This dataset represents the results of the assessment of the potential for uranium and geothermal energy systems in the southern Northern Territory. Four uranium systems were targeted: 1) sandstone-hosted, 2) uranium-rich iron oxide-copper-gold, 3) unconformity-related, and 4) magmatic-related. These were assessed for using a 2D, GIS-based approach, and utilised a mineral systems framework. In addition to the uranium systems investigated, the potential for hot rock and hot sedimentary aquifer geothermal systems was also assessed. Only the results of the hot rock geothermal assessment are presented here, since the assessment for hot sedimentary aquifer geothermal systems is more qualitative in nature. The assessment for hot rock geothermal systems was undertaken in a 3D environment, with temperatures at depth predicted using the 3D GeoModeller software package.

The Habanero Enhanced Geothermal System (EGS) in central Australia has been under development since 2002, with several deep (more than 4000 m) wells drilled to date into the high-heat-producing granites of the Big Lake Suite. Multiple hydraulic stimulations have been performed to improve the existing fracture permeability in the granite. Stimulation of the newly-drilled Habanero-4 well (H-4) was completed in late 2012, and micro-seismic data indicated an increase in total stimulated reservoir area to approximately 4 km². Two well doublets have been tested, initially between Habanero-1 (H-1) and Habanero-3 (H-3), and more recently, between H-1 and H-4. Both doublets effectively operated as closed systems, and excluding short-term flow tests, all production fluids were re-injected into the reservoir at depth. Two inter-well tracer tests have been conducted: the first in 2008, and the most recent one in June 2013, which involved injecting 100 kg of 2,6 naphthalene-disulfonate (NDS) into H-1 to evaluate the hydraulic characteristics of the newly-created H-1/H-4 doublet. After correcting for flow hiatuses and non-steady-state flow conditions, tracer breakthrough in H-4 was observed after 6 days (compared to ~4 days for the previous H-1/H-3 doublet), with peak breakthrough occurring after 17 days. Extrapolation of the breakthrough curve to late time indicates that approximately 60% of the tracer mass would eventually be recovered (vs. approximately 80% for the 2008 H-1/H-3 tracer test). This suggests that a large proportion of the tracer may lie trapped in the opposite end of the reservoir from H-4 and/or may have been lost to the far field. The calculated inter-well swept pore volume is approximately 31,000 m³, which is larger than that calculated for the H-1/H-3 doublet (~20,000 m³). A simple 2D TOUGH2 tracer model, with model geometry constructed based on the current conceptual understanding of the Habanero EGS system, demonstrates good agreement with the measured tracer returns in terms of timing of breakthrough in H-4, and observed tracer dispersion in the tail of the breakthrough curve.

<div><strong>Output Type: </strong>Exploring for the Future Extended Abstract</div><div><br></div><div><strong>Short Abstract:</strong> GeoInsight (https://geoinsight.ga.gov.au) is a new digital geological information platform for non-geoscientists, developed through an 18-month pilot project as part of Geoscience Australia’s <em>Exploring for the Future</em> Program (2016-2024). The aim of this pilot was to develop a new approach to digitally communicating geological information to non-geoscience professionals on a region-by-region basis. GeoInsight was developed using a human-centred design approach through which users expressed a need for a simple and fast, plain-language experience which provided basic information and pathways for further research. GeoInsight’s vision is for an accessible experience that curates information and data from across the Geoscience Australia ecosystem, helping users make decisions and refine their research approach, quickly, and confidently. GeoInsight has successfully brought together information from over 20 sources about energy, minerals, and groundwater on a region-by-region basis drawing on information from across Geoscience Australia and external partner organisations. The platform and data package developed during the pilot form the foundations for further refinement and development based on user needs.</div><div><br></div><div><strong>Citation: </strong>Waltenberg, K., Wainman, C.C., Hawkins, S.G., Oborski, E.M., Sen, A., Knepprath, N.E., Holzschuh, J., Sunketa, A., Farmakis, B., Edmonson, S., Czarnota, U., Sedgmen, A. & Seedhouse, M., 2024.

