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, and environmental and regulatory decisions in the Adavale 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 Adavale Basin. The geological storage assessment for the Adavale Basin encompasses 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) to inform the 4 components required for a potential geological storage of CO2 system. Thirty-nine boreholes in the Adavale 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 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 prospective geological storage of CO2 system are 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 and basin scale. As an example of assessments contained within the data package, this data guide showcases the geological storage of CO2 prospectivity in the Gumbardo Play interval.

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 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, 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 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 Adavale Basin. The conventional hydrocarbon assessment for the Adavale Basin includes 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) to inform the 5 components required for conventional 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 conventional hydrocarbon assessments. From these datasets, the following properties have been 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 are explained and mapped. These data were then merged and spatially multiplied to show the relative assessment of conventional 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 conventional hydrocarbon prospectivity of the Lissoy-Bury Play interval.
