On 12th July 1960, a velocity survey of the A.A.O. Pickanjinnie No. 1 bore was made by the Bureau of Mineral Resources. The bore had been drilled to a depth of 5218 ft and was surveyed to the bottom. The average velocities for the Mesozoic rocks and the Timbury Hills Formation are similar to those measured in the Timbury Hill No. 2 bore. However, it seems impossible to correlate individual units within the Mesozoic sequence according to their velocity.

Following a month of preliminary experimental seismic work in the latter part.of 1964 the Bureau of Mineral Resources carried out a reconnaissance seismic survey of the southern part of the Georgina Basin, mainly in the Northern Territory, from April to October 1965. In most areas reflections proved very difficult to obtain. A number of different techniques were tried, including various shot andgeophone pattern arrangements, noise testing,collinear offset shooting, airshooting and multiple coverage, but no technique was found which was generally successful in providing useful reflections. The seismic results tended to confirm gravity indications that there is a shelf area between BMR 12 Bore and Tobermory and provided no indications that there are deep Palaeozoic troughs similar to the Toko -Syncline in the survey area.

<p>Geoscience Australia conducted a seismic, gravity and aeromagnetic survey in Central Australia, Northern Territory from July to November, 1985. The objectives of this multidisclipinary experiment were to investigate the structural evolution of the lithosphere in the Central Australian region with emphasis on the formation of the Ngalia and Amadeus Basins, and secondly to aid in the evaluation of the petroleum prospectivity of the basins. 486 km of six-twelve fold common mid-point (CMP) seismic reflection data were collected, from four traverses.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74968</b>

The Bureau of Mineral Resources conducted a seismic reflection survey of a small area near Broome, W.A., during 1954 and 1955. It was part of a general investigation of the Canning Basin and was aimed at determining the distribution of sediments south of the Fenton Fault. The seismic work indicated a sedimentary thickness of at least 6000 feet, and probably as much as 10,000 feet could be expected. It also showed that the subsurface formations are probably folded and faulted.

The Bureau of Mineral Resources seismic party carried out a seismic survey in the Bonaparte Gulf area of north-western Australia between 16th June and 13th October, 1956. The initial objects of the survey were to obtain regional information on the thickness of the sedimentary rocks and on the tectonics of the Bonaparte Gulf Basin, and to establish the applicability of the seismic method in the area. During the course of the survey the party was directed to transfer its attentions to obtaining some detailed information on the Spirit Hill Anticline. This latter work was carried out in response to an application by Westralian Oil Pty. Ltd., which was anxious to select sites for a test boring programme. The seismic results indicate a maximum thickness of sediments of about 20,000 feet in the Carlton Basin and 14,000 feet in the Burt Range Basin. The rocks in both these basins have been folded to a considerable extent and the reflections suggest unconformities within both basins. The seismic reflection method proved successful in indicating geological structure at depth in most of the areas tested.

<p>Geoscience Australia conducted a deep reflection seismic profiling survey in the onshore portion of the Otway Basin in the southeastern part of South Australia and southwestern part of Victoria, form February to June 1992. The seismic survey formed part of a National Geoscience Mapping Accord (NGMA) project to study the early development of the Otway Basin. The objective of the seismic survey was to acquire a new deep reflection seismic data using explosive seismic energy sources to improve on the knowledge of early sedimentary sequences in the Otway Basin, especially at depths greater than 3 km. The seismic survey obtained 461 km of 5 to 10 fold Common-Middle-Point (CMP) deep reflection seismic data.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74947</b>

1997 Victoria Grampians 2D seismic survey operations were performed for the Australian Geological Survey Organisation (now Geoscience Australia). The survey was conducted during April 1997. The survey consists three lines, covering 68.96 km. The Victoria Grampians seismic survey was a component of the Australian Geodynamics Cooperative Research Centre (AGCRC) VicGold project. This was a multidisciplinary project with the aim of influencing the economic development of the world class western Victorian gold province.

<p>Geoscience Australia conducted a seismic reflection, seismic crustal refraction and gravity survey in southeastern Queenland from August to November 1986. The primary objective of the survey was to complete seismic reflection coverage in the Dalby-Toowoomba area between Traverse 14 and Traverse 16 recorded during the BMR S.E. Queensland seismic survey in 1984. Secondary objectives, subject to survey progress included recording additional seismic reflection data east of Traverse 16 (1984). Overall the survey objectives would allow the completion of a continuous deep crustal seismic reflection profile of 1110 km length across southern Queensland, the basis of a lithospheric transect study in the southern region of Queensland. The survey obtained a total of 181 km of six-sixteen fold Common-Middle-Point (CMP) seismic reflection data in the Beenleigh, Darling Downs and Mitchell areas, using the Sercel SN368 seismic acquisition system.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74962</b>

The Bureau of Mineral Resources made three seismic surveys in the Ngalia Basin, Northern Territory, during 1967 to 1969 as part of a comprehensive geological and geophysical investigation of the structure and stratigraphy of the basin. L079 is the first survey done in 1967. The project was aimed at delineating the configuration of the basin, within which outcrops are sparse, and providing information pertaining to its depositional and tectonic history. Investigation of the extent of Lower Palaeozoic sedimentation was considered to be important in assessment of the petroleum prospects of the basin.

A seismic reflection traverse on portion of the Giralia anticline was conducted by the Bereau of Mineral Resources (BMR). This work constitutes a part of a general programme of investigation which the BMR, Geology and Geophysics, has been carrying out on Permit areas held by Ampol Petroleum Ltd. in this area. The purpose of the survey is to idenfy the proposed geology structure in this region based on the previous geology surveys.
