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

Australia's North West Shelf, specifically the Bedout, Beagle, and Rowley sub-basins, is the focus of this geoscience study. The dataset likely contains findings from a multi-disciplinary study integrating structural architecture, sequence stratigraphy, palaeogeography, and geochemistry to map Triassic source rocks. This extended abstract was presented at the Australasian Exploration Geoscience Conference in 2019 and is provided by Geoscience Australia.

Use Cases

• Mapping the distribution and lateral facies variation of Triassic successions based on seismic mapping studies.
• Identifying potential hydrocarbon generation zones based on well-based geochemical analyses described in the study.
• Comparing petroleum systems across sub-basins based on the described palaeogeographic and biomarker signature variations.

Strengths

• Study integrates multiple disciplines: structural architecture, sequence stratigraphy, palaeogeography, and geochemistry.
• Focuses on a specific, recently successful exploration area: the Greater Phoenix area in the Bedout Sub-basin.
• Identifies a distinct petroleum system with a mixed land-plant and algal biomarker signature unique to the Bedout Sub-basin.

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 DOCX and PDF formats, which may require extraction for structured analysis.
