A seismic survey was made in the.Ooraminna area of the Amadus Basin 9 Northern Territory 9 by a seismic party of the Bureau of Mineral Resources 9 Geology and Geophysics 9 between 6th July and ,29th August 1962. Reflection traverses were recorded between Deep Well and Alice Springs and across the culmination of the Ooraminna Anticline l and a refraction depth probe was recorded on the crest of the Ooraminna Anticline. The purpose of the survey was to obtain information on the structure of the Basin in the eastern part of the Missionary Plain, and on the structure of the Ooraminna. The Basin was shown to be generally synclinal between Deep Well and Alice Springs with a maximum sediment thickness Of 20,000 feet north of the Ooraminna Anticline. Seismic evidence suggested that the uplift at Deep Well and the Ooraminna Anticline have resulted from thickening in a deep formation, which has been tentatively identified as the Bitter Springs Formation. The survey was unsuccessful in relating reflectors in the crosssections with outcropping formations in the MacDonnell Ranges and on the Ooraminna Anticline.

Trace Energy Services was contracted by the Australian National Seismic Imaging Resource (ANSIR) to conduct the WA seismic 2004 survey in the eastern & northern Goldfields region of Western Australia. There were 148.59 km of 2D seismic reflection data recorded, 137.54 km over 29 traverses using Litton 315 Paystars and 11.05 km over 5 traverses using a single IVI Minivib as source. All lines were situated within the lease boundaries of gold mining companies, namely, Sons of Gwalia (Tarmoola & Gwalia) (L165), Placer Dome (Kanowna Belle, Wallaby, Granny Smith, Lancefield & Mt Morgans) (L166), Anglo Gold (Sunrise Dam) (L167) and Goldfields (St Ives at Kambalda) (L168), <b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74865</b>

Efforts are underway to digitally preserve seismograms, magnetograms and geomagnetic absolute observations from Australian observatories. These datasets are stored in original paper and film form and although they are available on request they are not easily discoverable or available at short notice to the public. The retrieval of analogue media is both time-consuming and labour-intensive and can cause further damage to deteriorating records. In this poster, we detail preserved examples of the handwritten records, microfilm, as well as original paper records dating back to 1959 for magnetograms from Wilkes Geomagnetic Observatory, and to 1902 for seismograms from Melbourne Observatory. Different generations of collected data have challenges associated with the preservation efforts, including; legibility, data compression algorithms, stability of the original medium and associated metadata. Additionally, costs and expertise required to create digital copies varies greatly between the different original mediums of data recordings. Our ongoing efforts have prioritised the preservation of the original analogue data through creation of digital copies before the record suffers from further deterioration, and, making those digital records publicly accessible through Geoscience Australia’s data servers to improve discoverability. Long term efforts following this will then be focused on digitisation for use with modern data analysis techniques. Presented at the 2022 Australian Earthquake Engineering Society (AEES) Conference.

Terrex Seismic was contracted by Geoscience Australia to conduct the Papunya 2D Seismic Survey. Acquisition commenced on the 27th of September 2010 and was completed on the 28th of September 2010.

The collection consists of field, processed and navigation seismic data plus acquisition processing and interpretation reports. The collection is derived from the marine seismic field programs undertaken by Geoscience Australia, Australian Geological Survey Organisation (AGSO) and Bureau of Mineral Resources (BMR) since the 1980s. Data used by petroleum industry for exploration, GA for frontier petroleum programs and academia for research. 80% of data requests from industry.

