Subsidence and thermal history modelling:new insights into hydrocarbon expulsion from multiple petroleum systems in the Browse Basin

Subsidence and thermal history analysis of 31wells and 25 depocentre sites has been undertaken to examine the generation and expulsion history of Jurassic and Early Cretaceous petroleum systems in the Browse Basin. The models incorporate new palaeo-bathymetric estimates of the deepwater post-Valanginian to Early Tertiary succession based on seismic geometries and detailed benthic foraminiferal data, as well as new kerogen kinetic data for multiple potential source units.
The models suggest multiple effective source units for gas expulsion in the basin, whereas effective oil charge is largely restricted to the Heywood Graben in the northeast, and the rift section in the deepwater Serringapatam Sub-basin. Significant quantities of oil are modelled to have been expelled from Jurassic sediments (Plover and Lower Vulcan formations) in the Heywood Graben during the Tertiary and Late Tertiary, respectively. These charges are likely to have sourced the thick palaeo-oil columns interpreted at Heywood-1 and Crux-1.
Modelled oil expulsion in the deepwater Seringapatam Sub-basin is highly sensitive to the organic richness and quality of interpreted Jurassic rift sediments. Provided these units contain good quality source rocks comparable to those within Jurassic rifts elsewhere on the North West Shelf, then significant quantities of oil and gas are modelled to have been expelled from this graben during the Late Tertiary. Evidence of such an oil charge may be provided by thin zones of elevated GOI data in Jurassic reservoirs at North Scott Reef-1, Scott Reef-2A and Brecknock-1, all located on a major anticlinal trend inboard of the Seringapatam graben.
Regional models of the recently identified, oil-prone, Early Cretaceous (Echuca Shoals Formation) petroleum system suggest that these rocks have not expelled significant volumes of oil. However, organic-rich sediments within this succession occur as thin transgressive sheets deposited in response to fluctuating sea level on a gently inclined ramp margin, and thus higher-resolution sequence stratigraphic models are required to more accurately assess their local expulsion history. Local effective oil charge from these sources is confirmed by the Cornea, Gwydion-1 and Caswell-2 accumulations.
The expulsion models highlight the importance of Late Tertiary carbonate clinoforms in controlling the generation and expulsion history of effective source rocks in the Browse Basin. The rapid progradation of these carbonates is likely to cause an outward-migrating compaction wave that forces expelled fluids and hydrocarbons to outboard areas. This mechanism may apply elsewhere on the North West Shelf where carbonate clinoforms are similarly well developed, and could provide new exploration opportunities in outboard areas.

Normanton, Qld, 2008 (P1148), radiometric line data, AWAGS levelled

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected 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 Normanton, Qld, 2008 (P1148), radiometric line data, AWAGS levelled were acquired in 2008 by the QLD Government, and consisted of 115883 line-kilometres of data at 400m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

The Delamerian Orogen – An overview of the resistivity structure across scales

Here we present 3D and 2D resistivity models of the lithosphere beneath an area of southeast Australia, derived from Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) data and a subsequent infill broadband MT transect collected in October 2020.
The Flinders Ranges, South Australia, is a zone that has been weakened by multiple Precambrian rift cycles related to the breakup of Rodinia, which may have led to the utilisation of this lithosphere for the focussing of fluid alteration causing high conductivities at crust and upper mantle depths in this region, as imaged in the AusLAMP 3D resistivity models. The northwestern end of a 100 km MT transect traverses this region and its 1.5 km MT site spacing resolves high conductivity pathways that broadly correlate with previously identified mineral prospects. These pathways straddle the resistive granodiorite rocks of the Anabama pluton, known to host porphyry-style mineralisation. To the southeast, the transect images the onlapping Mesozoic Murra

Cobar P5009 EXT 5 total magnetic intensity grid

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 Cobar P5009 EXT 5 total magnetic intensity grid has a cell size of 0.00039074 degrees (approximately 40m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2021 by the NSW Government, and consisted of 53617 line-kilometres of data at 200m line spacing and 60m terrain clearance.

Australian Zn-Pb-Ag Deposits: A basin system and fluid flow analysis - Economic Geology special volume

Paleoproterozoic rocks of northern Australia host one of the world's largest base metal repositories and are the world's most important zinc repository. The McArthur-Mount Isa-Cloncurry mineral belt contains several world-class Zn-Pb-Ag, U, Cu, and Cu-Au deposits (Ewers and Fergusson, 1980; Williams, 1998; Betts et al., 2003; Large et al., 2005; Fig. 1). The province has the potential to host additional base metal and uranium reserves. Advances in exploration techniques in the 1980s led to the discovery of several major new Zn and Cu-Au deposits, including Cannington, Century, Ernest Henry, and Osborne. However, recent exploration results have been disappointing and new exploration strategies are required if the region is to further its growth potential and if new resources are to be realized beneath shallow cover. Between 1975 to 1995 geoscientists from Geoscience Australia, the Geological Survey of Queensland, and the Northern Territory Geological Survey mapped the Paleoproterozoic outcrop belt of northern Australia at a scale of 1:100,000. Subsequently, researchers at Monash University undertook detailed studies of the deformation history of the Mount Isa block, placing the ore deposits within a tectonic context (e.g., O'Dea et al., 1997; Betts et al., 1998, 2003; Betts and Lister, 2002). Researchers at James Cook University carried out structural, metamorphic and mineralization studies across the Mount Isa block, with their principal focus concentrating on the deposits and their immediate environs (Bell et al., 1988; Broadbent et al., 1998; Williams, 1998). Between 1990 and 1998 a multidisciplinary research group based at CODES, University of Tasmania, completed studies aimed at better understanding the origin of the region's zinc deposits and their alteration halos in both the McArthur and Mount Isa regions (Cooke et al., 1998, 2000; Large et al., 1998, 2000, 2005; Garven et al., 2001; Yang et al., 2004). Each of the studies outlined above were based on lithostratigraphic concepts in which rock units were subdivided, mapped, and labeled, but the units defined are diachronous and cannot be used for reconstructions of basin shape and sediment architecture at the times of fluid migration. This requires an event-based chronostratigraphic framework.
