Publicly available geological data in the Galilee 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. The mineral occurrences are mostly found in the overlying basins, and they are often small and of little economic significance. There are some exceptions, such as the Lilyvale vanadium deposit found in the northern Galilee region, in the overlying Eromanga Basin. The Galilee Basin has limited potential for uranium and precious metal deposits due to relative lack of suitable formation conditions, but the depth of much of the basin makes exploration and mining difficult and expensive. There are some large coal measures found in the Galilee Basin, with 17 deposits in the Galilee and overlying Eromanga basins, containing about 38 billion tonnes of black coal. An assessment of geological storage of CO2 potential suggests the Galilee Basin Betts Creek - Rewan Play is the most prospective for storing CO2, with the highest potential around the central basin region. There are no reports of natural hydrogen in the Galilee Basin.

Following the publication of Geoscience Australia record 2014/09: Petroleum geology inventory of Australia's offshore frontier basins by Totterdell et. al, (2014), the onshore petroleum section embarked upon a similar project for onshore Australian basins. The purpose of this project is to provide a thorough basis for whole of basin information to advise the Australia Government and other stakeholders, such as the petroleum industry, regarding the exploration status and prospectivity of onshore Australian basins. Eight onshore Australian basins have been selected for this volume and these include: the McArthur, South Nicholson, Georgina, Amadeus, Warburton, Wiso, Galilee and Cooper basins. This record provides a comprehensive whole of basin inventory of the geology, petroleum systems, exploration status and data coverage for these eight onshore Australian basins. It draws on precompetitive work programs by Geoscience Australia as well as publicly available exploration results and geoscience literature. Furthermore, the record provides an assessment of issues and unanswered questions and recommends future work directions to meet these unknowns.

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.

The Browse Basin is located offshore on Australia’s North West Shelf and is a proven hydrocarbon province hosting gas with associated condensate. Oil reserves in the area are small with most in-place oil likely the result of hydrocarbon fluids experiencing pressures less than their saturation pressure resulting in dual phase fluids, coupled with secondary alteration processes and gas leakage. This study reviews the distribution, quality and maturity of source rocks and fluid characteristics in the Browse Basin. All publicly-available Total Organic Carbon (TOC) and Rock-Eval pyrolysis data were compiled and quality checked to determine multiple, viable source rock units. Jurassic and Cretaceous source rock distributions and net thickness were studied using integrated seismic and well log lithofacies mapping, combined with organic geochemistry data. Source rock transformation ratio and generation potential were investigated using a regional pseudo-3D petroleum systems model constructed from new seismic interpretations and calibrated using temperature and maturity data from 34 wells. Results show that the Jurassic Plover Formation (J10-J20 supersequences) coals and carbonaceous shales are effective, primarily gas-prone source rocks which may have some liquid potential when the generated gas migrates into shallow reservoirs at reduced pressures. Additional sources of hydrocarbons include shales in the Upper Jurassic lower Vulcan Formation (J40 supersequence), Lower Cretaceous upper Vulcan Formation (K10 supersequence) and Echuca Shoals Formation (K20-K30 supersequences). However, these are likely to have only expelled hydrocarbons locally in areas of optimal organic-richness and maturity. Key uncertainties include TOC and HI variability due to lack of well penetration in the depocentres. The molecular composition of the fluids were compiled and quality checked and used to investigate the relationship between the saturation pressure and condensate-gas ratio (CGR). By combining the bulk properties and molecular and isotopic compositions of the fluids with the geochemical compositions of the source rocks in a petroleum systems model, four Mesozoic petroleum systems have been identified and mapped to help understand the source rock potential and fluid characters for the Browse Basin.

Publicly available geological data in the north Bowen 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 analyses of gas samples from petroleum, coal and coal seam gas boreholes in the basin show traces of natural hydrogen. However, the generation mechanism of the observed natural hydrogen concentration is unknown. Numerous mineral occurrences are found in the basin. Most contain gold, which historically has often been mined. Most occurrences are small, with some exceptions, such as Cracow, Golden Plateau, Kauffman’s Prospect and Miclere gold deposits. The north Bowen Basin has potential for epithermal gold-silver and gold-copper deposits in the deeper formations, but the depth of much of the basin makes exploration and mining difficult and expensive. There is also potential for sandstone-hosted uranium and paleoplacer gold deposits in the upper coal-bearing formations, such as what is seen in the Miclere area. The north Bowen Basin has a significant quantity of coal, with 152 deposits found in the basin, totalling about 47 billion tonnes of black coal. The results of CO2 geological storage assessment of 3 play intervals in the north Bowen Basin suggest there is low storage potential within the basin.

Statements of existing knowledge are compiled for known mineral, coal, hydrocarbon and carbon capture and storage (CCS) resources and reserves in the Adavale Basin. This data guide illustrates the current understanding of the distribution of these key resource types within the Adavale Basin region based on trusted information sources. It provides important contextual information on the Adavale Basin and where additional details on discovered resources can be found. So far, mineral deposits have not been found in the Adavale Basin. There are no coal deposits found in the basin itself, but 6 large coal deposits exist in the overlying basins in the Adavale Basin region. Historically, some small conventional gas resources have been found in the basin. Currently, there are no commercial reserves or available resources identified in the Adavale Basin itself. There are no active or planned carbon capture and storage (CCS) projects in the Adavale basin.
