Abstract
This study assesses the petroleum potential of the Paleo–Mesoproterozoic Birrindudu Basin in the northwestern Northern Territory, which is one of several Proterozoic basins in northern Australia with the potential to host conventional and unconventional petroleum accumulations. Historical source rock geochemistry, porosity, and permeability data from the Birrindudu Basin are collated and interpreted; in addition, new fluid geochemistry is interpreted within the context of the greater McArthur Basin. The limited data available indicate that at least four formations have good or excellent present-day organic richness (>2 wt% TOC), and several sandstone and carbonate reservoirs have good porosity data. The calculated brittleness index of a number of organic-rich shales suggests that several are likely to be favourable for fracture stimulation and therefore might constitute good unconventional hydrocarbon targets. Four continent-scale petroleum supersystems are identified, two of which are described for the first time. These supersystems are an important tool in understanding the petroleum potential in frontier basins with limited data. Additionally, a number of basin-scale petroleum systems are potentially present within the basin successions; 14 possible conventional systems and 9 possible unconventional systems are documented. Petroleum play concepts are also described to assist with assessing the potential for conventional and unconventional hydrocarbon resources. The ultimate aim is to identify areas that can be targeting for precompetitive geoscience data acquisition, so as to reduce the exploration search space.
