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 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.
