The Exploring for the Future program is an initiative by the Australian Government dedicated to boosting investment in resource exploration in Australia. As part of the Exploring for the Future program, this study aims to improve our understanding of the petroleum resource potential of northern Australia. This data release presents new field emission scanning electron microscopy (FE-SEM) of broad ion beam- polished samples (BIB-SEM) to visualise mineral and organic matter (OM) porosity on 15 Proterozoic aged shales. Samples were selected from the Velkerri and Barney Creek formations in the McArthur Basin and the Mullera Formation, Riversleigh Siltstone, Lawn Hill and Termite Range formations in the South Nicholson region. Qualitative maceral analysis of the 15 samples are described in addition to bitumen reflectance measurements. These samples were analysed at the Montanuniversität Leoben, Austria in June 2020. The results of this study can be used to improve our understanding of porosity, microstructures, seal capacity and hydrocarbon prospectivity of Proterozoic aged sedimentary basins in northern Australia.
