Dumbleyung detailed, WA, 2008 (P1177), 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 Dumbleyung detailed, WA, 2008 (P1177), radiometric line data, AWAGS levelled were acquired in 2008 by the WA Government, and consisted of 75805 line-kilometres of data at a line spacing between 100m and 400m, and 60m 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.

Aspects of landscape history and regolith in the Kalgoorlie region, Western Australia

The regolith of the Kalgoorlie region includes saprolite in deep weathering profiles, and a range of surficial deposits, including colluvium, alluvium, and duricrusts, the distribution of which is the result of a long geological and geomorphic evolution. The generally accepted model of landscape evolution, with an old lateritised plateau being replaced by a younger plateau, is shown to be oversimplified.  Features in the saprolite indicate changes in the former position of water tables. Sand plains are essentially confined to areas of granite; and red earths, to greenstone belts. Neither of these appears to have any significant aeolian component. Ferricrete is generally unconformable over various substrates: it originally formed on lower slopes, and occupies high sites in the present landscape because of repeated inversion of relief. Silcrete appears to have the same landscape relationships. In a new geomorphic chronology of the region regolith formation is treated as an integral part of the geological history since the Permian.

Bathurst NSW 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 Bathurst NSW magnetic grid geodetic has a cell size of 0.0005 degrees (approximately 51m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1991 by the NSW Government, and consisted of 68244 line-kilometres of data at 250m line spacing and 80m terrain clearance.

Site Classification and VS30 Determination for Seismic Hazard Evaluation in the SWAN Seismic Network, Western Australia

&nbsp;Seismic site classification is essential for seismic hazard analysis as it helps constrain the impact of local geological conditions on the near-surface seismic-wave propagation and observed ground motion. The Southwest Australia Seismic Network (SWAN) temporary array was established to record local earthquakes for seismic hazard applications and to improve rendering of the 3D seismic structure of the crust and mantle lithosphere in southwestern Australia. Notably, the SWAN project has recorded significant seismic events, including the 2022 Arthur River earthquake sequence and the 2023 MW 5.0 Gnowangerup earthquake. These earthquakes, together with other well-recorded events across the SWAN network, offer a rare opportunity to assess the utility of published ground-motion models (GMMs) for large-magnitude earthquakes, thereby significantly improving seismic hazard assessment in the region. Moreover, the importance of site classification is underscored as it is a critical component of GMMs, and can substantially enhance the accuracy and reliability of these models. This study uses microtremor survey methods to estimate the shallow shear-wave velocity profiles and VS30 values, which are the primary factors for site classification at seismic stations. Microtremor array measurements, such as high-resolution frequency-wavenumber and modified spatial autocorrelation methods, were utilized to analyse ambient vibrations, producing detailed dispersion curves for each station. To enhance the depth accuracy of velocity profiles, ellipticity curves were extracted using the RayDec method and jointly inverted with the dispersion curves. Additionally, OpenHVSR software was employed for the inversion of single-station ellipticity curves.

Carnarvon Basin (Barrow Sub-basin) Geochemical Calibration Survey : Project 121.18

Transglobal Environmental Geosciences (TEG) and the Bureau of Mineral Resources,as part of the Joint Research Agreement into hydrocarbon seepage around theAustralian Continental margin, conducted a calibration survey over some knownhydrocarbon accumulations in parts of the Barrow Sub-basin and the Ranldn Platformduring 1989. This survey was conducted at the end of a larger and proprietarygeochemical 'sniffer' survey conducted by TEG (for Amoco Production Co., USA) inthe Perth Basin.
Approximately 220 line km of Direct Hydrocarbon Detection (DHD) data werecollected during the survey in the vicinities of known hydrocarbon accumulations,Saladin, South Chervil, Chervil, North Herald and South Pepper in the inshore part ofthe Barrow Sub-basin. Additional survey lines were run in the deeper water part of thebasin, on the landward side of the rift, in the vicinities of Chinook and Griffin, andfurther to the north, on the southern extension of the Rankin Platform (Alpha Arch)over the Gorgon gas/condensate field.
Light hydrocarbon anomalies were detected in bottom-waters in the vicinities ofSaladin, Chervil, South Chervil, North Herald and South Pepper, although theanomalies were generally weak (&lt; five-fold background). No anomalies were detectednear Chinook and Griffin, nor Gorgon, although problems with the tow-cable and tow-fish resulted in the tow-fish being too high above the seafloor to detect any significantseepage.

Potential from enhanced oil recovery applications in Australia

As a result of a Society of Petroleum Engineers/National Energy Research Demonstration and Development Council (NERDDC) meeting in Adelaide in April 1986 between Australian oil industry representatives. researchers and government, it was decided to propose a NERDDC project on the potential from Enhanced Oil Recovery (EOR) applications in Australia. The aim was to highlight to government, industry and the public the scope for EOR, and to provide assistance in planning EOR projects and policies. The specific project objectives were to identify the most likely field prospects for EOR applications and to assess the additional oil which may be recovered under various recovery techniques at selected oil prices.  Oilfield data from 177 significant reservoirs were compiled, checked for consistency, and subjected to technical screening, reservoir simulation and preliminary economic evaluation.  For Australias reservoirs discovered before June 1988, the "target" for EOR (i.e. oil-in place minus reserves) is estimated as 3914 million barrels. Of this, 2346 million barrels is offshore where miscible or immiscible processes appear to be most promising. 1568 million barrels is onshore, where miscible/immiscible gas flooding is applicable and where, in the event of technical or economic improvements, waterflooding with polymers may be applicable. A preliminary and optimistic estimate of economically recoverable oil at current prices is 709 million barrels. Results for individual fields have been given to the operating companies concerned.  A major issue of concern is premature abandonment of existing wells and facilities, which can preclude future EOR opportunities

The 2023 National Seismic Hazard Assessment for Australia: Model Input and Output Data

This Geoscience Australia Record contains technical data and input files that, when used with the Global Earthquake Model’s (GEM’s) OpenQuake-engine probabilistic seismic hazard analysis software (Pagani et al., 2023), will enable end users to explore and reproduce the 2023 National Seismic Hazard Assessment (NSHA23) of Australia (Allen et al., 2023b). Output data, as calculated by Geoscience Australia using Version 3.16.1 of the OpenQuake-engine, are also provided. This report describes the NSHA23 input and output data only and does not discuss the scientific rationale behind the model development or the development of the NSHA23 earthquake catalogue. These details are provided in Allen et al. (2023b) and (Allen et al., 2024), and respective references therein. The NSHA23 provides estimates of seismic hazard for the six Australian states and two mainland territories. However, it does not provide updated hazard factors for Australia’s Antarctic and other offshore territories (e.g., Christmas Island, Cocos Island, Heard Island, Lord Howe Island, Macquarie Island and Norfolk Island).
