Publicly available data was compiled to provide a common information base for resource development, environmental and regulatory decisions in the north Bowen Basin. This data guide gives an example of how these data can be used to create the components of a workflow to identify unconventional hydrocarbon resource opportunities. The data guide is designed to support the data package that provide insights on unconventional hydrocarbon resources in the north Bowen Basin. The unconventional hydrocarbon assessment for the north Bowen Basin includes tight gas, shale resources (shale oil and gas) and coal seam gas (CSG) for 4 geological intervals, termed plays – these intervals have been defined by Wainman et al. (2023). The assessment captures data from well completion reports and government data sources, including the Bowen and Surat Basins Regional Structural Framework Study (SRK Consulting, 2008), Rangal Supermodel 2015: Rangal-Baralaba-Bandanna Coal Measures in the Bowen and Galilee Basins (Sliwa et al., 2017), Queensland Petroleum Exploration Database (QPED) from the Geological Survey of Queensland (GSQ) Open Data Portal (2020a), Coal Maturity Trends within the Bowen Basin (McKillop, 2016), and Rapid regional prioritisation for tight and shale gas potential of eastern and northern Australian basins (Hall et al., 2018) along with the scientific literature to inform the components required for unconventional hydrocarbons to be present. These datasets were used to map out gross depositional environments and their geological properties relevant for unconventional hydrocarbon assessments. The data are compiled at a point in time to inform decisions on resource development activities. The data guide outlines the play-based workflow for assessing unconventional hydrocarbon resource prospectivity. Each of the elements required for a prospective unconventional hydrocarbon system is explained and mapped. These data were merged and spatially multiplied to show the relative assessment of unconventional hydrocarbon prospectivity across the basin, at both the play interval and basin scale. As an example of assessments contained within the data package, this data guide showcases the CSG prospectivity of the Rewan–Blackwater Play interval.

Publicly available groundwater data have been compiled to provide a common information base to inform environmental, resource development and regulatory decisions in the north Bowen Basin region. This data guide gives examples of how these data can be used. The data package included with this data guide captures existing knowledge of near-surface groundwater resources in north Bowen Basin, including salinity, water levels, resource size and surface water interactions. The methods used to derive these data for the shallow groundwater in the north Bowen Basin are outlined in the associated metadata files. These are described in groundwater conceptual models (Hostetler et al., 2023). Groundwater data for the north Bowen Basin are restricted to the upper 50 m, as a stratigraphic model is not available. Compiled data are assigned to this interval and used to characterise the near-surface groundwater system at the basin scale. The data are compiled for a point-in-time to inform decisions on potential resource developments in the Basin. The available historical groundwater data can be used to assess the potential effects on groundwater. The data can also be used for other purposes, such as exploring unallocated groundwater resource potential. Data to January 2022 are used for this compilation.

Publicly available geological data in the Galilee 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. The mineral occurrences are mostly found in the overlying basins, and they are often small and of little economic significance. There are some exceptions, such as the Lilyvale vanadium deposit found in the northern Galilee region, in the overlying Eromanga Basin. The Galilee Basin has limited potential for uranium and precious metal deposits due to relative lack of suitable formation conditions, but the depth of much of the basin makes exploration and mining difficult and expensive. There are some large coal measures found in the Galilee Basin, with 17 deposits in the Galilee and overlying Eromanga basins, containing about 38 billion tonnes of black coal. An assessment of geological storage of CO2 potential suggests the Galilee Basin Betts Creek - Rewan Play is the most prospective for storing CO2, with the highest potential around the central basin region. There are no reports of natural hydrogen in the Galilee Basin.

Publicly available baseline ecology data are compiled to provide a common information base for environment, resource development and regulatory decisions in the north Bowen Basin region. This data guide captures existing knowledge of the ecosystems and environmental assets overlying the north Bowen Basin. The land overlying the north Bowen Basin is dominated by the Brigalow Belt North and South Interim Biogeographic Regionalisation for Australia (IBRA) bioregions. The data on the ecosystems and environmental assets overlying the North Bowen Basin have been summarised in July 2021 to inform decisions on resource development activities. Key data sources are broad vegetation groups - pre-clearing and 2019 remnant - Queensland series (Queensland Government), Field Environmental Data, Australian Wetlands Database and Heritage places and lists (Department of Climate Change, Energy, the Environment and Water), and the Atlas of Living Australia.

Publicly available data was compiled to provide a common information base for resource development, and environmental and regulatory decisions in the Cooper Basin. This data guide gives examples of how these data can be used to create the components of a workflow to identify geological storage of carbon dioxide (CO2) opportunities. The data guide is designed to support the data package that provide insights on the geological storage of CO2 in the Cooper Basin. The geological storage of CO2 assessment for the Cooper Basin encompasses 4 of the 6 geological intervals, termed plays – these intervals have been defined by Wainman et al. (2023). The assessment captures data from the Great Artesian Basin geological and hydrogeological surfaces update (Vizy and Rollet, 2022), Cooper Region Shale, tight and deep coal gas prospectivity of the Cooper Basin (Lech et al., 2020) (GBA), Cooper Basin architecture and lithofacies: Regional hydrocarbon prospectivity of the Cooper Basin (Hall et al., 2015) (CBAL), National Geoscience Mapping Accord Cooper and Eromanga Basins, Australia, seismic mapping data sets (NGMA, 2002), Queensland Petroleum Exploration Database (QPED) from the Geological Survey of Queensland (GSQ) Open Data Portal (2020a), and the Petroleum Exploration and Production System of South Australia (PEPS, 2021) along with the scientific literature to inform the 4 components required for a potential geological storage of CO2 system. These datasets are used to map out geological properties relevant for geological storage of CO2 assessments. From these datasets, the following properties have been evaluated and mapped across the basin: injectivity, storage efficiency, containment and structural complexity. The data are compiled at a point in time to inform decisions on resource development opportunities. The data guide outlines the play-based workflow for assessing geological storage of CO2 prospectivity. Each of the elements required for a working geological storage of CO2 system is explained and mapped. These data were then merged and spatially multiplied to show the relative assessment of geological storage of CO2 prospectivity across the basin, at both play interval and basin scale. As an example of assessments contained within the data package, this data guide showcases the geological storage of CO2 prospectivity the Toolachee Play interval.

