The Role of Deep Seismic Reflection Data In Understanding the Architecture of Australia's Onshore Sedimentary Basins

The Onshore Energy Security Program, funded by the Australian Government, Geoscience Australia has acquired deep seismic reflection data across several frontier sedimentary basins to stimulate interest in petroleum exploration in onshore Australia. Detailed interpretation of deep seismic reflection profiles from four onshore basins, focusing on overall basin geometry and internal sequence stratigraphy will be presented here, with the aim of assessing the petroleum potential of the basins. 
At the Southern end of the exposed part of the Mt Isa Province, northwest Queensland, a deep seismic line (06GA-M6) crosses the Burke River Structural Zone of the Georgina Basin. The basin here is &gt;50 km wide, with a half graben geometry, and bound in the west by a rift border fault. 
The Millungera Basin in northwest Queensland is completely covered by the thin Eromanga basin and was unknown prior to being detected on two seismic lines (06GA-M4 and 06GA-M5) acquired in 2006. Following this, seismic line 07GA-IG1 imaged a 65 km wide section of the basin. The geometry of internal stratigraphic sequences and post-depositional thrust margin indicate that the original succession was much thicker than preserved today. 
The Yathong Trough in the southeast part of the Darling Basin in NSW has been imaged in seismic line 08GA-RS2 and interpreted in detail using sequence stratigraphic principles, with several sequences being mapped. The upper part of this basin contains Devonian sediments, with potential source rocks at depth.

L040 Surat Basin seismic reflection and refraction survey, QLD, 1960

Reflection and refraction seismic work was done in 1960 to complete a reconnaissance survey which was commenced in 1959 across the northern part of the Surat Basin. A reconnaissance line now extends in an easterly direction from 30 miles west of Surat to Jondaryan, and this line is also tied to the geologically well-known Roma area. Two good marker horizons have been established in the seismic work - one a strong reflector and the other a refractor in which the velocity averages 19,000 ft/sec and which may represent basement. A deep trough of sediments, possibly 20,000 ft thick at Meandarra, exists between Surat and Tara, and there is a large uplift west of Tara. The eastern margin of this large trough is 12 miles east of Tara, but sediments about 4000 ft thick probably continue to the east, at least as far as Jondaryan.

Data integration for greenfields exploration: an example from the East Tennant region, Northern Territory

It is increasingly recognised that, to maintain a sustainable pipeline of mineral resources in Australia, future discoveries will need to be made in areas obscured by more recent cover sequences. A major challenge to mineral exploration in covered frontiers is identifying new prospective fairways, and understanding and mapping important metallogenic processes at a range of scales to enable more effective targeting of exploration. Here, we present evidence for a completely buried corridor of interpreted high prospectivity—the East Tennant region—based on synthesis and integration of a diverse range of geoscientific datasets. Key indicators of the region’s potential include lithospheric-scale architecture, elevated electrical conductivity in the crust and mantle, and modelled and demonstrated hydrothermal alteration in the near surface. Multiscale geophysical surveys show evidence for crustal-scale fluid flow along major structures, connecting the mantle with the surface. Although few geological constraints exist in this region, examination of legacy drillcore and geochronology results demonstrates a similar history to rocks known to host mineralisation across the North Australian Craton. These results provide tantalising indications that the under-explored East Tennant region has significant potential to host major mineral systems.

GSQ Bowen Surat South magnetic grid geodetic

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This GSQ Bowen Surat South magnetic grid geodetic has a cell size of 0.00083 degrees (approximately 87m). The units are in nanoTesla (or nT).

Exploring for the Future: Molecular and Isotopic Compositions of Natural Gases from Canunda 2 and Ralgnal 1, Cooper Basin, Australia

The Australian Government’s $225 million Exploring for the Future (EFTF) program is committed to supporting a strong economy, resilient society and sustainable environment for the benefit of Australians (https://www.ga.gov.au/eftf). At its heart, the program is about stimulating industry now to ensure a sustainable, long-term future for Australia through an improved understanding of the nation’s minerals, energy and groundwater resource potential. By gathering and analysing geological and geophysical data and making the results publicly available, the program supports regional development and informed decision making across Australia, resulting in jobs and growth. The Energy component of this program is designed to produce pre-competitive information to assist with the evaluation of the hydrocarbon resource potential of onshore basins and attract exploration investment to Australia.
As part of the EFTF Natural Hydrogen module, molecular and isotopic analyses were undertaken by Geoscience Australia on natural gas samples from the wells Canunda 2 and Ralgnal 1 from the southwestern margin of the Patchawarra Trough in the Cooper Basin, with the raw data from these analyses being released in this report. Some data from these wells were included in the nationwide studies of helium and hydrogen, as published by Boreham et al. (2018; 2021), and build on previous studies that document the composition of Australian natural gases (Boreham et al., 2001). These data are available through the Geoscience Australia portal at https://portal.ga.gov.au/
