Australia has a thriving oil and gas industry with expanding infrastructure and many exploration opportunities. Geologically the country contains potential for large oil and gas discoveries with extensive sedimentary basins. Australia is also one of the world leaders in providing low cost geological data with an open Acreage Release process and competitive taxation regimes. Politically Australia is very stable with a very high standard of living and a long-standing democratic culture based on the rights of the individual and the rule of the law. There is a free market philosophy which welcomes foreign investment - Australia has no mandatory local equity requirements and has no government owned oil companies. Government facilitation of investment includes fast-tracking of approvals processes for major projects. This CD provides some basic Australia data including: Oil and Gas Resources of Australia 2003 This publication is the definitive reference on exploration, development and production of Australia's petroleum resources. It covers exploration, reserves, undiscovered resources, development, coalbed methane resources, production, crude oil and shale oil and supporting information and statistics. It includes a forecast of Australia's crude oil and condensate production up to the year 2020, and sustainability indicators for petroleum resources. Information on Australia's petroleum data availability is also included. An estimate of Australia's undiscovered oil and gas potential and a review of geological sequestration of carbon dioxide in Australia is included. Australian Research and Promotional Material Australian research includes research papers for Australia, Australia regions (Northwest Shelf and the Southern Margin) and CO2 Sequestration.

This data set contains information on Oil and Gas pipeline infrastructure. This dataset has been converted from Microstation format used in a map "Petroleum Exploration and Development Titles" published annually in APRIL. Attributes have been added to comply with data standards and minor coding of line work has been achieved using annotation from the map. Further data has been added, specifically for the specific Acreage Release Areas.

The natural gases are composed of a limited number of individual compounds, mainly of C1-C5 hydrocarbons and non-hydrocarbon compounds (CO2, N2, noble gases etc.). Their compositions and isotopes of single compounds provide critical information to decipher the origin and evolution of natural gases. Efficient analysis of these compounds is paramount for timely application of this important dataset.

The article provides an annula update on Australia's energy scenarion, focussing on offshore oil and gas exploration and production and advertsing the current open acreage release round.

ORIGIN AND USE OF HELIUM IN AUSTRALIAN NATURAL GASES C. Boreham1, D. Edwards1. R. Poreda2, P. Henson1. 1 Geoscience Australia, Canberra, Australia; 2 University of Rochester, NY, USA Over 800 natural gases representative of Australia's hydrocarbon-producing sedimentary basins have been analyzed for their helium (He) content and around 150 gases for their helium isotopic composition, supplemented by isotopic compositions of the higher noble gases. Australian natural gases have helium abundances to over 10%, with the highest values in the Amadeus Basin, in central Australia, while 3He/4He ratios range from around 0.01 to 4.2 Ra (Figure 1). The onshore Gunnedah Basin of southeastern Australia and the offshore Bass and onshore/offshore Otway basins in southern Australia show the highest 3He/4He ratios, indicating a significant mantle contribution. Interestingly, the offshore Gippsland Basin, adjacent to the Bass Basin, has slightly lower 3He/4He ratios. In the Gunnedah Basin, the associated CO2 has a relatively low abundance compared to extreme concentrations of CO2 in some Otway Basin wells, which are associated with recent volcanism. The onshore Bowen and Cooper basins of eastern Australia, where natural gases are predominately sourced from Permian coals, show intermediate 3He/4He ratios with the former having a higher mantle contribution. At the other end of the spectrum, low 3He/4He ratios characterize natural gases of the offshore North West Shelf (Bonaparte, Browse, Carnarvon) and onshore/offshore Perth basins in northwestern and southwestern Australia, respectively, and radiogenic helium predominates. Hence the sometimes extensive volcanic activity and igneous intrusions in these western basins is not expressed in the helium isotopes. The accompanying high CO2 contents (up to 44%) of some of these North West Shelf gases, together with the carbon isotopic composition of CO2, infer an inorganic source most likely from the thermal decomposition of carbonates. The geochemical data suggest that the origin of helium in Australian natural gas accumulations is region specific and complex with the component gases originating from multiple sources. The relative low CO2/3He ratio for many natural gases indicates a systematic loss of CO2 from most basins. The process by which CO2 has been lost from the system is most likely associated with precipitation of carbonates (Prinzhofer, 2013). The age of the source (and/or reservoir) rock has a primary control on the helium content with radiogenic 4He input increasing with residence time (Figure 1). References: Prinzhofer, A., 2013.

Using numerous illustrations this comprehensive black and white resource describes the formation, trapping and uses of natural gas as a non-renewable energy source. The exploration and recovery methods of gas are described, as are Australia's natural gas potential and environmental issues such as greenhouse gases. This 110 page booklet includes student activities with suggested answers. Suitable for secondary Years 9-12.

February 2001 Bonaparte Basin - Gas Data The gas database contains molecular compositional and isotopic data for gases from the Bonaparte Basin as exported from AGSO's Orgchem database on 6th February 2001. The output represents those gases for which the data is considered not to be "commercial-in-confidence". Also included is a document which gives a description of the data fields.
