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

An extended abstract from the Australasian Exploration Geoscience Conference 2019 presents findings from a multi-disciplinary study integrating structural architecture, sequence stratigraphy, palaeogeography, and geochemistry. The study maps the spatial and temporal distributions of Triassic source rocks on the central North West Shelf of Australia, focusing on the Greater Phoenix area across the Bedout, Beagle, and Rowley sub-basins. The abstract was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Identify hydrocarbon generation potential based on mapped Triassic source rock distributions.
• Analyze basin evolution based on integrated structural architecture and sequence stratigraphy.
• Compare petroleum systems based on biomarker signatures and palaeogeographic maps described in the study.
• Assess exploration targets based on the lateral facies variation of the Triassic succession.

Strengths

• Study integrates multiple geoscience disciplines: structural architecture, sequence stratigraphy, palaeogeography, and geochemistry.
• Focuses on a specific, recently successful exploration area (Greater Phoenix) and extends analysis to adjacent underexplored sub-basins.
• Identifies a unique, locally sourced petroleum system with a mixed land-plant and algal biomarker signature.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
