The Darling Basin is an attractive sedimentary basin to explore for petroleum. Historically exploration in the basin has been challenging, however new interpretations, new data and similarities with the geology of the Gilmore Gas Field provide a fresh perspective for exploration.

The new Darling Basin Data Package aims to assist exploration with new and updated information. It includes:

  • data from three new wells, six new seismic surveys, recent geochemical surveys and all available data.
  • all relevant reports  bookmarked and searchable to allow easy navigation.
  • databases and summary tables  created to allow a quick assessment of available data and its format.
  • well geophysical logs that, where possible, have been converted to LAS format.
  • a Kingdom® seismic project with major seismic lines and well data that has led to new interpretations of horizons within the basin.
  • an ArcGIS map created with new layers including geochemical surveys and historic titles.

In addition, all well stratigraphy has been reviewed using palaeontological and seismic interpretation and the regional stratigraphy has been aligned with new work completed in the Koonenberry Belt and the Nymagee areas to the west and east of the Darling Basin.

Newly interpreted stratigraphic and structural plays could be potential exploration targets. The sub-basins with the best exploration targets appear to be within the Bancannia, Neckarboo and Pondie Range troughs.

Information on the Yathong Trough has improved dramatically with three seismic surveys conducted since the release of the last data package. Regional lines acquired by the NSW and federal governments have provided a better understanding of the subsurface basin. The trough appears to be a reasonable exploration target with potential traps mapped at depth. Potential source rock has been interpreted from the seismic data and correlates with rock samples encountered in copper exploration boreholes on the eastern flank of the trough.

The new Darling Basin Data Package is currently available on an external drive. An online version will be available soon which will allow for quick and regular updates, and the inclusion of new data.
