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 conventional hydrocarbon resource (oil and gas) opportunities. The data guide is designed to support the data package that provide insights on conventional oil and gas resources in the north Bowen Basin. The conventional hydrocarbon assessment for the north Bowen Basin includes 4 of the 5 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 and the Bowen and Surat Basins Regional Structural Framework Study (SRK Consulting, 2008)) to inform the 5 components required for conventional hydrocarbons to be present. These datasets are used to map out gross depositional environments and their geological properties relevant for conventional hydrocarbon assessments. From these datasets, the following properties were evaluated and mapped across the basin: reservoir presence, reservoir effectiveness, top seal, trap and charge. 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 conventional hydrocarbon resource prospectivity. Each of the elements required for a prospective conventional hydrocarbon system is explained and mapped. These data were merged and spatially multiplied to show the relative assessment of conventional hydrocarbon prospectivity across the north Bowen Basin, at both the play interval and basin scale. As an example of assessments contained within the data package, this data guide showcases the conventional hydrocarbon prospectivity of the Upper Back Creek Play interval.

Publicly available geology data are compiled to provide a common information base for resource development and regulatory decisions in the Adavale 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 Adavale Basin and the overlying Galilee, Eromanga, Lake Eyre and other Cenozoic basins. Stratigraphic frameworks capture the geological groups and formations that make up the sedimentary sequence in the Adavale Basin region. The Adavale Basin includes 9 stratigraphic formations (Wainman et al., 2023). Overlying the Adavale Basin are the geological formations of the Galilee, Eromanga, Lake Eyre and other Cenozoic basins. The frameworks include the stratigraphic intervals used by the Trusted Environmental and Geological Information (TEGI) Program. From the base of the Adavale Basin to the top of overlying Cenozoic basins, the sedimentary sequence is categorised into 24 play intervals for resource assessment mapping and 12 hydrostratigraphic intervals for characterising groundwater systems (Wainman et al., 2023). 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 Adavale Basin region resource and environmental assessments.

Publicly available data was compiled to provide a common information base for resource development, environmental and regulatory decisions in the Adavale 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 Adavale Basin. The unconventional hydrocarbon assessment for the Adavale Basin includes tight gas, shale resources (shale oil and gas) and coal seam gas for 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) along with the scientific literature to inform the components required for unconventional hydrocarbons to be present. Thirty-nine boreholes in the Adavale Basin were assessed with data 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 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 play interval and basin scale. As an example of assessments contained within the data package, this data guide showcases the tight gas prospectivity of the Buckabie Play interval.

Publicly available data was compiled to provide a common information base for resource development, environmental and regulatory decisions in the Eromanga Basin region. 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 Eromanga Basin. The unconventional hydrocarbon assessment for the Eromanga Basin includes shale resources (shale oil and gas) and coal seam gas for 6 of the 9 geological intervals, termed plays – these intervals have been defined by Wainman et al. (2023a, 2023b). Tight gas was not assessed due to play intervals lying above the zone of significant overpressure zone (2,800 m below ground level) in the Cooper-Eromanga region. The assessment captures data from well completion reports and government data sources to inform the components required for unconventional hydrocarbons to be present in the Eromanga Basin. The assessment captures data from the Great Artesian Basin geological and hydrogeological surfaces update (Vizy and Rollet, 2022), the 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) and Draper 2002. 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 will outline the play-based workflow for assessing unconventional hydrocarbon prospectivity. Each of the elements required for a prospective unconventional hydrocarbon system is explained and mapped. These data are integrated and merged to show the relative assessment of unconventional prospectivity across the basin, at both play interval and basin scale. As an example of assessments contained within the dataset, this data guide showcases the prospectivity of shale resources in the Birkhead Play interval.

Publicly available geology data are compiled to provide a common information base for resource development and regulatory decisions in the Cooper 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 Cooper Basin and the overlying Simpson, Eromanga and Lake Eyre basins. Stratigraphic frameworks capture the geological groups and formations that make up the sedimentary sequence in the Cooper Basin region. The Cooper Basin includes 2 stratigraphic groups. From deepest to shallowest, these are the Gidgealpa Group and the Nappamerri Group. The overlying Cuddapan Formation is considered part of the Simpson Basin instead of the Cooper Basin. Overlying the Cooper Basin are the geological formations of the Eromanga and Lake Eyre basins. The frameworks include the stratigraphic intervals used by the Trusted Environmental and Geological Information (TEGI) Program. From the base of the Cooper Basin to the top of the Lake Eyre Basin, the sedimentary sequence is categorised into 16 play intervals for resource assessment mapping and 9 hydrostratigraphic intervals for characterising groundwater systems (Wainman et al., 2023). 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 Cooper Basin region geological, resource and environmental assessments.

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.

The methods to derive these data for all Adavale Basin aquifers are outlined in the associated metadata files. These are described in groundwater conceptual models (Gouramanis et al., 2023). The Adavale Basin includes multiple aquifer systems that are grouped and more broadly defined as the Adavale Basin aquifers. Compiled data are assigned to these intervals and used to characterise groundwater systems at the basin scale. The data are compiled for a point in time to inform decisions on potential resource developments in the Basin.

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.

This data guide gives examples of how these data can be used. The data package included with this data guide captures existing knowledge of Lake Eyre Basin aquifers in the Adavale Basin region and their properties, including salinity, water levels, resource size, potential aquifer yield and surface water interactions. The methods to derive these data for the Lake Eyre Basin aquifer in the Adavale Basin region are outlined in the associated metadata files. These are described in groundwater conceptual models (Gouramanis et al., 2023). The Lake Eyre Basin overlying the Adavale Basin includes one broadly defined aquifer: Cenozoic hydrostratigraphic unit (Cenozoic aquifer). Compiled data are assigned to these intervals and used to characterise groundwater systems 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.

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.
