<div>Geoscience Australia’s Onshore Basin Inventories project delivers a single point of reference and creates a standardised national basin inventory that provides a whole-of-basin catalogue of geology, petroleum systems, exploration status and data coverage of hydrocarbon-prone onshore Australian sedimentary basins. In addition to summarising the current state of knowledge within each basin, the onshore basin inventory reports identify critical science questions and key exploration uncertainties that may help inform future work program planning and decision making for both government and industry. Volume 1 of the inventory covers the McArthur, South Nicholson, Georgina, Wiso, Amadeus, Warburton, Cooper and Galilee basins and Volume 2 expands this list to include the Officer, Perth and onshore Canning basins. Under Geoscience Australia’s Exploring for the Future (EFTF) program, several new onshore basin inventory reports are being delivered. Upcoming releases include the Adavale Basin of southern Queensland, and a compilation report addressing Australia’s poorly understood Mesoproterozoic basins. These are supported by value-add products that address identified data gaps and evolve regional understanding of basin evolution and prospectivity, including petroleum systems modelling, seismic reprocessing and regional geochemical studies. The Onshore Basin Inventories project continues to provide scientific and strategic direction for pre-competitive data acquisition under the EFTF work program, guiding program planning and shaping post-acquisition analysis programs.</div>

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.
