  2. Oil exploration wells (2000-13), western Cooper – Eromanga • 56% located with 3D were discoveries (and find-size ) • 30% located with 2D were discoveries • Average 2.53 mmbo find size • 10 operators for 22 companies Retention Leases for Oil Proven Cooper-Eromanga oil play Petroleum Licence Holders

  3. Cooper Basin Composite • and Deep Coal Plays Gas saturated composite play

  4. Cooper Basin, South Australia • Patchawarra Fm. Pressure Gradient Composite Play below ~2,900m Base Patchawarra depth structure map showing unconventional gas wells

  5. Supply-chain goal posts: 2,800 wells @ 3Pj / well over 15 yrs to attain 8,422 Pj (~10% of 93 TCF EIA estimate for gas from shales) • Work for government-industry: • Discover competence possibly without capacity to supply rigs, pipe, roads, rail, materials, services, people, etc, etc. • Foster pre-qualification for tenders; and • Enable clusters and IPOs for budding multi-nationals

  6. Conclusions forthe Cooper-Eromanga Basins • >50% success rate in finding average 2.5 mmbo post 3D • Huge shale, tight sandstone and deep coal gas plays. • Proven 1,000+ metre gas columns can be developed with a mix of (mostly) verticals and (fewer) horizontal wells • Initial unconventional resource estimates for the Cooper Basin are high: • EIA potential sales gas from shales: 93 TCF • Rough estimate of sales gas in Composite Play: ~ 300 TCF • Exploration and appraisal ramping up with several E&Ps and gas customers now funding exploration. Expect deals
