Publicly available data was compiled to provide a common information base for resource development, and environmental and regulatory decisions in the Eromanga 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 Eromanga Basin. The geological storage of CO2 assessment for the Eromanga Basin overlying the Cooper, Adavale and Galilee basins encompasses 6 of the 9 geological intervals, termed plays – these intervals have been defined by Wainman et al. (2023a, b). The assessment captures data from the Great Artesian Basin geological and hydrogeological surfaces update (Vizy and Rollet, 2022), 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); Bradshaw et al. (2009) and Draper (2002) along with the scientific literature to inform the 4 components required for a prospective geological storage of CO2 system. These datasets are used to map out gross depositional environments and their geological properties relevant for geological storage of CO2 assessments. 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 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 merged and spatially multiplied to show the relative assessment of geological storage of CO2 prospectivity across the basin, both at 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 Namur-Murta Play interval.

The data guide is designed to support the data package that provide insights on the geological storage of CO2 in the Cooper Basin. The geological storage of CO2 assessment for the Cooper Basin encompasses 4 of the 6 geological intervals, termed plays – these intervals have been defined by Wainman et al. (2023). The assessment captures data from the Great Artesian Basin geological and hydrogeological surfaces update (Vizy and Rollet, 2022), Cooper Region Shale, tight and deep coal gas prospectivity of the Cooper Basin (Lech et al., 2020) (GBA), Cooper Basin architecture and lithofacies: Regional hydrocarbon prospectivity of the Cooper Basin (Hall et al., 2015) (CBAL), National Geoscience Mapping Accord Cooper and Eromanga Basins, Australia, seismic mapping data sets (NGMA, 2002), Queensland Petroleum Exploration Database (QPED) from the Geological Survey of Queensland (GSQ) Open Data Portal (2020a), and the Petroleum Exploration and Production System of South Australia (PEPS, 2021) along with the scientific literature to inform the 4 components required for a potential geological storage of CO2 system.

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 working geological storage of CO2 system is 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 interval and basin scale. As an example of assessments contained within the data package, this data guide showcases the geological storage of CO2 prospectivity the Toolachee Play interval.

<div>Carbon capture and storage (CCS) is gaining momentum globally. The Global CCS Institute notes in their Status of CCS 2023 report that there are 26 carbon capture and storage projects under construction and a further 325 projects in development, with a total capture capacity of 361 million tonnes per year (Mt/y) of carbon dioxide (CO2). Some CCS projects require the extraction of brackish or saline water (referred to here on in as brine) from the storage formation to manage increased pressure resulting from CO2 injection and/or to optimise subsurface storage space. It is important to consider the management of extracted brine as the CCS industry scales up due to implications for project design, cost and location as well as for the responsible management of the ‘waste’ or by-product brine. The use and disposal of reservoir brine has been investigated for CCS projects around the world, but not for Australian conditions. We have undertaken this review to explore how extracted brine could potentially be managed by CCS projects across Australia.&nbsp;</div>

Publicly available data was compiled to provide a common information base for resource development, and environmental and regulatory decisions in the north Bowen 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 north Bowen Basin. The geological storage of CO2 assessment for the north Bowen Basin encompasses 3 of the 5 geological intervals, termed plays – these have been defined by Wainman et al. (2023). The assessment captures data from the Queensland Petroleum Exploration Database (QPED) from the Geological Survey of Queensland (GSQ) Open Data Portal (Queensland Government, 2022a); the Queensland Carbon Dioxide Geological Storage Atlas (Bradshaw et al., 2009), ZeroGen IGCC with CCS: A Case History (Garnett et al., 2014), OzSEEBASE (2021) and the Bowen and Surat Basins Regional Structural Framework Study (SRK Consulting, 2008) along with the scientific literature to inform the four components required for a potential geological storage of carbon dioxide system. These datasets were used to map out gross depositional environments and their geological properties relevant for geological storage of carbon dioxide. 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.

In May 2013, Geoscience Australia, in collaboration with the Australian Institute of Marine Science, undertook a marine survey of the Leveque Shelf (survey number SOL5754/GA0340), a sub-basin of the Browse Basin. This survey provides seabed and shallow geological information to support an assessment of the CO2 storage potential of the Browse sedimentary basin. The basin, located on the Northwest Shelf, Western Australia, was previously identified by the Carbon Storage Taskforce (2009) as potentially suitable for CO2 storage. The survey was undertaken under the Australian Government's National CO2 Infrastructure Plan (NCIP) to help identify sites suitable for the long term storage of CO2 within reasonable distances of major sources of CO2 emissions. The principal aim of the Leveque Shelf marine survey was to look for evidence of any past or current gas or fluid seepage at the seabed, and to determine whether these features are related to structures (e.g. faults) in the Leveque Shelf area that may extend to the seabed. The survey also mapped seabed habitats and biota to provide information on communities and biophysical features that may be associated with seepage. This research, combined with deeper geological studies undertaken concurrently, addresses key questions on the potential for containment of CO2 in the basin's proposed CO2 storage unit, i.e. the basal sedimentary section (Late Jurassic and Early Cretaceous), and the regional integrity of the Heyward Formation (the seal unit overlying the main reservoir). The survey collected one hundred and eleven seabed sediment samples that were analysed for their grain size, textural composition and carbonate content. This dataset includes the results of grain size analysis measured by laser diffractometer.
