A regional hydrocarbon prospectivity study was undertaken in the onshore Canning Basin in Western Australia as part of the Exploring for the Future (EFTF) program, an Australian Government initiative dedicated to driving investment in resource exploration. As part of this program, significant work has been carried out to deliver new pre-competitive data including new seismic acquisition, drilling of stratigraphic wells and the geochemical analysis of geological samples recovered from exploration wells. A regional, 872 km long 2D seismic line (18GA-KB1) acquired in 2018 by Geoscience Australia (GA) and the Geological Survey of Western Australia (GSWA), images the Kidson Sub-basin of the Canning Basin. In order to provide a test of geological interpretations made from the Kidson seismic survey, a deep stratigraphic well, Barnicarndy 1, was drilled in 2019 in partnership between Geoscience Australia (GA) and the Geological Survey of Western Australia (GSWA) in the Barnicarndy Graben, 67 km west of Telfer, in the South West Canning Basin. Drilling recovered about 2100 m of continuous core from 580 mRT to the total driller’s depth (TD) of 2680.53 mRT (Normore and Rapaic, 2020). An extensive analytical program was carried out to characterise the lithology, age and depositional environment of these sediments. This included detailed organic geochemistry including isotopic and biomarker analyses of core samples. In order to determine the possible presence of organic contaminants in core samples that may jeopardise interpretation of results, manufactured products used during drilling and sample processing were identified as potential sources of hydrocarbon contamination and were investigated for their hydrocarbon content. In addition, in order to test if any hydrocarbon contamination was occurring due to contact with these manufactured products, water samples from the sumps and surface samples of drill muds from specific depths were collected and analysed as well.
