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. The Paleo to Mesoproterozoic Birrindudu Basin is an underexplored frontier basin located in northwestern Northern Territory and northeastern Western Australia. The Birrindudu Basin is a region of focus for the second phase of the EFTF program (2020–2024) as it contains strata of similar age to the prospective McArthur Basin, South Nicholson region and Mount Isa Province, but remains comparatively poorly understood. Geoscience Australia have undertaken (via the service provider, FIT, Schlumberger) stratigraphic reconstructions of bulk volatile chemistry from fluid inclusions from an mineral exploration drillhole LBD2, Birrindudu Basin, located in the northwest Northern Territory This ecat record releases the final report and raw data files (*.LAS) by FIT Schlumberger. Company reference number FI230005a.

Exploring for the Future (EFTF) is an Australian Government program led by Geoscience Australia (GA), in partnership with state and Northern Territory governments. The EFTF program (2016-2024) aims to drive industry investment in resource exploration in frontier regions of onshore Australia by providing new precompetitive data and information about their energy, mineral and groundwater resource potential. Under the EFTF program, the Onshore Energy Project undertook a study of petroleum prospectivity of the onshore Officer Basin in South Australia and Western Australia. Birksgate 1 well in South Australia was selected based on the occurrence of gas and oil shows reported in the well completion report. Sampling of cuttings and cores was done at Geoscience Australia's Petroleum Data Repository in Canberra. Geoscience Australia commissioned a fluid inclusion stratigraphy (FIS) study on the downhole samples. Here, volatile components ostensibly trapped with fluid inclusions are released and analysed revealing the level of exposure of the well section to migrating fluids. Integration of thin section (TS) preparations reveal to extent of gas and fluid trapping within fluid inclusions while microthemometry (MT) gives an estimation of fluid inclusion trapping temperature. For Birksgate 1, FIS analysis was performed on 414 cuttings and 33 cores between 150 feet and 6161 feet base depth, together with 14 samples prepared for TS and 3 samples for MT. To support this study, lithostratigraphic tops were compiled by Geoscience Australia. The results of the study are found in the accompanying documents.

This report presents groundwater level information collected during Geoscience Australia’s Musgrave Palaeovalley Project. The Musgrave Palaeovalley Project was conducted as part of Exploring for the Future (EFTF), an Australian Government funded geoscience data and information acquisition program. The eight-year, $225 million program aims to deliver new geoscience data and knowledge to inform decision-making by government, community, and industry on the sustainable development of Australia's mineral, energy, and groundwater resources.</div><div>Groundwater level data was collected during two hydrogeochemical surveys undertaken in March and May 2023 based around the remote communities of Warburton, Kaltukatjara, Wanarn, Blackstone and Jameson in Western Australia and the Northern Territory. Sixteen bores were measured for their groundwater levels. The results are contained herein and within the attached CSV file.

<div>This report details results and methodology from two hydrochemistry sampling programs performed as part of Geoscience Australia’s Musgrave Palaeovalley Project. The Musgrave Palaeovalley Project is a data acquisition and scientific investigation program based around the central west of Australia. It is aimed at investigating groundwater processes and resources within the Cenozoic fill and palaeovalleys of the region. This project, and many others, have been performed as part of the Exploring for the Future (EFTF) program, an eight-year, $225 million Australian Government funded geoscience data and precompetitive information acquisition program.</div><div>Data released here is from 18 bores sampled for groundwater and tested for a range of analytes including field parameters, major and minor elements, isotopes and trace gases. The sampling methods, quality assurance/quality control procedures, analytical methods and results are included in this report.</div>

<div>The Birrindudu Basin is a region of focus for the second phase of the Geoscience Australia’s Exploring for the Future (EFTF) program (2020–2024). The Paleo to Mesoproterozoic Birrindudu Basin is an underexplored frontier basin located in northwestern Northern Territory and northeastern Western Australia. Interpretation of industry seismic data indicates it contains strata of similar age to the prospective McArthur Basin, South Nicholson region and Mount Isa Province, but remains comparatively poorly understood. Furthermore, much of the age of the stratigraphy of the Birrindudu Basin, particularly the younger stratigraphic units, and regional correlations to the greater McArthur Basin remains provisional and speculative.&nbsp;</div><div><br></div><div>This report presents data from Rock-Eval pyrolysis analyses undertaken by Geoscience Australia on selected rock samples to establish their total organic carbon content, hydrocarbon-generating potential and thermal maturity from 178 drill core samples from six drill holes intersecting units of the Birrindudu Basin including: 99VRNTGSDD1, 99VRNTGSDD2, WLMB001B, LBD2, LMDH4, and ANT003. </div><div><br></div>

<div>This report presents new data from X-ray Computerised Tomography (XCT) scanning, gas porosity and permeability testing, and grain density measurements of 79 of 82 samples from the Birrindudu and McArthur basins. Three plugs could not be recovered from the whole core section. Plugs were taken from depths of interest from drill holes Manbulloo S1, Hidden Valley S2, Broughton 1, ANT003, 99VRNTGSDD1, 99VRNTGSDD2, Lamont Pass 3 and WLMB001B.</div><div><br></div><div>These tests were performed in 2023 by CSIRO in Perth.

Geoscience Australia (in collaboration with the Northern Territory Geological Survey) acquired around 700 line-kms of deep crustal reflection seismic data across northwest Northern Territory encompassing not only the frontier Birrindudu Basin but adjacent highly prospective regions, such as the Tanami. This ecat record releases the final survey route shapefiles, noting that some segments were not acquired due to site access restrictions. Seismic field data will be published in the near future release following completion of in-house QA/QC protocols

<div>This report presents seal capacity results of nine samples from the Birrindudu and McArthur basins, Northern Territory. Plugs were taken from depths of interest from drill holes Manbulloo S1, Broughton 1, Lamont Pass 3, 99VRNTGSDD1 and WLMB001B. These plugs were analysed via mercury injection capillary pressure testing. This work was conducted by CSIRO under contract to GA as part of the Exploring for the Future program (Officer–Musgrave–Birrindudu Module).</div>