The potential for hydrogen production in the Adavale Basin region is assessed to provide a joint information base for hydrogen generation potential from renewable energy, groundwater, and natural gas coupled with carbon capture and storage (CCS). Hydrogen generation requires water, whether using electrolysis with renewable energy or steam methane reforming (SMR) with CCS. The data package includes the regional renewable energy capacity factor, aquifers and their properties (potential yield, salinity, and reserves or storativity), natural gas resources, and geological storage potential for carbon dioxide (CO2). This data guide gives examples of how the compiled data can be used. The renewable hydrogen potential is assessed based on renewable energy capacity factor and groundwater information (potential yield, salinity, and reserves or storativity). Eight aquifers from overlying basins (Galilee, Eromanga and Lake Eyre basins) are included in the assessment. The Adavale Basin region has low renewable hydrogen potential, except for some locations in the south-east and south-west. Although the renewable energy capacity factor in the basin is high, aquifers tend to have poor groundwater reserves or storativity, which results in lower overall renewable hydrogen potential. The Adavale Basin itself has no newly identified gas accumulation. However, gas reserves and contingent resources were identified in the overlying Galilee and Eromanga basins (Geoscience Australia, 2022). An assessment of CO2 geological storage also shows prospective storage areas in the Eromanga Basin within the Adavale Basin region (Bradshaw et al., 2023). Further work on identifying detailed gas potential is needed to assess hydrogen generation potential from gas.

Publicly available geological data in the Cooper 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 analysis of gas samples from petroleum in the basin shows various concentrations of natural hydrogen. However, the generation mechanism of the observed natural hydrogen concentration is still unknown. The mineral occurrences are all found in the overlying basins and are small and of little economic significance. The Cooper Basin has some potential for base metal and uranium deposits due to somewhat suitable formation conditions, but the depth of the basin makes exploration and mining difficult and expensive. This also applies to coal, where there are no identified occurrences or resources in the Cooper Basin. However, if some were identified, the depth of the basin would probably make extraction uneconomic, with the potential exception of coal seam gas extraction. CO2 geological storage assessment in the overlying Eromanga Basin suggests that most areas over the Cooper Basin (except over the Weena Trough in the south-west) are prospective for geological storage CO2.

Publicly available data was compiled to provide a common information base for resource development, and environmental and regulatory decisions in the Adavale Basin. This data guide gives examples of how these data can be used to create the components of a workflow to identify geological storage of carbon dioxide (CO2) opportunities. The data guide is designed to support the data package that provide insights on the geological storage of CO2 in the Adavale Basin. The geological storage assessment for the Adavale Basin encompasses 8 geological intervals, termed plays – these intervals have been defined by Wainman et al. (2023). The assessment captures data from well completion reports and government data sources (e.g. Queensland Petroleum Exploration Database (QPED) from the Geological Survey of Queensland (GSQ) Open Data Portal) to inform the 4 components required for a potential geological storage of CO2 system. Thirty-nine boreholes in the Adavale Basin were used to map out gross depositional environments and their geological properties relevant for geological storage of CO2. From these datasets, the following properties have been evaluated and mapped across the basin: injectivity, storage efficiency, containment and structural complexity. The data are compiled at a point in time to inform decisions on resource development opportunities. The data guide outlines the play-based workflow for assessing geological storage of CO2 prospectivity. Each of the elements required for a prospective geological storage of CO2 system are explained and mapped. These data were then merged and spatially multiplied to show the relative assessment of geological storage of CO2 prospectivity across the basin at both play and basin scale. As an example of assessments contained within the data package, this data guide showcases the geological storage of CO2 prospectivity in the Gumbardo Play interval.

Publicly available groundwater data have been compiled to provide a common information base to inform environmental, resource development and regulatory decisions in the Cooper Basin region. This data guide gives examples of how these data can be used. The data package included with this data guide captures existing knowledge of Eromanga Basin aquifers and their properties, including salinity, water levels, resource size, potential aquifer yield and surface water interactions. The methods used to derive these data for all Eromanga Basin aquifers in the Cooper Basin region are outlined in the associated metadata files. These are described in groundwater conceptualisation models (Gouramanis et al., 2023). The Eromanga Basin overlying the Cooper Basin includes 5 broadly defined aquifer intervals: from deepest to shallowest, these are the Poolowanna, Hutton, Adori, Cadna-owie-Hooray and Winton-Mackunda aquifers. Compiled data are assigned to these intervals and used to characterise groundwater systems at the basin scale. The data were compiled for a point-in-time to inform decisions on potential resource developments in the Basin. The available historical groundwater data can be used to assess the potential effects on groundwater. The data can also be used for other purposes, such as exploring unallocated groundwater resource potential. Data to January 2022 are used for this compilation.
