Australia’s longest onshore seismic line (18GA-KB1) across the southern Canning Basin informs resource evaluation of the frontier Kidson Sub-basin and Waukarlycarly Embayment. The Kidson Sub-basin covers 91 000 km2 and has a sag basin architecture. Preliminary interpretation of the seismic data indicates that the sedimentary basin is approximately 6 km deep, and includes a conformable package of Ordovician–Devonian siliciclastic, carbonate and evaporite facies of exploration interest. Located in the western end of the seismic line, the newly drilled deep stratigraphic well Waukarlycarly 1 penetrated 2680.53 m from the rotary table of Cenozoic and Paleozoic strata in the Waukarlycarly Embayment. This abstract reviews the Larapintine petroleum systems and discusses their possible extension into this frontier region. Recently published geochemical analyses of source rocks, oils and gases produced from exploration wells are coupled with new data on fluid inclusion gases (FIGs) from sedimentary sections in untested petroleum wells to provide correlation to hydrocarbons migrating within data-poor areas of the basin. Amplitude anomalies on the seismic line suggest the possibility of gas in the Waukarlycarly Embayment. Integration of the seismic derivative data with the results of the FIG analyses have determined the widespread generation of gas from Paleozoic sources within the Canning Basin, extending the spatial extent of the three petroleum systems described from the Lennard Shelf, Fitzroy Trough and Broome Platform.
