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

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. This extended abstract was presented at the Australasian Exploration Geoscience Conference (AECG) in 2019 and is hosted by the Australian Ocean Data Network. The work highlights a new petroleum system in the Bedout Sub-basin and the potential for hydrocarbon generation in adjacent sub-basins.

Use Cases

• Mapping Triassic source rock distribution based on integrated structural and stratigraphic analysis.
• Identifying new petroleum systems based on unique biomarker signatures described in the study.
• Assessing hydrocarbon generation potential in underexplored sub-basins based on palaeogeographic reconstructions.
• Correlating geochemical well data with regional seismic mapping to evaluate reservoir prospects.

Strengths

• Study integrates multiple geoscience disciplines: structural architecture, sequence stratigraphy, palaeogeography, and geochemistry.
• Analysis covers three sub-basins: Bedout, Beagle, and Rowley, providing a regional perspective.
• 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, requiring extraction for computational analysis.
