Notes on North Australian Craton Solid Geology Maps. Northern Territory-Queensland, 2015-20

This record contains geological notes on solid geology interpretation of 1:250 000 Sheet areas in the Northern Territory and Queensland. There are five layers in the dataset: Pre-Neoproterozoic, Neoproterozoic, Paleozoic, Mesozoic and Cenozoic. Preparation of these layers involved figuratively peeling off successively older rocks and identifying and outlining the rocks thereby revealed. The notes provide comments on the rocks comprising each layer, and explain how the identity of the revealed rocks was arrived at where this is not obvious. The Cenozoic time slice was extracted from the 1:1M scale outcrop geology (Raymond et al., 2012) after removing the surficial deposits and without further interpretation.

Northern Lawn Hill Platform Depth Structure and Isochore Mapping Update

The Paleo-Mesoproterozoic Isa Superbasin is located in northwestern Queensland and is part of the geologically complex and resource rich Mount Isa Province. Over the last five years, the Northern Lawn Hill Platform (NLHP) in the northern part of the Isa Superbasin has become a focus for frontier conventional and unconventional hydrocarbon exploration. Thick and extensive organic-rich shale units in the River and Lawn supersequences are of particular interest for unconventional shale gas exploration following a gas discovery in 2014 from the Lawn Shale at Egilabia-2 DW1. Potential shale gas resources in these stratigraphic intervals include 22.1 Tcf of prospective gas and 0.15 Tcf of contingent (2C) gas resources (Armour Energy, 2014 and 2015). Other conventional and unconventional plays may also occur in overlying stratigraphic units within the Isa Superbasin. However despite the increased interest in the region’s petroleum prospectivity, the data coverage across the Isa Superbasin is sparse and aspects of the regional geological framework remain ambiguous.
This report presents an update to seismic and well interpretation in the Isa Superbasin originally undertaken in the late 1990’s as part of the North Australian Basins Resource Evaluation (NABRE) Project in the NLHP, the area with the greatest concentration of data and petroleum exploration activity. The NABRE Project focussed on developing an integrated structural and stratigraphic framework for the NLHP in the context of understanding and predicting sediment-hosted mineral deposits. However, the project did not produce depth-converted structure or isopach maps, which are required for assessing and mapping conventional and unconventional petroleum plays. Assessments of the area’s resource potential would also benefit by incorporating some key recently acquired data sets and published research with the original NABRE work. The original NABRE work has therefore been updated to include interpretations from new seismic and well data, and to generate depth-converted structure and isopach maps for eight key stratigraphic horizons of interest for petroleum exploration in the NLHP. Major sub-surface structures are also formally defined and named based on the depth-structure maps.
The review of the Isa Superbasin geological framework presented here underpins work on two major federal government initiatives, the Exploring For The Future Program and Geological and Bioregional Assessment Program. Recommendations are included in this report on further value adding work that could supplement these programs to better inform prospectivity assessment.

Rock-Eval pyrolysis data from Waukarlycarly 1, Canning Basin, Australia: Destructive Analysis Report 2020-003

The onshore Canning Basin in Western Australia 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. The four-year program led by Geoscience Australia focusses on the acquisition of new data and information about the potential mineral, energy and groundwater resources concealed beneath the surface in northern Australia and parts of South Australia. As part of this program, significant work has been carried out to deliver new pre-competitive data including new seismic acquisition, drilling of a stratigraphic well and the geochemical analysis of geological samples recovered from exploration wells. 
A regional, 872 km long 2D seismic line (18GA-KB1) acquired in 2018 by Geoscience Australia (GA) and the Geological Survey of Western Australia (GSWA), images the Kidson Sub-basin of the Canning Basin. In order to provide a test of geological interpretations made from the Kidson seismic survey, a deep stratigraphic well, Waukarlycarly 1, was drilled in 2019 in partnership between Geoscience Australia (GA) and the Geological Survey of Western Australia (GSWA) in the South West Canning Basin.
The Waukarlycarly 1 stratigraphic well was drilled in the Waukarlycarly Embayment, 67 km west of Telfer and provides stratigraphic control for the geology imaged by the Kidson seismic line (Figure 1). The well was drilled to a total drillers depth (TD) of 2680.53 mRT and penetrated a thin Cenozoic cover overlying a Permo-Carboniferous fluvial clastic succession that includes glacial diamictite. These siliciclastics unconformably overlie an extremely thick (&gt;1730 m) interpreted Devonian to Ordovician succession before terminating in low-grade metasediments of presumed Neoproterozoic age. Log characterisation, core analysis, geochronology, petrographic and palaeontological studies have been carried out to characterise the lithology, age and depositional environment of these sediments. 
As part of this comprehensive analytical program, TOC and Rock-Eval pyrolysis analyses were undertaken by Geoscience Australia on selected rock samples to establish their hydrocarbon-generating potential and thermal maturity.

