The potential for hydrogen production in the Galilee 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), natural gas resources, 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). Nine aquifers from the Galilee and overlying Eromanga and the Lake Eyre basins are included in the assessment. The Galilee Basin region has low renewable hydrogen potential except for small areas in the north, south 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 Galilee Basin contains modest contingent gas resources, while sizeable gas reserves and contingent resources were identified in the overlying Eromanga Basin (Geoscience Australia, 2022). The geological CO2 storage assessment suggests that the Betts Creek - Rewan Play interval is the most prospective for CCS, with the highest potential around the central basin region. Further work on identifying detailed gas potential is needed to assess hydrogen generation potential from gas.

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 Lake Eyre Basin aquifers in the Galilee Basin region and their properties, including salinity, water levels, resource size, potential aquifer yield and indicators of surface water interactions. The methods used to derive these data for the Lake Eyre Basin aquifer in the Galilee Basin region are outlined in the associated metadata files. These are described in groundwater conceptualisation models (Hostetler et al., 2023). The Lake Eyre Basin overlying the Galilee Basin includes one broadly defined aquifer that includes multiple aquifer systems that are defined as Cenozoic aquifers. Compiled data was assigned to this interval and were used to characterise groundwater systems at the basin scale. The data are compiled for a point-in-time to inform decisions on resource development activities Basin. The available historical groundwater data can be used to assess the potential effects on groundwater for different development scenarios. 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 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.

Statements of existing knowledge are compiled for known mineral, coal, hydrocarbon and carbon capture and storage (CCS) resources and reserves in the north Bowen Basin. This data guide illustrates the current understanding of the distribution of these key resource types within the north Bowen Basin region based on trusted information sources. It provides important contextual information on the north Bowen Basin and where additional details on discovered resources can be found. The north Bowen Basin contains 17 metallic mineral deposits, with the majority containing gold. The basin also contains 152 thermal and metallurgical coal deposits. Most coal deposits contain metallurgical coal. This basin contains most of Queensland’s metallurgical coal resources, although many of the deposits supply a mix of thermal and metallurgical coal (Blake et al., 2018). The north Bowen Basin hosts very large coal tonnages, with known black coal resources of approximately 47 billion tonnes. Significant hydrocarbon resources are known to exist in the basin, the majority being coal seam gas (CSG). The basin contains more limited reserves and resources of conventional oil and gas and oil shale. At this time, there are no active or planned CCS projects in the basin.

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.

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

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.
