Session 3. Oral Presentation for: New perspectives on the sequence stratigraphy of the Early-Middle Triassic of the Bedout Sub-basin

Presented on 27 May 2025: Session 3 The Bedout Sub-basin, part of the Roebuck Basin on Western Australia’s North West Shelf, has drawn interest since hydrocarbon discoveries at Roc, Dorado and Pavo. Despite these successes, the region remains underexplored. This study applies sequence stratigraphic analysis, well data and 3D seismic data to characterise the basin’s depositional history and hydrocarbon potential. A Wheeler diagram illustrates chronostratigraphic relationships, identifying key sequence stratigraphic play systems. Findings reveal a shallowing-upward trend from the Early to Middle Triassic, a new play system in Late Permian carbonates and highlight that the Archer reservoir sands are a series of low-stand deposits. These insights refine the Bedout Sub-basin’s stratigraphic framework and inform future exploration efforts. To access the Oral Presentation click the link below. To read the full paper click here
