This petroleum systems summary report provides a compilation of the current understanding of petroleum systems for the South Nicholson Basin and Isa Superbasin region. The contents of this report are also available via the Geoscience Australia Portal at https://portal.ga.gov.au/, called The Petroleum Systems Summary Assessment Tool (Edwards et al., 2020). Three summaries have been developed as part of the Exploring for the Future (EFTF) program (Czarnota et al., 2020); the McArthur Basin, the Canning Basin, and a combined summary of the South Nicholson Basin and Isa Superbasin region. The petroleum systems summary reports aim to facilitate exploration by summarizing key datasets related to conventional and unconventional hydrocarbon exploration, enabling a quick, high-level assessment the hydrocarbon prospectivity of the region.

Following the publication of Geoscience Australia record 2014/09: Petroleum geology inventory of Australia's offshore frontier basins by Totterdell et. al, (2014), the onshore petroleum section embarked upon a similar project for onshore Australian basins. The purpose of this project is to provide a thorough basis for whole of basin information to advise the Australia Government and other stakeholders, such as the petroleum industry, regarding the exploration status and prospectivity of onshore Australian basins. Eight onshore Australian basins have been selected for this volume and these include: the McArthur, South Nicholson, Georgina, Amadeus, Warburton, Wiso, Galilee and Cooper basins. This record provides a comprehensive whole of basin inventory of the geology, petroleum systems, exploration status and data coverage for these eight onshore Australian basins. It draws on precompetitive work programs by Geoscience Australia as well as publicly available exploration results and geoscience literature. Furthermore, the record provides an assessment of issues and unanswered questions and recommends future work directions to meet these unknowns.

Publicly available geological data in the north Bowen Basin region are compiled to produce statements of existing knowledge for natural hydrogen, hydrogen storage, coal and mineral occurrences. This data guide also contains assessment of the potential for carbon dioxide (CO2) geological storage and minerals in the basin region. Geochemical analyses of gas samples from petroleum, coal and coal seam gas boreholes in the basin show traces of natural hydrogen. However, the generation mechanism of the observed natural hydrogen concentration is unknown. Numerous mineral occurrences are found in the basin. Most contain gold, which historically has often been mined. Most occurrences are small, with some exceptions, such as Cracow, Golden Plateau, Kauffman’s Prospect and Miclere gold deposits. The north Bowen Basin has potential for epithermal gold-silver and gold-copper deposits in the deeper formations, but the depth of much of the basin makes exploration and mining difficult and expensive. There is also potential for sandstone-hosted uranium and paleoplacer gold deposits in the upper coal-bearing formations, such as what is seen in the Miclere area. The north Bowen Basin has a significant quantity of coal, with 152 deposits found in the basin, totalling about 47 billion tonnes of black coal. The results of CO2 geological storage assessment of 3 play intervals in the north Bowen Basin suggest there is low storage potential within the basin.

Statements of existing knowledge are compiled for known mineral, coal, hydrocarbon and carbon capture and storage (CCS) resources and reserves in the Adavale Basin. This data guide illustrates the current understanding of the distribution of these key resource types within the Adavale Basin region based on trusted information sources. It provides important contextual information on the Adavale Basin and where additional details on discovered resources can be found. So far, mineral deposits have not been found in the Adavale Basin. There are no coal deposits found in the basin itself, but 6 large coal deposits exist in the overlying basins in the Adavale Basin region. Historically, some small conventional gas resources have been found in the basin. Currently, there are no commercial reserves or available resources identified in the Adavale Basin itself. There are no active or planned carbon capture and storage (CCS) projects in the Adavale basin.

Statements of existing knowledge are compiled for known mineral, coal, hydrocarbon and carbon capture and storage (CCS) resources and reserves in the Cooper Basin. This data guide illustrates the current understanding of the distribution of these key resource types within the Cooper Basin region based on trusted information sources. It provides important contextual information on the Cooper Basin and where additional details on discovered resources can be found. To date, mineral or coal deposits have not been found in the Cooper Basin, due to its depth. There are significant hydrocarbon resources found in the basin, including conventional and unconventional hydrocarbons. The Cooper Basin has been a major producer of oil and gas since the 1960s (Smith, Cassel and Evans, 2015). It is one of the largest sources of onshore hydrocarbon production in Australia. Some of the largest unconventional gas resources are contained in the basin. This is mostly basin-centred gas. The geology in the Cooper Basin is considered suitable for use in Carbon Capture and Storage (CCS) projects. The Cooper Basin and overlying Eromanga Basin contain 2 CCS projects that are currently being developed.

Statements of existing knowledge are compiled for known mineral, coal, hydrocarbon and carbon capture and storage (CCS) resources and reserves in the north Bowen Basin. This data guide illustrates the current understanding of the distribution of these key resource types within the north Bowen Basin region based on trusted information sources. It provides important contextual information on the north Bowen Basin and where additional details on discovered resources can be found. The north Bowen Basin contains 17 metallic mineral deposits, with the majority containing gold. The basin also contains 152 thermal and metallurgical coal deposits. Most coal deposits contain metallurgical coal. This basin contains most of Queensland’s metallurgical coal resources, although many of the deposits supply a mix of thermal and metallurgical coal (Blake et al., 2018). The north Bowen Basin hosts very large coal tonnages, with known black coal resources of approximately 47 billion tonnes. Significant hydrocarbon resources are known to exist in the basin, the majority being coal seam gas (CSG). The basin contains more limited reserves and resources of conventional oil and gas and oil shale. At this time, there are no active or planned CCS projects in the basin.
