Triassic petroleum systems on the central North West Shelf – Learnings from the Greater Ph

Geoscience Australia Data presents a multi-disciplinary study integrating structural architecture, sequence stratigraphy, palaeogeography, and geochemistry for the central North West Shelf. The study maps the spatial and temporal distributions of Triassic source rocks across the Bedout, Beagle, and Rowley sub-basins, identifying a new petroleum system. This extended abstract was presented at the Australasian Exploration Geoscience Conference in 2019.

Use Cases

• Model hydrocarbon generation potential based on mapped Triassic source rock distributions.
• Analyze paleogeographic evolution based on described deltaic, marine, and carbonate environments.
• Correlate geochemical biomarker signatures to specific fluvial-deltaic mudstone sequences.
• Assess structural architecture and sequence stratigraphy for exploration targeting.

Strengths

• Integrates multiple geological disciplines: structural architecture, sequence stratigraphy, palaeogeography, and geochemistry.
• Focuses on a region with recent exploration success, including the Phoenix South 1 discovery.
• Covers three sub-basins: Bedout, Beagle, and Rowley, providing comparative analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented as an extended abstract (PDF/DOCX), not raw structured data files.
