Late Permian–Early Triassic Depositional History in the Southern Bonaparte Basin

An extended abstract from the 2021 APPEA Conference details the sedimentary succession hosting the Blacktip gas field, in production since 2009. The study focuses on the timing and environment of formations across the Permian–Triassic boundary in the Petrel Sub-basin and Londonderry High. This work, published in The APPEA Journal, translates depositional history into a chronostratigraphic framework for predicting petroleum system elements.

Use Cases

• Modeling basin evolution and marine transgression based on described lithofacies changes from carbonate to siliciclastic formations.
• Correlating petroleum system elements like source and reservoir rocks using the provided chronostratigraphic framework.
• Assessing gas resource potential in the Petrel Sub-basin based on the study of identified accumulations like the Blacktip field.

Strengths

• Focuses on a producing hydrocarbon region, with the Blacktip gas field noted as in production since 2009.
• Provides a interpreted depositional history spanning the significant End Permian Extinction event and floral/faunal recovery.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
