Addressing exploration uncertainties in the southern Bonaparte Basin: enhanced stratigraph

Upper Permian to Lower Triassic sedimentary succession data from the southern Bonaparte Basin, Australia, informs petroleum exploration. The dataset includes palynological data and well re-interpretations to provide an updated stratigraphic scheme for the Petrel Sub-basin and Londonderry High. It addresses reservoir heterogeneity risks, particularly for the producing Blacktip gas field.

Use Cases

• Assessing reservoir effectiveness and heterogeneity risks based on post-drill analysis of well data.
• Calibrating chronostratigraphic models using reviewed palynological data and biostratigraphic schemes.
• Mapping the distribution of depositional environments for the Dombey, Tern, and Penguin formations.
• Evaluating the timing and duration of marine transgression across the Permian-Triassic boundary.

Strengths

• Integrates recent improvements in Australian biostratigraphic calibration, providing an up-to-date stratigraphic scheme.
• Focuses on a commercially significant region, referencing the Blacktip gas field in production since 2009.
• Synthesizes data from multiple wells and palynological reviews for a consistent interpretation.

Limitations

• Key metadata such as row count, specific column names, file size, and license are unavailable across all sources.
• The dataset appears to be an extended abstract or publication derivative, which may limit the raw data provided.
• Platform records show conflicting 'last updated' dates (2026-06-27 and 2026-04-04), creating uncertainty about versioning.
