Introduction
Slide 4 Resource and Energy Symposium – 22 May 2012
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:
– Olympic Dam
– Prominent Hill
– Cooper Basin conventional and unconventional drilling programs
The unsung heroes of the resources and energy industries are the trailblazing
pioneers

Slide 5 Resource and Energy Symposium – 22 May 2012
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
Dwindling coal supply and demand with ‘greener’ fuel challenges make
GAS the future energy source

~ 40% increase to 2025
Slide 6 Resource and Energy Symposium – 22 May 2012
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
Significant increase in demand for gas expected from 2015 due to
LNG export and east coast demand Source: Core Energy Group 2011
Uncontracted demand
Slide 7 Resource and Energy Symposium – 22 May 2012
Can Australia replicate the North American shale boom?
Slide 8 Resource and Energy Symposium – 22 May 2012
EIA – United States Gas Production Projection
In 2000, EIA projected conventional gas production would
dominate future supply
EIA is now projecting shale and tight gas will represent 70%
of US supply by 2035

Slide 9 Resource and Energy Symposium – 22 May 2012
Gas options for Eastern Australia – a critical time
~ 80% of East Coast 2P reserves are owned by parties developing LNG projects or with LNG aspirations
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
Slide 10 Resource and Energy Symposium – 22 May 2012
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
Slide 11 Resource and Energy Symposium – 22 May 2012
The Shale Gas Option – key technical attributes
Parameters for gas in place
• Shale thickness
• Lateral continuity
•Organic content
•Maturity
Parameters for deliverability
•Overpressure (drive)
•Mineralogy (brittleness)
•Maturity (hydrocarbons)

Slide 12 Resource and Energy Symposium – 22 May 2012
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 access
The Nappamerri Trough Permian section under-explored off-structure
Slide 13 Resource and Energy Symposium – 22 May 2012
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

Slide 14 Resource and Energy Symposium – 22 May 2012
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

Slide 15 Resource and Energy Symposium – 22 May 2012
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
Slide 16 Resource and Energy Symposium – 22 May 2012
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))

Slide 19 Resource and Energy Symposium – 22 May 2012
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 spudded
300+ Tcf of gas in place estimated for PEL 218

Slide 21 Resource and Energy Symposium – 22 May 2012
• Good working relationship with pastoral owners and other stakeholders
• Co-operative not competitive land use
• Semi-desert country
• Relatively flat topography
• Well established oil and gas infrastructure
• Raw and sales gas pipelines cross PEL 218 and ATP 855P
• Multiple commercialisation options

Slide 23 Resource and Energy Symposium – 22 May 2012
Summary
• Decisive and aggressive exploration
• Confirmed shale gas and basin centred gas objectives
• Unique shales
• Substantial multi-level resource play
• Fast paced and comprehensive forward exploration program
Slide 24 Resource and Energy Symposium – 22 May 2012
An opportunity for Australia
Slide 25 Resource and Energy Symposium – 22 May 2012
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
