Opportunities for conventional and unconventional discoveries in Australia’s Northern Territory Dorothy Close, Director Regional Geoscience, NT Geological Survey
Australia’s Northern Territory • Australia’s fastest growing economy • Growing resources sector • Ideally located for Asian markets • Pro-development government
Australia’s Northern Territory • North-south infrastructure corridor including gas pipeline, rail and road • Modern port and LNG processing facilities in Darwin • Vast, prospective underexplored area – numerous frontier onshore basins with new discoveries being made • High unconventional gas and oil potential
Major developing LNG hub • Existing Darwin LNG facility (Conoco-Phillips) from BayuUndan field – capacity for expansion • A$34 billion Ichthys LNG project under construction in Darwin (Inpex) • 883 km pipeline from Ichthys field to Darwin Darwin LNG Inpex LNG
Increased tenure uptake • Rapidly expanding exploration in onshore basins • Rapid increase in tenure coverage in previous 4 years to >90% of onshore area • Opportunities for farm-in and joint venture arrangements with junior to mid-tier companies • NT moving to a competitive process for future acreage release
Major petroleum investors • Santos Ltd / Magellan Petroleum (NT) Pty Ltd • Oil and Gas production – Palm Valley / Mereenie • Pangaea Resources • Seismic – McArthur Basin/Beetaloo Sub-basin • Falcon Oil and Gas Australia Pty Ltd • Exploration well & seismic – Beetaloo Sub-basin • Statoil - PetroFrontier Pty Ltd • Exploration well & seismic – Georgina Basin • Santos Ltd - Central Petroleum Limited • Exploration well & seismic – Amadeus Basin • Armour Energy Pty Ltd • Exploration wells and seismic – McArthur Basin • Santos Ltd – Tamboran Resources Limited • Seismic – McArthur Basin • Beach Energy Ltd – Territory Oil and Gas Geophysics and exploration wells – Bonaparte Basin
Prospective onshore basins • McArthur Basin (incl. Beetaloo Sub-basin) • Palaeo-Mesoproterozoic • undeveloped gas and oil basin • 180,000 km2 outcropping, ≤ 350,000 km2 subsurface extent • multiple proven petroleum systems and prospective shales • Wiso Basin • Neoprot – Palaeozoic • Unexplored correlative of Georgina Basin • Georgina Basin • Neoprot – Palaeozoic • High unconventional oil and gas potential from Cambrian shales
Prospective onshore basins • Bonaparte Basin • Palaeozoic – Mesozoic • Onshore extension of major producing basin offshore in Timor Sea • Pedirka-Eromanga Basin • Mesozoic stacked basins • Includes correlatives of Cooper Basin in SA/Qld • Amadeus Basin • Neoprot- Palaeozoic • gas and oil production • multiple petroleum systems • frontier opportunities away from producing fields
Onshore exploration 2012/13 McArthur Basin • Batten Fault Zone: Armour Energy • 3 wells in 2012, 2 wells in 2013 • flows equivalent to 3.3 million standard cubic feet of gas per day from Glyde-1 well (2012) • Live oil in shales in Lamont Pass-3 well (2013) • Beetaloo Sub-basin (east) : Santos • 500 line km of 2D seismic in 2013 • Beetaloo Sub-basin: Falcon Oil and Gas • 3490 line km of 2D seismic in 2012/13 under previous farm-in with Hess • Beetaloo Sub-basin (west) : Pangaea Resources • Previously unexplored area • 1400 line km of 2D seismic in 2013
Onshore exploration 2012/13 Amadeus and Georgina basins • Georgina Basin: Petrofrontier-Statoil • 3 horizontal wells drilled in 2012 • positive oil shows but hampered by technical issues • seismic acquired in 2013 • five vertical wells planned in 2014 • Surprise: Central Petroleum • western Amadeus Basin • exploration well flowed 200-400 barrels per day of light sweet crude • first major onshore oil discovery in NT for 50 years • planning production in 2014 • Amadeus Basin: Santos-Central Petroleum • 1587 km of regional 2D seismic • exploration well in progress targeting Neoproterozoic petroleum system Surprise
Targeted new geoscience • Increased resolution of regional gravity data in producing and frontier basins • Complete aeromagnetic and radiometric coverage • Unconventional hydrocarbon assessment across major basins • Targeted studies within the Amadeus and McArthur basins including: • Stratigraphic revision and regional correlations • Basin architecture studies and construction of 3D models
McArthur Basin new geoscience • Interpreted subsurface extents of prospective McArthur Basin and Beetaloo Sub-basin stratigraphy • Interpretation of basin architecture using upgraded geophysical datasets • Generation of 3D model • Unconventional assessment of multiple prospective stratigraphic intervals • Hyperspectral scanning of all retained drillcore • Ongoing regional scale gravity acquisition
Australia’s Northern Territory • Major emerging onshore petroleum industry • Outstanding opportunities for conventional and unconventional targets in multiple frontier basins • Located close to Asia with existing LNG hub • High quality new geoscience to support petroleum exploration
