Petroleum systems modelling services

Geoscience Australia is in the final stages of a four-year initiative by the Australian Government called Exploring for the Future (EFTF). The aim is to boost investment in resource exploration in northern Australia. A key component of this is improving the understanding of the petroleum prospectivity throughout the region by characterising the petroleum systems. 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 (Figure 1). The new data opens up this frontier part of the basin and enables better understanding of the geology, structure and petroleum prospectivity. A 2680 m stratigraphic drill hole, Waukarlycarly 1, was drilled in 2019 in partnership between GA and GSWA within the Waukarlycarly Embayment and provides new data and a greater understanding of a previously undrilled part of the basin. As part of the EFTF initiative over 70 wells were sampled and analysed for gas-in-fluid-inclusions, which provide critical data in understanding gas to source rock correlations.
