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 geological data in the Adavale Basin region are compiled to produce statements of existing knowledge for natural hydrogen, hydrogen storage, coal and mineral occurrences. This data guide also contains an assessment of the potential for carbon dioxide (CO2) geological storage and minerals in the basin region. Geochemical analysis of gas samples from petroleum boreholes in the basin shows various concentrations of natural hydrogen. However, the generation mechanism of the observed natural hydrogen concentration is still unknown. The Adavale Basin also has the potential for underground hydrogen storage in the Boree Salt. Given the depth of the Boree Salt (wells have intersected the salt at depths below 1800 m) and the high fluid pressure gradient in the basin, the construction of underground salt caverns should include consideration of stability and volume shrinkage. Mineral occurrences are all found in the basins overlying the Adavale region. However, they are small (thousands of tonnes range) and not currently of economic interest. The Adavale Basin has potential for base and precious metal deposits due to suitable formation conditions, but the depth of the basin makes exploration and mining difficult and expensive. There are no identified occurrences or resources of coal in the Adavale Basin. Given the depth of the basin, extraction of any identified coal would probably be uneconomic, with the potential exception of coal seam gas extraction. An assessment of CO2 geological storage also shows prospective storage areas in the Eromanga Basin within the Adavale Basin region in the Namur-Murta and Adori-Westbourne play intervals.

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 groundwater data have been compiled to provide a common information base to inform environmental, resource development and regulatory decisions in the Adavale Basin region.

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.
