The Officer-Musgrave project investigates the groundwater and energy resource potential of the Officer Basin and neighbouring Musgrave Province near the junction of South Australia, Western Australia and the Northern Territory (Figure 1). Groundwater investigations focus on the Musgrave Province and overlying Officer Basin to identify potential palaeovalley groundwater resources, to support geological framework data acquisition and geochemistry. Groundwater systems in remote regions, such as the Officer-Musgrave region, are poorly understood due to sparse geoscientific data and few detailed scientific inestigations having been undertaken. Characterising the distribution and quality of groundwater resources, will lead to a better understanding of the groundwater resources for community supply and economic development opportunities. The energy resource component of the project focuses on the analysis of existing legacy datasets, including seismic and well data, in the Officer Basin and acquisition of key new precompetitive data. These activities will improve understanding of regional resource potential, with the aim of stimulating industry exploration investment in the medium-term, ultimately leading to new discoveries and wealth creation. This work builds directly on work completed in the first phase of the Exploring for the Future program, which enhanced our understanding of Centralian Superbasin stratigraphy (Khider et al., 2021; Bradshaw et al., 2021).

Summary of last 12 months activity in Acreage Release Area.

High voltage transmission towers are key linear assets that supply electricity to communities and key industries and are constantly exposed to wind effects where they traverse steep topography or open terrain. Lattice type high voltage transmission towers are highly optimised structures to minimise cost and reserve strength at design wind speeds (Albermani and Kitipornchai, 2003). The structures are tested under static loading conditions for specified load cases at the design stage. However, the interconnected nature of the lattice towers and conductors present a complex response under dynamic wind loading in service (Fujimura, el.al., 2007). The transmission tower's survival under severe wind and additional load transfer due to collapse of its neighbours is difficult to assess through modelling. Furthermore, the lack of data in the industry doesn't allow for a probabilistic analysis based on history (Abdallah, et.al., 2008). Hence, there is a need for developing an alternative methodology for analysing transmission tower collapse and survival of transmission lines subjected to cyclonic winds utilising design information, limited field data and industry expertise.

This short video summarises the value of Geoscience Australia's work to the discovery, development and export of Australia's mineral and energy commodities. The video is from a series of six films produced to communicate Geoscience Australia's value to the nation.

The South Nicholson region of northwest Queensland and the Northern Territory is the focus of a regional hydrocarbon prospectivity assessment being undertaken by the Exploring for the Future (EFTF) program, an Australian Government initiative dedicated to increasing investment in resource exploration in northern Australia. This data release provides data from new digital photography, X-ray Computerised Tomography (XCT) scanning, unconfined compressive strength (UCS) testing and laboratory ultrasonic testing for 14 samples from stratigraphic and exploration wells drilled into the South Nicholson Basin and Lawn Hill Platform in the South Nicholson region described in Jarrett et al (2020). These samples were analysed at CSIRO Geomechanics and Geophysics Laboratory in Perth during May and June 2020.

This GIS package contains interpreted boundaries and thalwegs (valley bottoms) of Cenozoic palaeovalley systems derived from the Frome AEM Survey dataset. Palaeovalley boundaries are by Adrian Fabris, DMITRE, and include interpreted Eyre Formation sediments only. Palaeovalley thalwegs are by Ian Roach, GA, and include interpreted Eyre Formation and Namba Formation sediments. This dataset supports the Frome AEM Survey interpretation record, GA Record 2012/40-Geological Survey of South Australia Report Book 2012/00003.

Poster describing synthetic thermal modelling and its application to geothermal exploration in Australia

Precompetitive AEM data and associated scientific analysis assists exploration under cover by reducing risk, stimulating investment and promoting exploration for commodities. In recent years, Geoscience Australia has flown three regional Airborne Electromagnetic (AEM) surveys covering three percent of Australia. Data and associated interpretations from regional surveys in the Paterson, Pine Creek and Lake Frome regions have led to tenement take up, stimulated exploration for a number of commodities and have given rise to many Eureka moments. This presentation will outline significant results from the use of Geoscience Australia AEM data and interpretations, results that have been announced by industry via the Australian Stock Exchange and other publications.
