Oil exploration wells (2000-13), western Cooper – Eromanga o 56% located with 3D were
discoveries (and find-size )o 30% located with 2D were
discoverieso Average 2.53 mmbo find sizeo 10 operators for 22 companies

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
Conclusions for the Cooper-Eromanga Basins
1. >50% success rate in finding average 2.5 mmbo post 3D
2. Huge shale, tight sandstone and deep coal gas plays.
3. Proven 1,000+ metre gas columns can be developed with a mix of (mostly) verticals and (fewer) horizontal wells
4. 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
5. Exploration and appraisal ramping up with several E&Ps and gas customers now funding exploration. Expect deals