<div>The “Australia’s Future Energy Resources” (AFER) project, funded under the Government’s “Exploring for the Future” (EFTF) program has been completed. The project’s four modules have evaluated a mixture of energy resource commodities, including natural gas, hydrogen, subsurface storage opportunities for carbon dioxide and hydrogen. They are complimented by several targeted basin inventories which outline the current geological knowledge of energy resources in underexplored, data-poor regions. Several publicly available data sets have been generated and published under the AFER project, including 3,750 line-km of reprocessed 2D seismic data, acquired in the Pedirka and western Eromanga basins, of which key lines have been interpreted and integrated with geological and petrophysical well log data. Relative prospectivity maps have been produced for five energy resource commodities from 14 play intervals to show the qualitative variability in prospectivity of these resources, including quantitative resource assessments where warranted. Results from the AFER project have helped to identify and geologically characterise the required energy resource commodities to accelerate Australia’s path to net zero emissions.</div> Presented at the Australian Energy Producers (AEP) Conference & Exhibition (https://energyproducersconference.au/conference/)

<div>GeoInsight was an 18-month pilot project developed in the latter part of Geoscience Australia’s Exploring for the Future Program (2016–2024). The aim of this pilot was to develop a new approach to communicating geological information to non-technical audiences, that is, non-geoscience professionals. The pilot was developed using a human-centred design approach in which user needs were forefront considerations. Interviews and testing found that users wanted a simple and fast, plain-language experience which provided basic information and provided pathways for further research. GeoInsight’s vision is to be an accessible experience that curates information and data from across Geoscience Australia, helping users make decisions and refine their research approach, quickly and confidently.</div><div><br></div><div>In the first iteration of GeoInsight, selected products for energy, minerals, water, and complementary information from Geoscience Australia’s Data Discovery Portal and Data and Publications Catalogue were examined to (1) gauge the relevance of the information they contain for non-geoscientists and, (2) determine how best to deliver this information for effective use by non-technical audiences.</div><div><br></div><div>This Record documents the technical details of the methods used for summarising energy commodities for GeoInsight. These methods were devised to convey current production and future production/extraction potential quickly and efficiently for regions across the Australian continent. Evaluated energy commodities include oil and gas, hydrogen and geological hydrogen storage, uranium and thorium, coal (black and brown), geothermal energy, and renewable energy. Carbon storage, a decarbonisation enabler, was also addressed under the energy theme.</div><div><br></div><div>This document contains two sections:</div><div><strong>Production Summary:</strong> To showcase where energy resources are being produced in different regions of Australia. The source datasets provide a snapshot of energy production activities at the time of publication. </div><div><strong>Potential Summary:</strong> To highlight, at first glance, the likelihood that future energy production and decarbonisation initiatives may occur in different regions of Australia. The source datasets provide a snapshot of future energy potential at the time of publication.</div><div><br></div><div>Any updates to the methodology used in GeoInsight will be accompanied by updates to this document, including a change log.</div><div>Geoscience Australia’s Exploring for the Future program provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources. By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia’s geology and resource potential. This leads to a strong economy, resilient society and sustainable environment for the benefit of all Australians. This includes supporting Australia’s transition to net zero emissions, strong, sustainable resources and agriculture sectors, and economic opportunities and social benefits for Australia’s regional and remote communities. The Exploring for the Future program, which commenced in 2016, is an eight year, $225m investment by the Australian Government.</div><div><br></div>

Poster describing synthetic thermal modelling and its application to geothermal exploration in Australia
-
Currently it is difficult to assess the quality of Australian geothermal exploration targets, particularly for those with differing amounts of geological data. To rectify this, Geoscience Australia is developing a tool for evaluating geothermal potential across the continent and for identifying areas that warrant additional investigation. An important first step in the development of this tool is synthetic thermal modelling. Synthetic modelling has been used to perform a sensitivity analysis, determine the importance of different geothermal parameters and the values necessary to produce specific temperatures at depth. The results of this work are presented in this abastract.
