The Huzzas 3D’s modern processing techniques (including FWI), allows excellent imaging and resolution in both shallow and deeper areas, which helps to address these key risks. The discovered accumulations are clearly imaged on the data and the geological horizons can be mapped into the proposed blocks where additional structural and stratigraphic traps can be identified.

The currently understood petroleum systems are of Upper Triassic, Middle–Upper Jurassic and Lower Cretaceous age within structural traps (tilted fault blocks and rollovers, anticlines and drapes, and horsts) and stratigraphic traps (pinch-outs, unconformity traps and transgressive sandstone packages at the base of the Locker Shale).
Gas-prone source rocks are from Triassic to Middle Jurassic fluvio-deltaic rocks of the Mungaroo and Brigadier formations, Murat Siltstone, and Athol and Legendre formations, and oil-prone source rocks are from the Upper Jurassic Dingo Claystone.
The identification of further subtle hydrocarbon trapping configurations is the main challenge with the area. Further prospectivity will probably be within low relief structural closures and stratigraphic traps. The identification of continuous top seal lithologies are also a key risk.
