Geoscience Australia:• applies geoscience to Australia’s most important challenges• is the Government’s technical advisor on all aspects of geoscience• is custodian of the geoscience data and information for the nation
Geoscience Australia’s Petroleum ProgramRole: Attract exploration investment to Australia by building a prospectus of energy resource potential
Strategies:
• Provide information to support the annual offshore acreage release
• Provide a functional national repository of offshore petroleum data and samples
• National Offshore Petroleum Data and Core Repository
• National Offshore Petroleum Information Management System (NOPIMS)
• Identify new prospective energy provinces through the acquisition, analysis and delivery of pre‐competitive information
• Provide independent information and advice to government and other stakeholders

Geoscience Australia’s Role: Precompetitive Data
GA's Regional Petroleum Program - June 2015
Relationship between exploration and precompetitive information

Stratigraphic Frameworks
Australia’s offshore frontier basins
Inventory of Offshore Frontier Basins
GA's Regional Petroleum Program - June 2015
• Comprehensive assessment of:
• Geology
• Petroleum systems
• Exploration status
• Data coverage
• 35 offshore basins and sub‐basins
• Analysis of the critical exploration and geoscientific questions
• Recommendations for future work Download from:www.ga.gov.au
• Onshore inventory now underway
Stratigraphic Frameworks
GA's Regional Petroleum Program - June 2015
• Regularly updated regional basin biozonation charts
• Data packs available – Timescale Creator software
• Available for 12 basins
Download from: www.ga.gov.au
Regional Integration Studies:NW and W Margin Regional Structural Study
GA's Regional Petroleum Program - June 2015
2014-2015 FY
• New Browse Basin aeromagnetic data
2015 onwards
• Regional structural & stratigraphic mapping
• Depth to basement; volcanic distribution; margin segmentation
• Characterise basement as a guide to rheology and thermal history
Download from: www.geoscience.gov.au
• Tectonic evolution, structural architecture, re‐activation
• Trap integrity and fault‐risk
• Distribution and impact of magmatic rock
Browse Aeromagnetic Survey
Regional Integration Studies:Australian Source Rocks
Collaborative studies to identify and characterise hydrocarbon sources, families and systems both onshore and offshore
GA's Regional Petroleum Program - June 2015
2014‐2015
• Browse petroleum accumulations and source rock study
2015‐2017
• NW shelf: expand existing work into Triassic and older
• Larapintine petroleum systems: source rock evaluation in Paleozoic basins of northern Australia
• Cooper, Georgina Basin pilot studies
Cooper Basin Source Rock Atlas
Geographic Frontiers
• Improve knowledge of the resource potential of the Australian Marine Jurisdiction
• Provide an environmental baseline
• Inboard areas: e.g. Northern Houtman
• Remote areas: e.g. Lord Howe Rise
Lord Howe Rise (GowerMooreMonawai)
Southern Sorell,South Tasman Rise
N. HoutmanS. Carnarvon
GA's Regional Petroleum Program - June 2015
Acquisition of new data in poorly understood and remote frontier basins
Geographic Frontiers: Houtman Seismic Survey
GA's Regional Petroleum Program - June 2015
• Northern Houtman and Zeewyck Sub‐basins: large, potentially prospective frontier depocentres
• Immediately adjacent to prospective areas of the northern Perth Basin
2014‐2015
• Nov‐Dec 2014 ‐ 3308 line km of 2D seismic data acquired
M/V Duke
2015‐2016
• Data processing/ interpretation
2016 onwards
• Assess petroleum prospectivity and suitability for acreage release
Geographic Frontiers: IODP – Lord Howe Rise
• One of the largest remaining geological frontiers
• Sparse scientific knowledge ‐ No deep drill sites
GA's Regional Petroleum Program - June 2015
2015‐2016: Full proposal submission
2016‐2017: Pre‐site surveys in conjunction with JAMSTEC
2017‐2018: Stratigraphic Drilling (Total Depth: 2.5–3.5 km)
Chikyu
• Purpose: recover a complete Early to Late Cretaceous stratigraphic record from a rift depocentre and sample the pre‐rift sedimentary succession
Recent CO2 Storage Potential Studies
• Improve understanding of Australia’s sedimentary basins and their potential for greenhouse gas storage
• Pre‐competitive datasets relevant to petroleum exploration
• Gippsland Basin Seismic surveys
• GDPI10 2D survey (2010)
• 2D Infill survey (2015)
• Marine sampling surveys
• Browse Basin (2014)
• Vlaming Sub‐basin (2012)
• Bonaparte Basin (2011)
• Gippsland Basin (2014)
