Publicly available data was compiled to provide a common information base for resource development, environmental and regulatory decisions in the Galilee 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 Galilee Basin. The unconventional hydrocarbon assessment for the Galilee Basin includes tight gas, shale resources (shale oil and gas) and coal seam gas (CSG) for 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) along with the scientific literature to inform the components required for unconventional hydrocarbons to be present. One hundred and sixty-three boreholes in the Galilee 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 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 Betts CreekRewan Play interval.

Publicly available geology data are compiled to provide a common information base for resource development, environmental and regulatory decisions in the Cooper Basin region. This data guide gives examples of how these data can be used and supports the data package that provides the existing knowledge of the key geological intervals of the Cooper Basin and the overlying Eromanga and Lake Eyre basins. The key geological intervals identified by the Trusted Environmental and Geological Information (TEGI) Program for resource assessment and groundwater system characterisation are termed play intervals and hydrostratigraphic intervals respectively. The Cooper Basin includes 7 plays, which are consolidated into 1 hydrostratigraphic interval. Overlying the Cooper Basin are 9 play intervals of the Eromanga Basin, which are consolidated into 7 hydrostratigraphic intervals and 1 Cenozoic play interval and 1 hydrostratigraphic interval for the Lake Eyre Basin. The geological groups and formations included in the play and hydrostratigraphic intervals are summarised in the stratigraphic charts of Wainman et al. (2023). Gross depositional, depth structure and thickness maps are provided with 3D model and cross-sections summarising the geology of the Cooper Basin and the overlying basins. The mapped depths and thicknesses of the key intervals are used to inform resource assessments and provide the framework for assigning groundwater data to hydrostratigraphic intervals.

Publicly available geology data are compiled to provide a common information base for resource development, environmental and regulatory decisions in the Adavale Basin region. This data guide gives examples of how these data can be used and supports the data package that provides the existing knowledge of the key geological intervals of the Adavale Basin and the overlying Galilee, Eromanga and Lake Eyre basins. The key geological intervals identified by the Trusted Environmental and Geological Information (TEGI) Program for resource assessment and groundwater system characterisation are termed play intervals and hydrostratigraphic intervals respectively. The Adavale Basin includes 8 plays, which are consolidated into 1 hydrostratigraphic interval. Overlying the Adavale Basin are 5 play intervals of the Galilee Basin, which are consolidated into 3 hydrostratigraphic intervals; 9 play intervals of the Eromanga Basin, which are consolidated into 7 hydrostratigraphic intervals; and 1 Cenozoic play interval and 1 hydrostratigraphic interval for the Lake Eyre and other Cenozoic basins. The geological groups and formations included in the plays and hydrostratigraphic intervals are summarised in the stratigraphic charts of Wainman et al. (2023a). Gross depositional, depth structure and thickness maps are provided with 3D model and cross-sections summarising the geology of the Adavale Basin and the overlying basins. The mapped depths and thicknesses of the key intervals are used to inform resource assessments and provide the framework for assigning groundwater data to hydrostratigraphic intervals.

Publicly available baseline surface water data are compiled to provide a common information base for resource development and regulatory decisions in the Cooper Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the Cooper Basin, including streamflow quality and quantity, inundation, and climatological data. The Cooper Basin underlies 3 surface water catchments: the Diamantina River, Cooper Creek and Bulloo River. All 3 rivers follow a similar flow pattern, with most of the run-off generated in the higher rainfall headwater areas (outside the Cooper Basin) before flowing down into extensive floodplains and ending up in terminal lake systems. The data on the catchments overlying the Cooper 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.

Publicly available baseline surface water data are compiled to provide a common information base for resource development and regulatory decisions in the north Bowen Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the north Bowen Basin, including streamflow quality and quantity, inundation and climatological data. Most of the north Bowen Basin falls to the east of the Great Dividing Range within the Fitzroy River catchment. The basin also includes part of the Burdekin River catchment and small parts of the coastal catchments of Styx and Burnett river catchments. The data on the catchments overlying the north Bowen Basin have been summarised at a point in time to inform decisions on resource development activities. Key data sources are available from the Water Monitoring Information Portal (Queensland Government), Water Data Online (Bureau of Meteorology), DEA Water Observations (Geoscience Australia) and Terrestrial Ecosystem Research Network.

Publicly available geology data are compiled to provide a common information base for resource development and regulatory decisions in the Galilee 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 Galilee Basin and the overlying Eromanga, Lake Eyre and other Cenozoic basins. Stratigraphic frameworks capture the geological groups and formations that make up the sedimentary sequence in the Galilee Basin region. The Galilee Basin includes 4 stratigraphic groups. From deepest to shallowest, these are the Joe Joe Group, Betts Creek group, Rewan Group and Clematis Group. Overlying the Galilee Basin are the geological formations of the 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 Galilee Basin to the top of overlying Cenozoic basins, the sedimentary sequence is categorised into 15 play intervals for resource assessment mapping and 11 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 Galilee Basin region geological, resource and environmental assessments.

Publicly available data was compiled to provide a common information base for resource development, environmental and regulatory decisions in the Galilee 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 hydrocarbon resources in the Galilee Basin. The conventional hydrocarbon assessment for the Galilee Basin includes oil and gas resources for 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) to inform the 5 components required for conventional hydrocarbons to be present. One hundred and sixty-three boreholes in the Galilee Basin were assessed with data 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 guide outlines the play-based workflow for assessing conventional hydrocarbon resource prospectivity. Each of the elements required for a working unconventional hydrocarbon system is explained and mapped. These data are integrated and merged to show the relative assessment of 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 conventional hydrocarbon prospectivity of the Jericho 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 Galilee 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 Galilee Basin aquifers and their properties, including salinity, water levels, resource size, potential aquifer yield and surface water - groundwater interactions. The methods used to derive these data for all Galilee Basin aquifers in the Galilee Basin region are outlined in the associated metadata files. These are described in groundwater conceptual models (Hostetler et al., 2023). The Galilee Basin includes 3 broadly defined aquifer intervals: from deepest to shallowest, these are the Joe Joe Group, Betts Creek beds and Clematis aquifers. Compiled data have been 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 were used for this compilation.

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.
