Description

The Eromanga Basin is a large Mesozoic sedimentary basin in central and northern Australia. It covers parts of Queensland, the Northern Territory, South Australia, and New South Wales, and is a major component of the Great Artesian Basin. The Eromanga Basin covers 1,000,000sq km and overlaps part of the Cooper Basin.

Summary

The Basin remains under-explored due to the perceived lack of mature petroleum source rocks and large distances from recognised source kitchens all contributing to the lack of exploration efforts. Reprocessing of geophysical data and newly acquired seismic data have shown the existence of previously unrecognised troughs beneath the Eromanga Basin. The pre-Mesozoic fill of these structures is considered to be mainly Devonian aged, although possibilities for Permian-fill have been identified.
