In the South Nicholson region of Queensland and the Northern Territory, the Paleoproterozoic Isa Superbasin and the Mesoproterozoic South Nicholson Basin have the potential to host both conventional and unconventional petroleum systems (Gorton & Troup, 2018). The region remains poorly explored however with only 19 petroleum wells drilled in total (Carr et al., 2016). Although nine stratigraphic intervals are described as potential source rocks, data coverage is extremely limited and a large proportion of the available data is old and of poor quality. To more comprehensively characterise these organic rich source rocks, higher resolution coverages of pre-competitive geochemical data is required (Jarrett et al. 2018).

This report contains the total organic carbon (TOC) content and Rock-Eval pyrolysis data of 674 samples selected from twelve drill cores housed in the Geological Survey of Queensland’s Brisbane core repository including Amoco DDH 83-1, Amoco DDH 83-2, Amoco DDH 83-3, Amoco DDH 83-4, Argyle Creek 1, Armraynald 1, Burketown 1, Desert Creek 1, Egilabria 1, Egilabria 2 DW1, Egilabria 4, Morstone 1, MORSTONE DDH1. This data was generated at the Isotope and Organic Geochemistry Laboratory at Geoscience Australia as part of the Exploring for the Future program.
