  3. NORTHERN TERRITORY • The grant of petroleum titles has begun to flow. • - 5 new title grants in the last year. • - 23 license applications over the last 4 years. • NT basins will be featured at the Central Australian Basins Symposium (CABS) in Alice Springs, August.

  4. ONSHORE PETROLEUM EXPLORATION PERMITS

  5. Amadeus Basin • > 100 untested anticlinal structures • Established oil and gas systems • New seismic interpretations highlight fractured gas reservoir potential in the southeast. • Subsalt and other salt related plays to be featured at CABS.

  6. Suggested Amadeus Application Areas

  7. Georgina Basin • Previously harmed by negative geological dogma. New studies show the basin has been unroofed, hence oil mature source rocks and reservoirs occur at shallow depths. • Two prolific Middle Cambrian oil systems. • Seismic indicates sandstones developed in high energy channel, delta and turbidite facies. Exploration fairway is 300-400 km across. • Oil pools could range up to 100s mmbbl at depths of 300-900 m.

  9. Annual value of production ~A$10 billionPerth = centre of Australia’s oil industryCanning & Perth Basin acreage bids close 27 October 2005 WESTERN AUSTRALIA

  10. Canning Basin • Oil and gas shows • Mature source rocks • Regional seal • Favourable reservoir development • Large mapped structures • LO5-1 5,999 km2 (1.48 million acres) • LO5-2 5,092 km2 (1.25 million acres)

  11. Canning Basin • Fairways and leads mapped • Ordovician, Devonian and Permian plays • Economics modelled • Data and reports now available

  12. Perth Basin • Interest revitalised by Jingemia, Cliff Head and ongoing oil discoveries • Blocks are <10km from gas fields & discoveries • Parmelia gas pipeline connects to Perth • Sealed highway connects to Kwinana oil refinery • Permian, Jurassic plays • LO5-3 444 km2 (109,714 acres) • LO5-4 810 km2 (200,155 acres)

  15. Cooper Basin oil success rates

  16. Cooper Basin CO 2004-A closes 28 July Potential Jurassic oil play, Permian tight gas play 1600 km2 (395,370 acres) Upcoming acreage Partial acreage relinquishments due 2006+ Conjunctive land access agreement (ILUA) planned Consolidated vacant acreage to be released in one round. MOOMBA

  17. Otway Basin No current onshore releases. Upcoming PEL expiries and relinquishments to be consolidated into a large block. SA coastal strip now available plus 2 offshore blocks.

  21. 31 exploration titles over all major basins • Large under-explored basins cover 500,000 km2 • Extensive coal seam methane targets • Palaeozoic and Mesozoic sequences with producing analogues in Qld & SA • Data packages now available

  22. New legislative regime - Petroleum and Gas (Production and Safety) Act 2004. • Exploration tenure now only granted as a result of a call for tenders. • Tenders likely to be called in the second half of 2005. • Seeking expressions of interest in areas to be released in the call for tenders.
