Southern Bonaparte Basin Upper Permian Stratigraphic Analysis and Post-Drill Data

An extended abstract from the 2022 APPEA Conference presents a review of stratigraphic and well data from the southern Bonaparte Basin, Australia. The work focuses on the upper Permian to Lower Triassic sedimentary succession, which hosts gas accumulations like the Blacktip field. The analysis uses updated biostratigraphic schemes to improve understanding of depositional environments in the Petrel Sub-basin and Londonderry High.

Use Cases

• Refining chronostratigraphic models based on the reviewed palynological and biostratigraphic data.
• Assessing reservoir heterogeneity and effectiveness risks for gas exploration, as highlighted in the post-drill analysis.
• Mapping the distribution of depositional environments for the Dombey, Tern, and Penguin formations.
• Calibrating regional geological models using the improved stratigraphic scheme for the Permian–Triassic boundary.

Strengths

• Analysis is informed by recent improvements in Australian biostratigraphic schemes for the late Permian and Early Triassic.
• Focuses on a known hydrocarbon province with producing fields, such as the Blacktip gas field in production since 2009.
• Provides a re-interpretation and infill sampling of well data for better stratigraphic resolution.

Limitations

• Dataset consists of conference abstract documents (PDF, HTML); the underlying raw well data is not directly provided.
• Column-level documentation and sample data are unavailable, limiting immediate analysis.
• The temporal and spatial coverage of the source well data is not explicitly detailed.
