Abstract

The Onshore Energy Security Program, funded by the Australian Government and conducted by Geoscience Australia, has acquired deep seismic reflection data, in conjunction with state and territory geological surveys, across several frontier sedimentary basins to stimulate petroleum exploration in onshore Australia. Here, we present data from two seismic lines collected in South Australia and the Northern Territory. Seismic line 08GA-OM1 crossed the Arckaringa and Officer Basins in South Australia and the southernmost Amadeus Basin in the Northern Territory. Seismic line 09GA-GA1 crossed the north eastern part of the Amadeus Basin and a complete section across the southern Georgina Basin in the Northern Territory. Structural and sequence stratigraphic interpretations of the seismic lines will be presented here, eventually leading to an assessment of the petroleum potential of the basins. In seismic line 08GA-OM1, the Carboniferous to Permian Arckaringa Basin is imaged as series of depocentres forming the Phillipson Trough, with a much thinner succession connecting the depocentres, and extending well to the north. It is overlain by a thin cover of the Mesozoic Eromanga Basin and Cenozoic sediments. Seismic line 08GA-OM1 also crosses the Neoproterozoic to Devonian eastern Officer Basin. The basin is structurally complex in this area, being dominated by south-directed thrust faults and fault-related folds, providing potential for underthrust petroleum plays. The northern margin of the basin is overthrust by the Mesoproterozoic Musgrave Province. To the north, the Moorilyanna Trough is a major depocentre up to 7000 m deep.
