Abstract
<div>Geoscience Australia’s Exploring for the Future (EFTF) 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.</div><div><br></div><div>The Stansbury Basin is a relatively underexplored basin in southern South Australia. Stansbury West 1 was drilled on the east coast of Yorke Peninsula to test the basal Permian sands and Paleozoic carbonate known to contain traces of hydrocarbon gas and residual oil. The well encountered no significant hydrocarbons and was abandoned as dry. A known occurrence of hydrogen-rich natural gas was discovered nearly a century ago in a well to the north of Stansbury West 1. Also potential hydrogen gas enrichment in the near-surface in the surrounds of the Stansbury West 1 drillhole has been proposed using satellite imagery and land surface features.</div><div><br></div><div>The study of natural hydrogen gas occurrences is a focus for the second phase of the EFTF program (2020–2024) and the fluid inclusion stratigraphy (FIS) technique of Fluid Inclusion Technology (Schlumberger) provides a convenient method to measure the well's complete downhole section for both hydrocarbon non-hydrocarbon gases that have been geologically trapped in fluid inclusions and then mechanically released in the laboratory.</div><div><br></div><div>Geoscience Australia have undertaken (via the service provider, FIT Schlumberger) stratigraphic reconstructions of bulk volatile chemistry from fluid inclusions from the drillhole Stansbury West 1, Stansbury Basin. FIS analysis was performed on 270 cuttings and core samples from 15.24 to 1743.53 metres, including 4.9 metres of Archean gneiss and granitic basement at the base of the drillhole.</div><div><br></div><div>This ecat record releases the final report containing the results of fluid inclusion stratigraphy and thin section analyses, raw data files (*.LAS) and rock descriptions by FIT Schlumberger (Company reference number FI220025a).</div>
