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. The research maps the spatial and temporal distributions of Triassic source rocks on the central North West Shelf, focusing on the Greater Phoenix area in the Bedout Sub-basin. This extended abstract was presented at the Australasian Exploration Geoscience Conference in 2019.

Use Cases

• Identify hydrocarbon generation potential based on mapped Triassic source rock distributions.
• Compare petroleum systems based on biomarker signatures and palaeogeographic environments described.
• Guide exploration targeting based on the structural architecture and sequence stratigraphy framework.
• Analyze lateral facies variation based on the mapping of the Triassic succession from the Bedout into adjacent sub-basins.

Strengths

• Integrates multiple geoscience disciplines: structural architecture, sequence stratigraphy, palaeogeography, and geochemistry.
• Identifies a new petroleum system on the North West Shelf based on a unique mixed biomarker signature.
• Maps spatial and temporal distributions across three sub-basins: Bedout, Beagle, and Rowley.

Limitations

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