Pedirka Basin / Eromanga Basin (1 CABS paper):

• Recent studies by the NTGS have highlighted the Early Permian Purni Formation as an important oil source rock which includes a glacigene sandstone at the base. These units correlate with the Patchawarra Formation and Tirrawarra Sandstone respectively, a petroleum system which is important in the Cooper Basin.
• Additional Triassic and basal Jurassic petroleum systems exist, in what is a very sparsely explored basin, and the oil potential of these is believed to be in many ways analogous to the Cooper Basin.

All of the basins described above are largely under explored by international standards. With the exception of the northern Amadeus Basin, this can be attributed initially to the lack of early success in what are complex basins. The latter can be largely attributed to poor seismic control on many of the features drilled. Later, land access problems stalled exploration and it is only over the last decade modern geological and geophysical concepts, including interpretation of modern airborne aeromagnetics coverage, have been applied to basin studies. However most of these basins are a generation behind the levels of exploration seen in North America and elsewhere.
