This Oil and Gas Resources of Australia 2010 publication is the successor to Oil and Gas Resources of Australia 2009 and continues as the definitive reference on exploration, development and production of Australia's petroleum resources. The tables describe: - wells drilled - seismic surveys - petroleum discoveries - petroleum reserves - production and development, including forecasts of crude oil and condensate and a listing of offshore facilities

Australia has significant gas resources capable of meeting the needs of domestic and international consumers for decades. Commercial viability of the resource depends on a number of factors such as geology, infrastructure, resource quality, and water depth. Further exploration is required to bring on Australia's lowest cost gas resources.

Bores sunk at Cremorne in 1891 struck coal at approximately 2802 feet. A company was formed to work the coal, but was refused permission to operate at Cremorne. A site at Balmain was secured, and the Birthday Shaft was sunk to a depth of 2,937 feet between 1897 and 1902. This report provides an overview of the occurrence of natural gas and workings for the period 1897 to 1948. Gas yields, commercial production, leakage problems, and the use of testing to determine the behaviour of gas in the mine are the key subjects that are addressed in this report.

This report is a summary of information collected between November, 1948 and July, 1949 in the course of visits to the United Kingdom and the United States. The main subjects investigated were the complete gasification of coal, particularly in respect of its application to Victorian brown coal, the production of oil by synthesis and the production and refining of shale oil. Information was sought on a considerable number of other interests in the field of fuel technology as the opportunity offered. The authorities consulted were invariably experts in their respective fields, and great care was taken to record their information accurately. The report is a summary of recent developments and not an exhaustive study of the subjects mentioned. A considerable mass of detail has been excluded but is available on record for further reference.

This point dataset contains offshore Oil and Gas Platforms located in Australian waters that include infrastructure facilities for the extraction, processing and/or storage of oil and natural gas.

The Clarence-Moreton and the Surat basins in Queensland and northern New South Wales contain the coal-bearing sedimentary sequences of the Jurassic Walloon Coal Measures, composed of up to approximately 600 m of mudstone, siltstone, sandstone and coal. In recent years, the intensification of exploration for coal seam gas (CSG) resources within both basins has led to concerns that the depressurisation associated with future resource development may cause adverse impacts on water resources in adjacent aquifers. In order to identify the most suitable tracers to study groundwater recharge and flow patterns within the Walloon Coal Measures and their degree of connectivity with over- or underlying formations, samples were collected from the Walloon Coal Measures and adjacent aquifers in the northern Clarence-Moreton Basin and eastern Surat Basin, and analysed for a wide range of hydrochemical and isotopic parameters. Parameters that were analysed include major ion chemistry, -13C-DIC, -18O, 87Sr/86Sr, Rare Earth Elements (REE), 14C, -2H and -13C of CH4 as well as concentrations of dissolved gases (including methane). Dissolved methane concentrations range from below the reporting limit (10 µg/L) to approximately 50 mg/L in groundwaters of the Walloon Coal Measures. However, the high degree of spatial variability of methane concentrations highlights the general complexity of recharge and groundwater flow processes, especially in the Laidley Sub-Basin of the Clarence-Moreton Basin, where numerous volcanic cones penetrate the Walloon Coal Measures and may form pathways for preferential recharge to the Walloon Coal Measures. Interestingly, dissolved methane was also measured in other sedimentary bedrock units and in alluvial aquifers in areas where no previous CSG exploration or development has occurred, highlighting the natural presence of methane in different aquifers. Radiocarbon ages of Walloon Coal Measure groundwaters are also highly variable, ranging from approximately 2000 yrs BP to >40000 yrs BP. While groundwaters sampled in close proximity to the east and west of the Great Dividing Range are mostly young, suggesting that recharge to the Walloon Coal Measures through the basalts of the Great Dividing Range occurs here, there are otherwise no clearly discernable spatial patterns and no strong correlations with depth or distance along inferred flow paths in the Clarence-Moreton Basin. In contrast to this strong spatial variability of methane concentrations and groundwater ages, REE and 87Sr/86Sr isotope ratios of Walloon Coal Measures groundwaters appear to be very uniform and clearly distinct from groundwaters contained in other bedrock units. This difference is attributed to the different source material of the Walloon Coal Measures (mostly basalts in comparison to other bedrock units which are mostly composed of mineralogical more variable Paleozoic basement rocks of the New England Orogen). This study suggests that REE and 87Sr/86Sr ratios may be a suitable tracer to study hydraulic connectivity of the Walloon Coal Measures with over- or underlying aquifers. In addition, this study also highlights the need to conduct detailed water chemistry and isotope baseline studies prior to the development of coal seam gas resources in order to differentiate between natural background values of methane and potential impacts of coal seam gas development.

This report is a partial update of the national assessment series of Australia's energy resources, which was first released in 2010. This interim release provides an overview of Australia's identified and potential fossil energy resources: oil, gas, coal, uranium and thorium. It focuses on resource quantities. A full updated version of AERA will be released in December 2016. It will add hydro, solar, wind, geothermal, bioenergy and ocean energy in conjunction with the Australian Renewable Energy Agency, along with energy resource market information from the Office of Chief Economist. AERA provides the crucial information and data for comparing energy commodities and reviewing resources available in Australia and the world. In turn, this information can be used while considering resources and energy policies.

A major concern for regulators and the public with geologically storage of gas is the potential for the migration of gas (e.g. CO2) via a leaky fault or well into potable groundwater supplies. Given sufficient CO2, an immediate effect on groundwater would be a decrease in pH which could lead to accelerated weathering, an increase in alkalinity and the release of major and minor ions. Laboratory and core studies have demonstrated that on contact with CO2 heavy metals can be released under low pH and high CO2 conditions (particularly Pd, Ni and Cr). There is also a concern that trace organic contaminants could be mobilised due to the high solubility of many organics in supercritical CO2. These scenarios could potentially occur under a high CO2 leakage event but a small leak might be barely perceptible yet could provide an important early warning for a subsequent and more substantial impact. Different approaches are required for the detection and quantification of these low level leaks and are the subject of this paper. A 3 year groundwater survey was recently completed in the Surat Basin, which forms part of the Triassic-Cretaceous, Great Artesian Basin (GAB) aquifer sequence. In addition to a comprehensive water and isotopic analysis of samples from groundwater wells, gases were collected from groundwater samples and analysed for composition, '13CCO2, '13CCH4 and '2HCH4. Methane is prevalent in the major aquifers in the Surat Basin (e.g. Mooga, Gubbermunda and Hutton sandstones) and is invariably associated with a bacterial (methanogenic) carbonate reduction source, evident from its isotopic signature ('13CCH4 ~ -70', '2HCH4 ~ 220'). In addition to methane and low levels of CO2, trace levels of ethane are often detected.
