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.

Publicly available data was compiled to provide a common information base for resource development, and environmental and regulatory decisions in the Eromanga 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 Eromanga Basin. The geological storage of CO2 assessment for the Eromanga Basin overlying the Cooper, Adavale and Galilee basins encompasses 6 of the 9 geological intervals, termed plays – these intervals have been defined by Wainman et al. (2023a, b). The assessment captures data from the Great Artesian Basin geological and hydrogeological surfaces update (Vizy and Rollet, 2022), Queensland Petroleum Exploration Database (QPED) from the Geological Survey of Queensland (GSQ) Open Data Portal (2020a), the Petroleum Exploration and Production System of South Australia (PEPS, 2021); Bradshaw et al. (2009) and Draper (2002) along with the scientific literature to inform the 4 components required for a prospective geological storage of CO2 system. These datasets are used to map out gross depositional environments and their geological properties relevant for geological storage of CO2 assessments. From these datasets, the following properties were 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 merged and spatially multiplied to show the relative assessment of geological storage of CO2 prospectivity across the basin, both at a 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 of the Namur-Murta Play interval.

Publicly available data was compiled to provide a common information base for resource development, and environmental and regulatory decisions in the Galilee 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 Galilee Basin. The geological storage of CO2 assessment for the Galilee Basin encompasses 5 geological intervals, termed plays – these 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. One hundred and sixty-three boreholes in the Galilee 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 were 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 guide outlines the play-based workflow for assessing geological storage of CO2 prospectivity. Each of the elements required for a prospective geological storage of carbon dioxide system are explained and mapped. These data were merged and spatially multiplied to show the relative assessment of geological storage of carbon dioxide prospectivity across the basin at both a 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 of the Betts Creek-Rewan Play interval.

Across Australia, groundwater is a vital resource that supports and strengthens communities, culture, the environment and numerous industries. Movement of groundwater is complicated, taking place horizontally, vertically and across different timescales from weeks to millions of years. It is affected by changes in climate, human use and geological complexities such as the type, geometry and distribution of rocks. Understanding how all these factors interact is known as a groundwater conceptual model and it is an important first step. This groundwater conceptualisation includes the Adavale Basin and the overlying Galilee Basin. Conceptualisation of the Galilee, Eromanga and Lake Eyre basins can be found in Hostetler et al. (2023). In the Adavale Basin this includes 1 aquifer in the Lake Eyre Basin, 5 aquifers in the Eromanga Basin, 3 aquifers in the Galilee Basin and 1 aquifer in the Adavale Basin (Wainman et al., 2023a, b). Confidence for each aquifer was calculated for both salinity and water levels (Gouramanis et al., 2023a, b, c, d). The confidence for each aquifer was added to show the overall confidence for the basin. The level of knowledge across all aquifers are moderate to low. The groundwater conceptualisations summarises the groundwater flow and potential connectivity between aquifers. Figures in this fact sheet show the distribution of the aquifers and aquitards, average salinity, potential aquifer yield and confidence over an area of 50 km along the cross section lines.

The potential for hydrogen production in the Cooper 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) of gas with CCS. The data package includes the regional renewable energy capacity factor, aquifers and their properties (potential yield, salinity, and reserves or storativity), and geological storage potential of 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). Three aquifers from overlying basins (Eromanga and Lake Eyre basins) are included in the assessment. The Cooper Basin region has high renewable hydrogen potential. The presence of good aquifer throughout the basin combined with high renewable energy capacity factor resulted in significant areas with high hydrogen potential. The Cooper Basin has significant hydrocarbon resources, primarily for gas (Geoscience Australia, 2022). Although most known hydrocarbon resources have depleted since production began in the 1960s (Smith et al., 2015), a large amount of gas remains, including conventional gas (1,058 PJ reserves and 1,598 PJ resources) and unconventional basin-centred gas (2,265 PJ resources). An assessment in the overlying Eromanga Basin suggests that most areas over the Cooper Basin are prospective for potential CO2 geological storage (Bradshaw et al., 2023). Further work on identifying detailed gas potential is needed to assess hydrogen generation potential from SMR coupled with CCS.

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.

Publicly available baseline surface water data are compiled to provide a common information base for resource development and regulatory decisions in the Galilee Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the Galilee Basin, including streamflow quality and quantity, inundation, and climatological data. The Galilee Basin straddles the Great Dividing Range and encompasses the headwaters of 9 major river basins, with the largest area underlying Cooper Creek, Diamantina River and Flinders River catchments. The Galilee Basin geological boundary also intersects parts of the catchment of the Burdekin River, Fitzroy River, Warrego River, Bulloo River, Paroo River and Condamine-Balonne rivers. The data on the catchments overlying the Galilee Basin have been summarised at a point in time to inform decisions on resource development activities. Key data sources are the Water Monitoring Information Portal (Queensland Government), Water Data Online (Bureau of Meteorology), DEA Water Observations (Geoscience Australia) and Terrestrial Ecosystem Research Network.

Across Australia, groundwater is a vital resource that supports and strengthens communities, culture, the environment and numerous industries. Movement of groundwater is complicated, taking place horizontally, vertically and across different timescales ranging from weeks to millions of years. It is affected by changes in climate, human use and geological complexities such as the type, geometry and distribution of rocks. Understanding how all these factors interact is known as a groundwater conceptual model and it is an important first step. This groundwater conceptualisation is for the shallow groundwater in the north Bowen Basin as well as surface-groundwater interactions. Figure 1 shows the location of the cross sections used to conceptualise groundwater in the north Bowen Basin region. It also shows the combined (stacked) confidence for both salinity and water levels for the shallow (<50 m below ground surface) groundwater system in the north Bowen Basin. There is no publicly available geological model for the north Bowen Basin extended region. As a result, only the shallow groundwater system is included in this conceptualisation (Wainman et al., 2023). Confidence was calculated for both salinity and water levels (Hostetler et al., 2023) and combined to show overall confidence. The level of knowledge across the extended region is medium to low. The groundwater conceptualisations show the average value of the shallow groundwater, salinity and confidence over an area of 50 km along the cross section line.

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 geology data are compiled to provide a common information base for resource development and regulatory decisions in the north Bowen Basin region. This data guide gives examples of how the compiled data can be used. It supports a data package that presents core photographs, existing knowledge of the stratigraphy, and structural elements for the north Bowen Basin and the overlying Cenozoic basins. Stratigraphic frameworks capture the geological groups and formations that make up the sedimentary sequence in the north Bowen Basin region. The north Bowen Basin has 5 stratigraphic groups. From deepest to shallowest, these are the Lizzie Creek Group, Back Creek Group, Blackwater Group, Rewan Group and Clematis Group. Overlying the north Bowen Basin are the geological formations of Cenozoic basins. The north Bowen Basin has 5 play intervals, which are consolidated into one hydrostratigraphic interval. Overlying the north Bowen Basin are 1 Cenozoic play interval and 1 hydrostratigraphic interval. The geological groups and formations in the play intervals and hydrostratigraphic intervals are summarised in the stratigraphic charts included with this data package. Structural elements maps summarise where the sedimentary sequence has been deposited and later deformed by crustal movements. Structure information is used in assessing the geological potential for resources and interpreting groundwater flow and connectivity at the basin scale. The stratigraphic frameworks and structural elements provide the basic geological context for the north Bowen Basin region geological, resource and environmental assessments.
