Session 3. Oral Presentation for: The Walyering discovery and revisiting the Jurassic hydrocarbon potential of the northern Perth Basin

Presented on 27 May 2025: Session 3 The success of the Walyering field underscores the potential for commercial discoveries within the overlooked Jurassic sequence of the northern Perth Basin. The 3000–4000 m depth interval within this sequence continues to demonstrate permeability conducive to commercial flow rates, benefiting from proximity to the major hydrocarbon source depocentre of the Dandaragan Trough. Following exploration success at Walyering-5 in 2021, there has been renewed interest in the Cattamarra Coal Measures, leading to acquisition of multiple new 3D seismic surveys and the reprocessing of existing 2D data. This paper revisits the highly prospective Jurassic fairway trend from Ocean Hill to Walyering, providing valuable insights that will guide Strike Energy’s near-term exploration program. The Jurassic wells offer significant advantages over deeper Permian wells, including shallower drilling depths (3000+ m versus 4000+ m), reduced well costs (~>AU$10,000,000), and minimal gas impurities (typically less than 1% CO2). Additionally, the presence of liquid hydrocarbon ranging >8 bbls/MMscf and the low complexity of required facilities enable a swift transition from final investment decision to first gas, potentially within 12 months. This paper highlights the strategic importance of the Jurassic sequence in the northern Perth Basin and its role in future exploration efforts, driven by the successes at Walyering and the advantages of developing these Jurassic targets.
