SA Exploration Initiative - Area B3, SA, 1993 (P701), 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 SA Exploration Initiative - Area B3, SA, 1993 (P701), radiometric line data, AWAGS levelled were acquired in 1993 by the SA Government, and consisted of 75571 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.

Tsunami caused by submarine mass failure - case study of Heard Island and McDonald Island, Australia

Worldwide, volcano sourced tsunami account for around 6% of tsunami events. Tsunami generated by volcanoes can be a far-field source which is often overlooked in hazard assessments. There are several mechanisms for volcanic-tsunami events; underwater explosion, blasts, pyroclastic flows, caldera collapse, subaerial failure and submarine failure.  A key component in including these events in hazard assessments is being able to identify and characterize the potential source volcanoes. Analysis of remote sensing data can be used to determine topography, collapse scars, thermal anomalies, past lava flows and slope profiles. We have developed a framework using the remotely sensed data combined with volcano type and water depth to determine the possible tsunami generating mechanism.
Australia is often seen as a country which does not have high exposure to tsunami or volcanic hazards. The framework described above was applied to Heard Island and McDonald Island (HIMI), an Australia external territory approximately 4000 km south west of Perth, Australia, in the Kerguelen Plateau. There are multiple volcanic edifices in this area, including those with evidence of previous collapse events suggesting that the occurrence of a submarine mass failure is possible and could potentially generate a tsunami. Remote sensing analysis and data from past events in other locations was used to determine the volume that could potentially fail. Two scenarios were then determined for modelling; the first being a submarine mass failure on McDonald Island with a volume of 40km3 (analogous to a past event near Reunion Island), with the second being a submarine mass failure on the Northern Kerguelen seamount with a volume of 230 km3 (analogous to a past event on the Hawaiian Ridge). 
The initial mass movement that generates the tsunami was modelled as a slide using the predictive submarine slide equations of Grilli and Watts (2005) and Watts et al. (2005). The deep water propagation of the tsunami has been modelled using URSGA which solves the linear shallow water wave equation; with inundation modelled using ANUGA which solves the non-linear shallow water wave equations. Preliminary results show that it is possible for both of these scenarios to trigger a tsunami that can be detected along the south west Australian coast and in Antarctica. The modelling predicts that the first wave of the tsunami wave train takes approximately six hours to reach near shore Perth. This poses a potential tsunami hazard to Australia, but more work needs to be undertaken to understand the mechanism and likelihood of such events.

Cooper Basin South Complete Bouguer First Vertical Derivative Grid geodetic

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Cooper Basin South Complete Bouguer First Vertical Derivative Grid geodetic is a complete Bouguer anomaly grid for the Cooper Basin South Gravity Survey, Queensland 2007 (P200741). A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.  This gravity survey was acquired under the project No. 200741 for the geological survey of QLD. The grid has a cell size of 0.0075 degrees (approximately 787m). A total of 9215 gravity stations were acquired to produce this grid.

U-K-A. Cabawin No. 1, Queensland Of Union Oil Development Corporation Kern County Land Company And Australian Oil And Gas Corporation Limited

Union-Kern-A.O.G. Cabawin No. 1 spudded on 6th October, 1960, was drilled as a structural test of the petroleum potential of sediments underlying a major unconformity within the Surat Basin. The age and nature of the section below the unconformity was questionable prior to drilling the well, but it was presumed to be partly Triassic and partly Permian in age and related to the sedimentation of the Bowen Geosyncline. The drilling of the well confirmed this prognosis.
In addition to providing stratigraphic information related to the petroleum potential of the Bowen Group, the well also provided information of regional significance on the Mesozoic rocks of the Great Artesian Group. Under a thin veneer of Tertiary rocks the drill penetrated the Roma, Blythesdale, Walloon and Bundamba Formations of the Great Artesian Group, and the Cabawin, Kianga, and Back Creek Formations of the Bowen Group, before bottoming in volcanic rocks of (?)Permo-Carboniferous age at a depth of 12,035 feet.
The drilling of the well confirmed the presence of hydrocarbons in the Surat Basin. During the drilling operation a blowout occurred at a depth of 9938 feet, surfacing free gas and condensate. The blowout was caused by formation pressures, in excess of the mud weight, within an eight-foot sand body of the Permian Kianga Formation. In addition significant gas shows and a flow of salt water were encountered in weathered andesite of the Cracow Formation. Minor gas shows were recorded in the Permian Back Creek Formation, and in the Lower Triassic Cabawin Formation, and Significant shows of hydrocarbons were also present in porous and permeable sandstones of the lower member of the Triassic-Jurassic Bundamba Formation.
The number of occurrences of oil and gas showings indicated that only a sustained testing programme through casing would properly evaluate the potential of these hydrocarbons. After reaching total depth, 5 1/2" casing was cemented at 12,033 feet, and there followed a series of production tests of all significant shOWings of oil and gas encountered during the drilling operation. Results were negative with the exception of the one zone in the Permian Kianga Formation. This zone proved to be the only producing horizon. After 22 days of continuous production, this zone was producing 62 barrels per day of 490 API gravity crude through 22/64" choke, with casing and tubing well-head pressures at 550 p.s.i. and 300 p.s.i. respectively, and 534 Mcf/D of gas. A total of 1761 barrels of crude oil and 13,744 Mcf of gas were produced during the testing period. Pressure and temperature surveys were
conducted, and the well was shut in and suspended on 17th June, 1961, retained in a condition for production at any future time.

Murrindal, Vic, 1996 VIMP Survey (GSV3060) (P691), magnetic line data, AWAGS levelled

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.
 These line dataset from the Murrindal, Vic, 1996 VIMP Survey (GSV3060) survey were acquired in 1995 by the VIC Government, and consisted of 15589 line-kilometres of data at 200m 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.