Levelled surface sediment geochemistry data for the North Australian Craton

Australia has a significant number of surface sediment geochemical surveys that have been undertaken by industry and government over the past 50 years. These surveys represent a vast investment and have up to now only been able to be used in isolation, independently from one another. The key to maximising the full potential of these data and the information they provide for mineral exploration, environmental management and agricultural purposes is using all the surveys together, seamlessly. These disparate geochemical surveys not only sampled various landscape elements and analysed a range of size fractions, but also used multiple analytical techniques, instrument types and laboratories. The geochemical data from these surveys require levelling to eliminate, as much as possible, non-geological variation. Using a variety of methodologies, including reanalysis of both international standards and small subsets of samples from previous surveys, we have created a seamless surface geochemical map for northern Australia, from nine surveys with 15,605 samples. We tested our approach using two surveys from the southern Thomson Orogen, which demonstrated the successful removal of inter-laboratory and other analytical variation. Creation of the new combined and levelled northern Australian dataset paves the way for the application of statistical and data analytics techniques, such as principal component analysis and machine learning, thereby maximising the value of these legacy data holdings. The methodology documented here can be applied to additional geochemical datasets as they become available.

Well log data analysis and interpretation on the pre-Carboniferous succession in Waukarlycarly 1, Canning Basin, Western Australia

Waukarlycarly 1 is a stratigraphic well drilled in the southern part of the Canning Basin’s Waukarlycarly Embayment under Geoscience Australia’s Exploring for the Future program in collaboration with the Geological Survey of Western Australia to provide stratigraphic data for this poorly understood tectonic component. The well intersects a thin Cenozoic section, overlying Permian–Carboniferous fluvial clastics and glacial diamictites, with a thick pre-Carboniferous succession (855–2585 mRT) unconformably overlying the Neoproterozoic metasediments. Three informal siliciclastic intervals were defined based on the data from core lithology, well logs, fluid inclusions, chemical and mineral compositions; an Upper Sandstone (855–1348.1 mRT), a Middle Interval (1348.1–2443.4 mRT) and a Lower Sandstone (2443.4 –2585 mRT). The Middle Interval was further divided into six internal zones. 
Conventional methods were applied to interpret effective porosity, water saturation and elastic properties (Poisson’s ratio and Young’s modulus). Artificial neural network technology was employed on well logs to interpret the total organic carbon (TOC) content, pyrolysis products from the cracking of organic matter (S2), permeability, and mineral compositions. In the Upper Sandstone, average sandstone porosity and permeability are 17.9% and 464.5 mD and, 6.75 % and 10 mD in the Lower Sandstone. The Middle Interval claystone has an average porosity and permeability of 4.17 % and 0.006 mD, and average TOC content and S2 of 0.17 wt% and 0.047 mg HC/g rock with maximum values of 0.66 wt% and 0.46 mg HC/g rock. Average Poisson’s ratio and Young’s modulus of the claystone are 0.154 and 9.81 GPa.
Correlations of mineral compositions, petrophysical, geomechanical and geochemical properties of the Middle Interval have been conducted. Young’s modulus and Poisson’s ratio are well correlated with the contents of key minerals, including Quartz, carbonates and TotalClay. Although TOC content is low at Waukarlycarly 1, hydrocarbon generation and migration have occurred elsewhere in the Waukarlycarly Embayment. The helium response just above the Neoproterozoic basement in the FIS profile is not associated with the hydrocarbon responses implying that these fluids have different sources.
