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.

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 Eromanga 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 used to derive these data for all Eromanga Basin aquifers in the Adavale Basin region are outlined in the associated metadata files. These are described in groundwater conceptual models (Gouramanis et al., 2023). The Eromanga Basin overlying the Adavale Basin includes 5 broadly defined aquifer intervals: from deepest to shallowest, these are the Poolowanna, Hutton, Adori, Cadna-owie–Hooray and Winton-Mackunda aquifers. 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.

<div>The Pedirka, Simpson and western Eromanga basins in central Australia have undergone a chequered exploration history which has seen a total of only 42 wells drilled across a study area of ~210,000km2. Exploration initially focused on conventional hydrocarbons from the 1950s-1980s, before shifting towards coal seam gas (CSG) opportunities in the mid-2000s. Active petroleum systems have been proven in the region by a non-commercial oil discovery at Poolowanna 1 in 1977, and by several wells that showed evidence of residual oil columns. CSG exploration wells have confirmed the presence of thick, marginally mature coal intervals on the flanks of the basins, but are yet to evaluate the deeper troughs.</div><div>Geoscience Australia, the Northern Territory Geological Survey and the South Australian Department for Energy and Mining have been collaborating on the Australia’s Future Energy Resources project under the Australian government funded Exploring for the Future Program to undertake an assessment of the resource potential for conventional and unconventional hydrocarbons, and the geological carbon and storage (GCS) potential of the greater Pedirka region. </div><div>The project applied a play-based exploration approach to qualitatively assess the resource potential of the region. The Carboniferous to Cretaceous stratigraphic interval was divided into 14 plays which were evaluated for the presence of sediment-hosted energy resources through post-drill analysis, gross depositional environment mapping and common risk segment mapping. The analysis identified energy resources and GCS potential across multiple plays and locations within the study area. These results demonstrate, that while the region is underexplored, it should not be overlooked by future exploration activities.</div> Published in The APPEA Journal 2023. <b>Citation:</b> Iwanec Jeremy, Strong Paul, Bernecker Tom (2023) Underexplored but not forgotten: assessing the energy resources potential of the greater Pedirka Basin region through play-based mapping. <i>The APPEA Journal</i><b> 63</b>, S251-S256. https://doi.org/10.1071/AJ22150
