Triassic Petroleum Systems Mapping on Australia's North West Shelf

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

Use Cases

• Map Triassic source rock distribution using sequence stratigraphy and palaeogeography data.
• Correlate biomarker signatures like land-plant and algal signatures to specific fluvial-deltaic mudstone sequences (e.g., TR10-TR14).
• Analyze lateral facies variation from the Bedout Sub-basin into the Beagle and Rowley sub-basins.
• Assess hydrocarbon generation potential in the Upper Triassic using well-based geochemical analysis results.
• Compare carbonate platform environments in the Rowley Sub-basin with clastic-dominated fluvial-deltaic environments in the Beagle Sub-basin.

Strengths

• Multi-disciplinary study integrating structural architecture, sequence stratigraphy, palaeogeography, and geochemistry.
• Covers three distinct sub-basins: Bedout, Beagle, and Rowley.
• Identifies a new petroleum system on the North West Shelf with a unique mixed biomarker signature.

Limitations

• Dataset consists of conference abstract documents (DOCX/PDF), not structured tabular data.
• Specific sample sizes, row counts, and quantitative data metrics are unavailable.
• Geographic scope is limited to the central North West Shelf of Australia.
