Triassic Petroleum Systems Mapping on Australia's North West Shelf

Recent exploration success in the Greater Phoenix area has revived interest in Triassic petroleum systems on Australia's North West Shelf. This multi-disciplinary study integrates seismic mapping, sequence stratigraphy, and geochemical analyses to map source rock distributions across the Bedout, Beagle, and Rowley sub-basins. The extended abstract was presented at the Australasian Exploration Geoscience Conference in 2019 by the Australian Ocean Data Network.

Use Cases

• Mapping the spatial distribution of Triassic source rocks using seismic mapping and sequence stratigraphy data.
• Correlating hydrocarbon biomarker signatures from specific sequences like TR10–TR14 to identify new petroleum systems.
• Analyzing paleogeographic maps to distinguish between deltaic, marine carbonate, and volcanic environments across sub-basins.
• Evaluating hydrocarbon generation potential in Upper Triassic sediments using results from well-based geochemical analyses.
• Studying lateral facies variations from the Bedout Sub-basin into the adjacent Beagle and Rowley sub-basins.

Strengths

• Multi-disciplinary study integrating structural architecture, sequence stratigraphy, paleogeography, and geochemistry.
• Focus on a recently successful exploration area with revived industry interest.
• Analysis covers three distinct sub-basins (Bedout, Beagle, Rowley) for comparative study.

Limitations

• Dataset consists of conference abstract documents, lacking raw tabular data or column details.
• Sample size of geochemical analyses is unspecified and likely limited to specific well points.
• Temporal coverage is focused on the Triassic period, with no explicit date range for the underlying data.
