  3. 3. IntroductionResource and Energy Symposium – 22 May 2012 Slide 3
  4. 4. South Australia & Broken Hill – A strong resources link• Broken Hill was an early and important part of South Australia’s resources and energy sector• South Australia is in the midst of a resurgence in exploration activity, driven by: – The Lead-Zinc initiatives of the late 1980’s – The ‘Business Plan’/ aeromag flown over SA and financed by the state government – And further initiatives since, resulting in…..• Major capital investment programs, such as: Photo courtesy of DMITRE – Olympic Dam – Prominent Hill The unsung heroes of the resources and – Cooper Basin conventional and energy industries are the trailblazing unconventional drilling programs pioneers Resource and Energy Symposium – 22 May 2012 Slide 4
  5. 5. A new mining boom with critical energy needs • SA now at a critical energy point: – Alinta to shut down Playford brown coal power station – The distortionary effects of too much wind power What are the alternatives? • ‘Greener’ fuels such as wind, solar and geothermal are expensive and not as ‘green’ as many think • There is an increasing reliance on imports for diesel and jet fuel ……and growing demand for explosives and fertilisers ~ 40% increase to 2025Dwindling coal supply and demandwith ‘greener’ fuel challenges make GAS the future energy source Source: Core Energy Group 2011 Resource and Energy Symposium – 22 May 2012 Slide 5
  6. 6. The benefits of natural gas • High hydrogen, hence cleaner burning than coal • Reduced water demand • Able to provide flexibility to cover base and peak loads • Potential to underpin the development of a new and scalable petrochemical industry (explosives, fertilisers etc) • Possibility of building a new era for high purity diesel and jet fuel via gas to liquids • ….but, Eastern Australia is short gas Uncontracted demandSignificant increase in demand for gas expected from 2015 due to LNG export and east coast demand Source: Core Energy Group 2011 Resource and Energy Symposium – 22 May 2012 Slide 6
  7. 7. Can Australia replicate the North American shale boom?Resource and Energy Symposium – 22 May 2012 Slide 7
  8. 8. EIA – United States Gas Production Projection 2000 2012 US Natural Gas Production 1990-2020 US Natural Gas Production 1990-2035Sources: History: Advanced Resources International, Inc. (ARI). Projections: Source: US Energy Information Administration, AEO2012 Energy Information Administration, AEO2000, DOE/EIA-0383 (2000) Early Release Overview, 23 January 2012 (Washington, DC, December 1999), reference case In 2000, EIA projected EIA is now projecting shale conventional gas production would and tight gas will represent 70% dominate future supply of US supply by 2035 Resource and Energy Symposium – 22 May 2012 Slide 8
  9. 9. Gas options for Eastern Australia – a critical time Australian East Coast 2P Reserves* Non-LNG ~ 9k PJ East Coast 2P Reserves held by LNG proponents ~ 40k PJ * Adapted from Energy Quest, February 2012 ~ 80% of East Coast 2P reserves are owned by parties developing LNG projects or with LNG aspirations Resource and Energy Symposium – 22 May 2012 Slide 9
  10. 10. The Shale Gas Option – but what to look for? • In 2007 Beach, understanding the success of US shale gas developments, reviewed Australian basins for opportunities • Beach identified technical key contributors to success – Shale thickness – Organic content – Mineralogy – Maturity – Over-pressure – Ability to take high equity position – Proximity to infrastructure/market access Resource and Energy Symposium – 22 May 2012 Slide 10
  11. 11. The Shale Gas Option – key technical attributes Parameters for gas in place Parameters for deliverability • Shale thickness • Overpressure (drive) • Lateral continuity • Mineralogy (brittleness) • Organic content • Maturity (hydrocarbons) • Maturity Cross- Drainage Bulk Permeability sectional areaGas in place area density GIP = A * h * ρ * GCt Q = k * A * ΔP Pressure Gradient μ Volumetric Reservoir Total gas flow rate thickness content Viscosity of flowing fluid Resource and Energy Symposium – 22 May 2012 Slide 11
  12. 12. Primary focus: Cooper Basin - Nappamerri Trough• Primary focus was to find the best shale acreage in Australia• All regions in Australia were considered• Key factors considered in identifying the primary target: – Rock quality, i.e. organic content, brittleness – The right environment, i.e. thick, overpressured, thermally mature – Ability to take high equity position – Proximity to infrastructure/market The Nappamerri Trough Permian section access under-explored off-structure Resource and Energy Symposium – 22 May 2012 Slide 12
  13. 13. Nappamerri Trough- geological setting• The deepest and largest of the northeast-southwest trending troughs in the Cooper Basin• Thick Permian section of coals, siltstones, sandstones and shales• Roseneath Shale, Epsilon Formation and Murteree Shale (REM) were the initial focus for shale gas Shale gas target Basin centred gas target Resource and Energy Symposium – 22 May 2012 Slide 13
  14. 14. Over-pressure • Over-pressure created by hydrocarbon generation • The pressure gradient in the Nappamerri Trough is ~0.72 psi/ft • Over-pressure necessary for gas drive • Preservation of pore throats during compaction enhancing permeability Pressure (psi) 0 2000 4000 6000 8000 10000 0 1000 Depth (m) 2000 Top Overpressure 3000 REM Depths ΔP ~3,000psi 4000 Resource and Energy Symposium – 22 May 2012 Slide 14
  15. 15. Maturity for deliverability• With increasing maturity expect enhanced dewatering and dehydration of clays• Loss of capillary water enhancing permeability• Fluid viscosity is a function of maturity• Methane is less viscous than wet gas and all things being equal, methane will flow better• High level of maturity enables abundant gas generation creating over-pressure Source: Tucker.M, Sedimentary Petrology, 1998 Resource and Energy Symposium – 22 May 2012 Slide 15
  16. 16. Fluid viscosity is important for higher flow rates • Dry gas will flow better than gas with high liquids content in thick homogeneous shales • If liquids are present, interbedded (mixed) lithologies (e.g., sandstones) are better • Beach’s focus for liquids-rich plays are in basins with these potential attributes (e.g., Bakken – North Dakota, Otway Basin (SA and Victoria) and Bonaparte (NT)) Resource and Energy Symposium – 22 May 2012 Slide 16

  19. 19. Shale and beyond - program highlights to date• Results from Encounter-1 and Holdfast-1 exceeded expectations due to: – Gas saturated target zone potentially over one kilometre – ~2 MMscfd initial flow rate from Holdfast-1 – Booking 2 Tcf contingent resource – 480 metres of core recovered assisting technical analysis – Gas flows up to 750,000 scfd from one frac stage in the Patchawarra from Encounter-1• Moonta-1 vertical well completed with mud logs indicating gas saturation throughout Permian section• Streaky-1 vertical exploration well has spudded300+ Tcf of gas in place estimated for PEL 218 Resource and Energy Symposium – 22 May 2012 Slide 19

  25. 25. Sovereign risk now a real issue for Australia• Need to remove uncertainties and disincentives, i.e. the carbon tax and PRRT• First five years are critical for a nascent industry• Technical advances through Beach’s unconventional program will aid ‘Greener’ power, such as geothermal• Unconventional gas and oil has the ability to power mining production, supply the domestic power market and LNG export market• Enhanced gas production is critical for explosives manufacture and fertiliser production Downstream producers should be pushing government for removal of upstream tax impediments to free up gas production Resource and Energy Symposium – 22 May 2012 Slide 25
