This report summarises the output of a joint research project arranged between the South Australian Centre for Geothermal Energy Research (SACGER) at the University of Adelaide and the South Australian Department for Energy and Mining (DEM), and presents new geophysical, geochemical and rock property data acquired from 14 drillholes located in areas of data paucity across South Australia. The main objective of this joint research project was to create a series of data rich ‘control’ or ‘ground-truth’ wells spread across these areas, in order to progress geological and geophysical understanding of the shallow crust. This aim was achieved through the acquisition, processing and interpretation of new wireline log data (e.g. borehole imaging/scanning, MST, full wave sonic) and by making petrophysical measurements (e.g. gamma radiation, density, resistivity, magnetic susceptibility, p-wave, thermal diffusivity) on corresponding drill core, sourced from historical and newly completed open_to_re-entry drillholes. Collection and collation of these data were facilitated both by a grant received from the Australian Geophysical Observing System (AGOS) Subsurface Observatory and by the provision of in-kind analytical services at the AGOS Subsurface Observatory Petrophysics Laboratory based at the School of Earth Sciences, University of Melbourne.
