Statements of existing knowledge are compiled for known mineral, coal, hydrocarbon and carbon capture and storage (CCS) resources and reserves in the Galilee Basin region. This data guide illustrates the current understanding of the distribution of these key resource types within the Galilee Basin region based on trusted information sources. It provides important contextual information on the Galilee Basin and where additional details on discovered resources can be found. The Galilee Basin region contains 6 known metallic mineral deposits, with most of these containing the critical mineral vanadium. There are 17 coal deposits found in the basin containing thermal and metallurgical coal. The primary form of coal in the deposits is thermal coal. The Galilee Basin hosts large coal tonnages, with known black coal resources of approximately 33 billion tonnes. The Galilee Basin and overlying basins are known to contain significant hydrocarbon resources. The majority of the known hydrocarbon resources are found in the Julia Creek oil shale deposits located in the Eromanga Basin above the Galilee Basin. Moderate coal seam gas (CSG) resources have also been identified in the basin; however, conventional gas resources are more limited. At this time, there are no active or planned Carbon Capture and Storage (CCS) projects in the basin.

This web service shows the spatial locations of potential CO2 storage sites that are at an advanced stage of characterisation and/or development. The areas considered to be at an advanced stage are parts of the Cooper Basin in central Australia, a portion of the Surat Basin (Queensland), the offshore Gippsland Basin (Victoria), where the CarbonNet Project is currently at an advanced stage of development and the Petrel Sub-basin. This service will be presented in the AusH2 Portal.

Publicly available geological data in the Cooper Basin region are compiled to produce statements of existing knowledge for natural hydrogen, hydrogen storage, coal and mineral occurrences. This data guide also contains assessment of the potential for carbon dioxide (CO2) geological storage and minerals in the basin region. Geochemical analysis of gas samples from petroleum in the basin shows various concentrations of natural hydrogen. However, the generation mechanism of the observed natural hydrogen concentration is still unknown. The mineral occurrences are all found in the overlying basins and are small and of little economic significance. The Cooper Basin has some potential for base metal and uranium deposits due to somewhat suitable formation conditions, but the depth of the basin makes exploration and mining difficult and expensive. This also applies to coal, where there are no identified occurrences or resources in the Cooper Basin. However, if some were identified, the depth of the basin would probably make extraction uneconomic, with the potential exception of coal seam gas extraction. CO2 geological storage assessment in the overlying Eromanga Basin suggests that most areas over the Cooper Basin (except over the Weena Trough in the south-west) are prospective for geological storage CO2.

Internationally, the number of carbon capture and storage (CCS) projects has been increasing with more than 61 new CCS facilities added to operations around the globe in 2022, including six projects in Australia (GCCSI, 2022). The extraction of reservoir fluid will be an essential component of the CCS workflow for some of projects in order to manage reservoir pressure variations and optimise the subsurface storage space. While we refer to reservoir fluid as brine throughout this paper for simplicity, reservoir fluids can range from brackish to more saline (briny) water. Brine management requires early planning, as it has implications for the project design and cost, and can even unlock new geological storage space in optimal locations. Beneficial use and disposal options for brine produced as a result of carbon dioxide (CO2) storage has been considered at a regional or national scale around the world, but not yet in Australia. For example, it may be possible to harvest energy, water, and mineral resources from extracted brine. Here, we consider how experiences in brine management across other Australian industries can be transferred to domestic CCS projects.

Statements of existing knowledge are compiled for known mineral, coal, hydrocarbon and carbon capture and storage (CCS) resources and reserves in the Cooper Basin. This data guide illustrates the current understanding of the distribution of these key resource types within the Cooper Basin region based on trusted information sources. It provides important contextual information on the Cooper Basin and where additional details on discovered resources can be found. To date, mineral or coal deposits have not been found in the Cooper Basin, due to its depth. There are significant hydrocarbon resources found in the basin, including conventional and unconventional hydrocarbons. The Cooper Basin has been a major producer of oil and gas since the 1960s (Smith, Cassel and Evans, 2015). It is one of the largest sources of onshore hydrocarbon production in Australia. Some of the largest unconventional gas resources are contained in the basin. This is mostly basin-centred gas. The geology in the Cooper Basin is considered suitable for use in Carbon Capture and Storage (CCS) projects. The Cooper Basin and overlying Eromanga Basin contain 2 CCS projects that are currently being developed.
