Triassic Petroleum Systems on Australia's North West Shelf from Seismic Mapping

Australia's North West Shelf, specifically the Bedout, Beagle, and Rowley sub-basins, is the focus of this geoscientific study. The dataset integrates structural architecture, sequence stratigraphy, palaeogeography, and geochemistry to map Triassic source rock distributions. This extended abstract was presented at the Australasian Exploration Geoscience Conference in 2019.

Use Cases

• Model hydrocarbon generation potential based on mapped Triassic source rock distributions.
• Analyze paleogeographic evolution based on described deltaic, marine, and carbonate environments.
• Correlate oil biomarker signatures to specific fluvial-deltaic mudstone sequences mentioned in the description.
• Map structural architecture and lateral facies variation across sub-basins for exploration targeting.

Strengths

• Integrates multiple geoscientific disciplines: structural architecture, sequence stratigraphy, palaeogeography, and geochemistry.
• Identifies a distinct petroleum system with a mixed land-plant and algal biomarker signature unique to the Bedout Sub-basin.
• 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.
• Data may reflect geographic bias inherent to data_gov_au, focusing on a specific region of the North West Shelf.
