A multi-disciplinary study integrating structural architecture, sequence stratigraphy, palaeogeography and geochemistry has mapped the spatial and temporal distributions of Triassic source rocks on the central North West Shelf. The work highlights a new petroleum system in the Bedout Sub-basin and potential in the Beagle and Rowley sub-basins. This extended abstract was presented at the Australasian Exploration Geoscience Conference (AECG) in 2019.
Use Cases
- Modeling hydrocarbon generation potential based on mapped Triassic source rock distributions.
- Identifying new exploration targets based on lateral facies variations described between sub-basins.
- Correlating geochemical biomarker signatures to specific fluvial-deltaic mudstone sequences mentioned in the study.
Strengths
- Study integrates multiple geoscience disciplines including structural architecture, sequence stratigraphy, and geochemistry.
- Analysis covers three sub-basins (Bedout, Beagle, Rowley) on the central North West Shelf.
- Identifies a unique oil signature in the Bedout Sub-basin, suggesting a new petroleum system.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data files are in PDF and DOCX formats, which may require extraction for quantitative analysis.
