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

A 2019 study presented at the Australasian Exploration Geoscience Conference integrates structural architecture, sequence stratigraphy, palaeogeography, and geochemistry. It maps the spatial and temporal distributions of Triassic source rocks in the central North West Shelf, including the Bedout, Beagle, and Rowley sub-basins. The data was contributed by the Australian Ocean Data Network.

Use Cases

• Mapping hydrocarbon source rock distribution based on integrated geochemical and seismic studies.
• Analyzing palaeogeographic evolution of deltaic and carbonate systems during the Triassic period.
• Identifying new petroleum systems based on mixed land-plant and algal biomarker signatures.
• Correlating lateral facies variations across adjacent sub-basins for exploration targeting.

Strengths

• Study integrates multiple geoscience disciplines: structural architecture, sequence stratigraphy, palaeogeography, and geochemistry.
• Focuses on a specific, recently successful exploration area (Greater Phoenix area, Bedout Sub-basin).
• Maps spatial distributions across three sub-basins: Bedout, Beagle, and Rowley.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the specific study area on the North West Shelf.
