Late Permian–Early Triassic Sedimentary Succession in the Southern Bonaparte Basin

Geoscience Australia Data provides a study of the upper Permian to Lower Triassic sedimentary succession in the southern Bonaparte Basin, published in The APPEA Journal on 2 July 2021. The data focuses on the Petrel Sub-basin and Londonderry High, interpreting marginal marine facies across formations like Dombey, Tern, Penguin, and Mairmull. This chronostratigraphic framework aims to predict petroleum system elements for gas resources including the Blacktip field.

Use Cases

• Modeling basin depositional history based on interpreted marginal marine facies and marine transgression events.
• Correlating petroleum system elements based on the chronostratigraphic framework for the Petrel Sub-basin and Londonderry High.
• Assessing gas resource potential based on the study of formations hosting accumulations like the Blacktip field.
• Analyzing lithofacies changes from carbonate to siliciclastic dominance across the Permian–Triassic boundary.

Strengths

• Focuses on a specific, economically significant region: the southern Bonaparte Basin, including the Petrel Sub-basin and Londonderry High.
• Links stratigraphic analysis to a known producing asset: the Blacktip gas field, in production since 2009.
• Provides a temporal framework spanning a major geological boundary: the Permian–Triassic stratigraphic boundary and End Permian Extinction event.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
