Tanami 1:250 000, R502 historical topographic map

The R502 series of maps has been replaced by the National Topographic Map Series (NTMS). The R502 series consists of 542 map sheets and covers Australia at a scale of 1:250,000. It was compiled from aerial photography, but only about one quarter of the series was contoured. The standard sheet size is 1 degree of latitude by 1.5 degrees of longitude. Transverse Mercator map projection and Clark 1858 datum were used. Coverage of the country was completed in 1968.

Petrel Sub-basin Biozonation and Stratigraphy Chart No. 1

Biostratigraphy is the branch of stratigraphy that uses fossils to establish relative ages of rock and correlate successions of sedimentary rocks within and between depositional basins. A biozone is an interval of geologic strata characterised by certain fossil taxa. Such intervals are often defined by the first appearances (range bases), apparent extinctions (range tops/last appearances), or abundances of fossil index species. These key index species should be relatively abundant, short-lived taxa that are easy to recognise and as geographically widespread as possible. Widely used fossil groups include brachiopods, conodonts, dinoflagellate cysts, foraminifera, graptolites, nannofossil, spores and pollen and trilobites. Zonal schemes based on several different fossil groups can be used in parallel, and the zones can be calibrated to the absolute geological timescale using tie points to rocks which have been radio-isotopically dated.

Hypocentre locations from a microearthquake survey, Cadoux, Western Australia, 1983

A microearthquake survey around the fault scarp caused by the 1979 Cadoux, Western Australia, earthquake located 36 earthquakes (ML 0-2.4) over 7 weeks from October to December 1983. The earthquakes show a NNE-SSW trend on the westward side of the fault complex, consistent with a westward dipping fault plane. The earthquakes are evenly distributed along the length of the fault. The more accurately located earthquakes are 0-6 km deep.

Where is Australia's petroleum and how long will it last?

Australia has progressed from a continent considered to have little potential for petroleum resources in 1950 to a middle-order oil and gas producer on a worldwide scale in the late 1990s. The Petroleum Search Subsidy Act (1957) encouraged exploration that resulted in discoveries in the Gippsland, Carnarvon, Amadeus, Cooper, Bowen and Surat Basins. Together with the Bonaparte and Eromanga Basins, these basins are now Australias main petroleum producing regions. Subsequently, the Petroleum (Submerged Lands) Act (1967) and various State Acts were passed to manage exploration and production. In Australia, about 7750 million barrels of crude oil and condensate (1230 gigalitres) and 96 trillion cubic feet of gas (2720 billion cubic metres) had been identified to the end of 1996. The Bureau of Resource Sciences (BRS) assessed that between 1320 million barrels (95% probability) and 3440 million barrels (5%) of crude oil remain to be discovered, and between 18 trillion cubic feet (95% probability) and 58 trillion cubic feet (5% probability) of sales gas remain to be discovered. Australias most prospective crude oil basins, ranked in order, are assessed as the Carnarvon, Bonaparte, Gippsland, Browse, Perth, Otway and Eromanga, with speculative potential in the Perth Basin, Otway Basin and other basins. The most prospective basins for sales gas are ranked as Carnarvon, Browse, Otway, Bonaparte, Cooper, Gippsland and Perth Basins. Australias likely ultimate crude oil resource was assessed as being about 52% depleted and sales gas resource as about 10% depleted at mid-1997 (BRS 1998). However, because of the relatively low level of exploration in Australia it is impossible to estimate how long the petroleum resource will last. Approximately 94% of crude oil production and 75% of gas production are from offshore. New production is likely to come mainly from already-known basins with contributions from deepwater areas and possibly the Exclusive Economic Zone.

L032 Haddon Downs experimental seismic survey, SA, 1957

An experimental seismic survey was conducted at Haddon Downs, South Australia, during Octobor and November.1957. The area lies within the Eromanga Sub-basin of the Great Artesian Basin, and at least 5,500 feet of Mesozoic section are known to exist there, part of which is of a marine facies. Preliminary reconnaissance work by geologists of Santos Ltd. which holds an Oil Prospecting Licence over the
area, revealed some large anticlines on the surface. The Company has already completed a limited amount
of gravity work which gives promise of supplying useful information on both regional and detailed subsurface structure.
Two important refractors were recorded which may be useful for semi-regional mapping. A refractor of velocity 10,250 ft/sec. was recorded from a depth of about 2,700 feet, and this may represent the top of the marine Cretaceous section. The second refractor of velocity 17,000 ft/sec. and aidoroximate depth 7,250 feet may be just below the base of the Mesozoic section.
Large multiple geophone arrays and pattern shots were needed to obtain good quality reflections over most of the area, except when shooting on the alluvial plains of the larger creeks. The sedimentary section was shown to be at least 8,000 feet and possibly 16,000 feet thick, The base of the Mesozoic section is interpreted as being 7,250 feet deep on the refraction traverse and 8,600 feet at the south-east end of the reflecta.on traverse. The rest of the section probably consists of Palaeozoic sediments. If so, the high velocity (17,000 ft/sec.) suggests that a dense elastic or crystalline limestone is probably present near the top of them. The structure of the Mesozoic section is subhorizontal, but there may be minor structures with dips less than 1 degree which correlate with the surface structures.