A seismic velocity survey of the APM Development Pty Limited No. 1 bore at Rosedale, Victoria, was made by the Geophysical Branch of the Bureau on the 3rd May 1960 using a TIC three-component well geophone. Measurements were taken with the geophone suspended in the well at selected intervals down to 5500 ft. It was apparent that signals reached the geophone by transmission along the cable by which it was suspended, and these interfered with the signals reaching the geophone along a path directly through the ground. This made interpretation difficult; however, by careful inspection of both the vertical and horizontal components of the signals received by the geophone at each depth, an interpretation has been made that yields a series of velocity/depth determinations. The average vertical velocity increases from 5000 ft/sec at the surface to 8930 ft/sec at a depth of 5500 ft. The average velocity in the Tertiary (0-2159 ft below datum) was computed to be 6420 ft/sec; the -werage velocity in the Mesozoic rocks penetrated (2159-5314 ft below datum) was 12,180 ft/sec. Two reflection spreads laid out and recorded in the vicinity of the bore showed the presence of reflectors at depths estimated to be in excess of 7700ft.

On 30th March 1960, a seismic velocity survey was made in the A.A.O. Timbury Hills No. 2 bore, jointly by the Bureau of Mineral Resources and Associated Australian Oilfields N.L. The bore had been drilled to a depth of 4400 ft and was surveyed to a depth of 4304 ft below the rotary table. There remains a doubt whether the breaks recorded on the well geephone were, in fact, cable breaks, particularly between 2300 and 3305 ft below the rotary table. The interpretation has boon made with the belief that true breaks wore recorded. Average and interval velocities were computed and are acceptable geologically. Sandstones, particularly cemented ones, have Renerally higher velocities than shale. The average velocity of the Mesozoic sequence is about 9800 ft/sec. A velocity of 17,980 ft/sec was measured at the bottom of the bore and corresponds to the Timbury Hills Formation of unknown age. The Moolayember Shale has a low velocity calculated as 8360 ft/sec.

An experimental seismic survey was conducted at Surat, Queensland, on behalf of the Australisa Oil and Gas Corporation Limited during a five week period from May 28th to July 2nd. 1958. The area lies within the southeastern portion of the Great Artesian. Basin on Authority to Prospect No. 36P and, sel the evidence of numerous bores near Roma, and a few other scattered bore logs, is considered to contain sediments suitable for the generation and accumulation of hydrocarbons in possible, economic vantities. A local geological survey by the Australian Oil & Gas Corporation suggested a structure of considerable dimensions - the 'Weribone Uplift' - which, if substantiated, would provide a promising location for a stratigraphic test bore. The experimental survey conducted by the Bureaushowed that useful results could be obtained throughout the area by conventional methods of reflection and refraction shooting. The reflection shooting indicated a fairly uniform sedimentary section with generally flat-lying beds and a probable total thickness of 7,000 to 8,000 feet. The refraction work recorded several velocities: including one near 19,000 f/s which is assumed to be a basement velocity. Depths measured to this high Velocity refractor support the estimate of the thickness of sediments made from the reflection cross-section and indicate 4 south component of dip of about 40 ft. per mile across the area surveyed. Neither the reflection nor the refraction work gave any evidence for the existence of the 'Weribone Uplift'. However, the more northerly refraction traverse indicated a local component of north dip at basement depth, and a single reflection record shot along that traverse suggested a substantial thickening of the deeper sediments towards the north. Insufficient seismic work was done to estimate the northwards extent of this dip. Such limited evidence might well indicate a purely local irregularity in basement topography. On the other hand, the north dip could be extensive, and therefore structurally significant. Any further seismic work contemplated in this area should be directed, in the first instance, towards checking this possibility.

Between February and May, 1957, an experimental seismic reflection survey was made in the Sydney Basin by the Bureau of Mineral Resources to test the applicability of the method in that area and to investigate the sedimentary section. The work done at four different locations is described and the seismic results obtained are discussed in relation to the known geology. In general, the seismic method proved applicable in the Sydney Basin. The use of multiple geophone and shot-hole techniques proved desirable in some areas, notably on the Hawkesbury Sandstone. The seismic work indicated the existence of sediments up to 15,000 feet thick. Insufficient seismic work was done to prove the existence of individual structures suitable for the accumulation of oil or gas.
