * Granite fractured
Slide 8: 2009 Achievements: Inferred geothermal resource
Frome Project – 2009 Achievements For personal use only 2. Published inferred geothermal resource • High geothermal gradient confirmed • Gradient > 40 oC per km over > 500 km2 area • Inferred geothermal resource estimate of 84,000 PJ (thermal) [ASX 13th July 2009]
Slide 9: Temperature Gradient
Frome 12 Temperature Gradient For personal use only Frome 12 temperature gradient similar to Frome 3 93.5 0C at 1761 metres depth
Slide 10: 2009 Achievements: Seismic survey completed
Frome Project – 2009 Achievements For personal use only 3. Seismic survey completed • East west line 27 km long • Passed near existing well Frome 12, and the planned ‘proof of concept’ wells Frome 15 and 16 • Granite position validated
Slide 11: Geological cross-section
Frome Project – 2009 Achievements For personal use only Geological cross‐section
Slide 12: 2009 Achievements: Proof of concept wells
Frome Project – 2009 Achievements For personal use only 4. ‘Proof of concept’ wells sited, planned and cost estimated Significant advantages: • TVD 3250m • Temperature of 155 oC • All oil drilling tools and techniques appropriate • Ensign Rig # 30: proven sling shot • Granite: fractured not over pre
Slide 13: Next Steps
Frome Project – Next Steps For personal use only • Drill two wells (Frome 15&16) into fractured granite (3,000‐ 3250m). • Hydrofracture to enhance permeability and test flow between wells. • Large investment ‐ budgeted cost for all of above is $17 million. • Specialist expertise required fr drilling
Slide 14: Penola-Robe Project - Current Status
Penola-Robe Project - Current Status For personal use only • 7 GELs covering more than 3,500 km2 along northern margin of Otway Basin. • Highest geothermal gradients in entire Otway Basin from well temperature measurements. • Pretty Hill Formation aquifer volume in Robe and Penola troughs (total 886
Slide 15: Penola-Robe Project – Hot Sedimentary Aquifer Model
Penola-Robe Project – Hot Sedimentary Aquifer Model For personal use only • Exploit 125‐150oC water within naturally permeable sediments. • Balance between permeability (decreases with depth) and temperature (increases with depth). • Hot basement highs may locally elevate geothermal gradients. • Pow
Slide 16: Penola-Robe Project – Geological Setting
Penola-Robe Project – Geological Setting For personal use only • Northern margin of Otway Basin onlaps older granitic basement. • Features deep, narrow troughs (Penola and Robe troughs) and adjacent bedrock highs. • Moderately well understood geology supported by extensive seismic data from petroleu
Slide 17: Oblique View of Potential Aquifer
Oblique View of Potential Aquifer For personal use only
Slide 18: Penola-Robe Project: Seismic Surveys
Penola - Robe Project: Seismic Surveys For personal use only >1000 km of seismic surveys are being enhanced & reinterpreted
Slide 19: Objectives for 2010
OBJECTIVES FOR 2010 For personal use only FROME PROJECT • Drill injection & production wells for flow test. • Secure a major partner and investigate best commercialisation alternatives. CROWER PROJECT • Refine HSA targets via detailed seismic interpretation. • Learn from other explorers drilling nea