Household experiences of flooding in Brisbane and Ipswich, Queensland: Results of Geoscience Australia surveys following flooding in South East Queensland in 2011 and 2013

In January 2011 extreme flooding occurred in the South-east corner of Queensland resulting in over 17000 homes inundated in the cities of Brisbane and Ipswich. In the weeks following the floods, Geoscience Australia conducted a field survey to assess the scale of the damage on individual homes. The engineering survey was then supplemented with GA's first social survey. This report presents the results of the survey investigating the impacts of the 2011 floods on flooded households in the Brisbane and Ipswich City Councils, combined with the results of a follow up survey conducted following the 2013 floods in the same area. The report chapters cover: warnings and risk perception; preparation, evacuation and returning home; damage and repair; financial implications; and medical impacts, mental health and social support.

National Mapping Helicopter Gravity, Height Survey (P196211), gravity point data

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 National Mapping Helicopter Gravity, Height Survey (P196211) contains a total of 633 point data values acquired at a spacing of 11265 metres. The data is located in NSW, QLD and were acquired in 1962, under project No. 196211 for Australian Survey Office (National Mapping); Bureau of Mineral Resources (BMR).

ICSM LiDAR Acquisition Specifications and Tender Template Version 1.0

Digital elevation data which describes Australia's landforms and seabed is crucial for addressing issues relating to the impacts of climate change, disaster management, water security, environmental management, urban planning and infrastructure design. In recent years dramatic developments in LiDAR technology and industry capabilities have revolutionised our ability to address these issues at the local level. However, inconsistent and diverse product specifications, and variable data quality are often making it difficult to integrate datasets to address regional, state and national issues. In order to optimise investment and the utility of both existing and future data collections there is a need for a national base specification which defines a consistent set of minimum products which ensure compatibility across projects and States.

Barkly - Mongala, NT, 2001 (P1018), 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 Barkly - Mongala, NT, 2001 (P1018), radiometric line data, AWAGS levelled were acquired in 2001 by the NT Government, and consisted of 301463 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.

CO2 EOR-Storage Methodology for Residual Oil Zones

This report represents the first output from a study designed to understand and identify residual oil zones in Australia, with the aim of developing this potential resource using CO2 –EOR techniques. This work is part of the Residual Oil Zone (ROZ) module in the Exploring For The Future (EFTF) programme, which runs from 2020-2024. The work presented here is a collaborative study between Geoscience Australia and CSIRO. 
ROZ potentially represent a new and viable oil resource for Australia, while at the same time providing an additional CO2 storage avenue through application of CO2 enhanced oil recovery (CO2-EOR). These water-saturated reservoirs, which contain a moderate amount of residual oil and resemble water-flooded conventional oil fields, can be associated with conventional fields (brownfields) or occur with no associated main pay zone (greenfields). Both types of ROZ are currently produced commercially through CO2-EOR in the Permian Basin, USA, and are of growing interest internationally, but our understanding of ROZ in the Australian context is lacking. 
The first section of this report identifies and discusses the key parameters and factors that influence the efficiency with which ROZ can be produced. These include fluid-rock and fluid-fluid interactions, which may affect injectivity and sweep of hydrocarbons.  We also discuss the effects of reservoir heterogeneity as it relates to flow dynamics and also the effects of pore space configuration.  The first section concludes with a discussion of CO2 storage associated with ROZ development. In the second section, we discuss two different injection strategies with which to develop ROZ; carbonated brine injection and water alternating gas injection. 
The final section outlines details of the workflow that will be applied in the EFTF ROZ module over the coming years. Our proposed workflow is a three pronged approach which involves core flooding experiments, pore scale modelling and petrophysical analysis to identify potential ROZ in key Australian basins. In addition to plain CO2 injection, two other promising EOR techniques namely CO2-WAG and carbonated brine injection are also considered in this workflow. The main objectives of this workflow are to:
•   assess and identifying estimated oil recovery potential from a target ROZ by either of three EOR injection strategies, 
•   identify the best injection strategy for a ROZ
•   identify the CO2 storage and utilization potential

AUSGeoid98 v.1.0 data files:  (sj50)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.
