The greater McArthur Basin of northern Australia is a vast frontier exploration province for basin-hosted resources, both hydrocarbons (oil and natural gas) and metals (critical metals [e.g. rare earth elements, Co], Cu, Pb, Zn and Au). This basin system covers much of northern Australia and may have included much of North China that lay off northern Australia when the basin formed—ca. 1820–1325 Ma. Hydrocarbon and metal deposits in the basin are largely controlled by host sediment composition and ‘redox traps’ related to ancient water chemistry, which, in-turn, are modulated by biological activity, tectonism and relative sea level change. None of these controls are fully understood or constrained throughout the basin.

The Beetaloo Sub-basin is a concealed, composite depocenter and a component of a group of intra-cratonic Paleoproterozoic to Mesoproterozoic sedimentary basins collectively described as the Greater McArthur Basin. The Sub-basin hosts unconventional and conventional petroleum resources, particularly in the uppermost Roper Group where stacked play opportunities include liquids rich shale, dry gas shale and hybrid/ tight gas plays (Côté et al. 2018; Altmann et al., 2020).
Beetaloo次盆地是一个隐伏的复合沉积中心，是克拉通内古元古代至中元古代沉积盆地的组成部分，这些沉积盆地统称为大麦克阿瑟盆地。该子盆地拥有非常规和常规石油资源，特别是在最上层的Roper组，那里的叠合油气藏包括富液页岩、干气页岩和混合/致密气气藏(Côté et al. 2018;Altmann et al.， 2020)。

The Beetaloo Sub-Basin in the Northern Territory is a Proterozoic basin filled predominantly with siliciclastics rocks, the deeper sections only found in sub-crop (Munsen, 2016). The Beetaloo Sub-Basin hosts significant unconventional hydrocarbon resources within three identified shale reservoir intervals of the Mesoproterozoic Velkerri Formation (Close, 2016).

The Centralian Superbasin (CSB) is a ~ 2 million km2 Neoproterozoic to early Palaeozoic (ca. 850−400 Ma) intracratonic depositional system, which stretches across four states (WA, NT, SA and QLD) and is of fundamental scientific and economic significance to Australia. Sedimentary sequences within the CSB, comprising the Amadeus/Warburton, Georgina and Officer Basins, record a critical phase of Earth history, encompassing the Neoproterozoic rise of atmospheric oxygen, major reorganisations in the global carbon cycle and the emergence of the first complex life.

Recent developments in tandem laser ablation-mass spectrometer technology have been shown to be capable of separating parent and daughter isotopes of the same mass online. Consequently, beta decay chronometers can now be applied to the geological archive in situ as opposed to through traditional whole-rock digestions. This new technique provides quicker and cheaper acquisition of geochronological and geochemical data whilst still maintaining a sample’s petrographic context.

Both the petroleum and mineral industries have relied on proven methods when exploring for economic deposits. All methods have their origins in a deep understanding in geological principles, so it’s no surprise that there are many analogous processes employed across both industries. A significant difference is “where” in the earth’s crust the commodity of interest is accumulated and extracted. Economic recovery of any resource drives “how” explorers go about finding the commodity of interest and what tools they employ in their search.

As the world transitions to a low carbon future and global helium consumption grows, the Amadeus Basin is emerging as a prime location for high helium and natural hydrogen gas exploration. With a regionally extensive evaporite seal, and significant hydrogen and helium identified in sub-evaporite gases, the Amadeus Basin has potential to be one of the world’s premier provinces for naturally occurring hydrogen and helium production. Gas compositions from the Mt Kitty 1 well indicate >11% hydrogen and 9% helium (very high concentrations by global standards), with 6% helium also encountered in the Magee 1 well.

The Lucas Outlier was previously interpreted as an outlying component of the Canning Basin that crossed the Western Australian border into the Northern Territory (Hocking, 1994). Recent fieldwork and detrital geochronology (Wingate et al., 2021) now suggest a much older age for the lowest and dominant component of the Lucas Outlier than previously thought, suggesting a closer relationship with the underlying Murraba Basin, a component of the Centralian Superbasin.

The early Permian Patchawarra Formation is one of the principal gas producing intervals of the South Australian Cooper Basin (Government of South Australia., 2022). The gross depositional environment (GDE) for this interval is reported to be dominantly fluvial plain (Strong et al., 2002 and Stephens et al., 2014). However, recent logging and interpretation of 296 m of the Patchawarra Formation from seven wells (Dullingari 39, Fly Lake 2, Halsam 1, Le Chiffre 1, Moomba 194, Pando 1 and Talaq 1), from the South Australian Cooper Basin, indicate the presence of significant lacustrine depositional environments, including shoreface, possible lacustrine turbidites and potential incised valleys, all of which may alter exploration and development strategies.
