Impacts of Pre‐Existing Structural Fabrics on Fault Growth and Evolution During Multi‐Phase Rifting: Case Study From the Central Browse Basin, North West Shelf of Australia Open
In multi‐phase rifts, pre‐existing structural fabrics that are formed during earlier rifting stages can influence fault growth during later deformation. Successive extensional episodes cause pre‐existing faults to reactivate, leading to th…
The Derim Derim Dolerite, greater McArthur Basin, Australia: Using subsurface data to characterise a mesoproterozoic magma plumbing system Open
Open Access via the Elsevier Agreement. This work was carried out during a research visit to the University of Adelaide, and forms part of a PhD study undertaken as part of the Centre of Doctoral Training (CDT) in Geoscience and the Low Ca…
Key considerations for evaluating Underground Hydrogen Storage (UHS) potential in five contrasting Australian basins Open
Hydrogen gas can provide baseload energy as society decarbonizes through the energy transition. Underground Hydrogen Storage (UHS) will be secure, convenient and scalable to accommodate excess hydrogen production or compensate temporary sh…
The magma plumbing system of the Northern Carnarvon Basin, offshore Australia: multiscale controls on basin-wide magma emplacement, and implications for petroleum exploration Open
The Northern Carnarvon Basin (NCB) located on Australia's North West Shelf hosts an extensive (∼40 000 km 2 ) intrusive igneous complex related to Mesozoic rifting and break-up. Using an extensive suite of modern 3D seismic reflection surv…
Hydrogen Gas Storage Prospects in the offshore Gippsland Basin Open
The Gippsland Basin has been a prolific petroleum producing basin that was recently thought to be the ideal end point for a local Carbon Capture and Storage (CCS) value chain. Previous studies have demonstrated sufficient sealing capacity …
Tectono-magmatic evolution of the Browse Basin, North West Shelf: Insights for hydrocarbon exploration in igneous provinces Open
Continental margins often undergo complex geological histories, including multiple rift phases, igneous activity, and drastic changes in their sedimentary environments. To succeed in hydrocarbon exploration in such areas, it is necessary t…
2D Seismic Analysis for unraveling the structural and tectonostratigraphic evolution of the Gippsland basin, southern Australia. Open
The Gippsland basin is part of the Australian southern margin rift system. It is a world class oil and gas producing province located about 200 km east of the city of Melbourne, and covers about 46 000 km2 onshore and offshore. The offshor…
Seismic, petrophysical and petrological constraints on the alteration of igneous rocks in the Northern Carnarvon Basin, Western Australia: implications for petroleum exploration and drilling operations Open
The Northern Carnarvon Basin (NCB) hosts an extensive record of Jurassic–Cretaceous rift-related igneous activity, manifested by a >45 000 km2 intrusive complex and series of volcanic centres constrained by seismic mapping. However, there …
How do detachment properties influence the kinematics of normal growth faults? Insights from 3D seismic reflection data from the Ceduna sub-basin. Open
The growth of gravity-driven normal faults exerts a critical control on multiple elements and processes of the petroleum system. However, there is still a poor understanding of the interactions between the properties of detachment layers a…
Recognition of igneous rocks encountered in wells in the Carnarvon Basin, Western Australia: Implications for drilling and petroleum systems. Open
The Carnarvon Basin formed during the separation of Greater India and Australia in the Mesozoic. Rifting was associated with the generation of large volumes of melt (possibly related to a hotspot beneath the Cape Range Fracture Zone), whic…
Storing CO2 in buried volcanoes Open
Australia contains rich natural gas resources, but many of Australia’s currently producing and undeveloped gas fields contain relatively high CO2 contents; if not captured and stored, the venting of co-produced CO2 could hinder efforts to …
Cenozoic structural evolution of the Mount Lofty Ranges and Flinders Ranges, South Australia, constrained by analysis of deformation bands Open
The presence of deformation bands in Upper Cretaceous–Pleistocene sediments of the St Vincent and Lake Eyre basins, South Australia supports the occurrence of intraplate normal and reverse faulting in this region throughout the Cenozoic. C…
Quantified Detection of Carbonate Cementation in Sandstones using Standard Wireline Log Data Open
SummaryCarbonate cemented zones were identified within the lower Paaratte Formation of the eastern Otway Basin, Victoria, in southeastern Australia. A wireline log model trained on these zones can predict carbonate cementation within Late …
The spatial distribution of igneous intrusions in the Exmouth Plateau and Exmouth Sub Basin, North West Shelf, Western Australia. Open
SummaryThe North West Shelf of Australia is a volcanic rifted margin. Jurassic-Cretaceous breakup of Gondwana resulted in the intrusion of significant volumes of igneous material into sediments of the Northern Carnarvon Basin. The last maj…
Nature and origin of Jurassic volcanism in the Eromanga Basin Open
SummaryThe Cooper and Eromanga Basins of South Australia and Queensland are the largest onshore hydrocarbon producing region in Australia. Igneous rocks have been documented infrequently within end of well reports over the past 34 years, w…
Predicting and Detecting Carbonate Cemented Zones Within Latrobe Group Reservoirs of the Gippsland Basin Open
A wireline log model predicts carbonate cemented zones within Late Cretaceous to Paleocene reservoir sandstones of the Latrobe Group, Gippsland Basin. Predictions match published evidence. These sandstones were once heavily cemented prior …
Linear Trends of Paleo-Pockmarks and Fluid Flow Pipes in the Jurassic and Triassic Sediments of Offshore Northwest Australia Open
This study records 315 paleo-pockmarks with associated focused fluid flow pipes within the Jurassic and Triassic sediments over three study areas on the Exmouth Plateau, offshore Northwest Australia. Paleo-pockmarks are identified along a …
Control on Pleistocene shelf drainage by post-Eocene stratigraphy of the Gippsland Basin Open
The Jemmys Point Formation - uppermost member of the cool-water carbonate Seaspray Group - records a terrestrial drainage system that traversed the now submerged continental shelf of the Gippsland Basin during the latest ice age. A partial…
