The Bureau of Mineral Resources, Geology and Geophysics (BMR) (now known as theAustralian Geological Survey Organisation (AGSO)) conducted a seismic survey in the centralpart of the Eromanga Basin from early July to late November 1982.
The seismic survey was part of the multi-disciplinary, geoscientific research project on the central Eromanga Basin (Harrison & others, 1980), and was a continuation of the seismic programmes of 1980 (Wake-Dyster and Pinchin, 1981) and 1981 (Sexton and Taylor, 1983).The project aimed to gain knowledge of the structure, stratigraphy and lithology of the Eromanga and underlying sedimentary basins in order to study the geology and tectonicevolution of the area, and to provide basic information to assist in the exploration of the area for hydrocarbons.
The objectives of the 1982 BMR seismic survey were to extend some of the 1980 and 1981seismic lines further east across the Adavale Basin and to provide ties between private oilcompany seismic traverses with a number of important petroluem exploration wells (Figure 1). Some of these objectives were discussed by Mathur and Sex-ton (1981).
Five seismic traverses totalling 485 km of mainly 6-fold CMP reflection coverage wererecorded. These included Traverses 13, 11, 11A, 2 and a northern extension of 10. Gravitymeasurements were taken along these lines as well as Traverses 6, 7, 5, and 12 (1981 traverse lines). An expanding spread (Musgrave, 1962) was recorded along Traverse 10.
This report presents details of operations and preliminary results of the seismic reflectionsurvey only. Operation statistics, spread and recording parameters, and personnel and equipment are listed in Appendices 1 to 3.
Examples of reduced scale copies of the processed seismic sections and expanding reflection
spread are shown in Figures 2 and 3 respectively. Reduced scale copies of the other BMR1982 seismic traverses are shown in Finlayson et al, 1987, with seismic sections both at 0 to 4 seconds two-way travel (TWT) time and 0 to 20 seconds TWT time.
