Southern Bonaparte Basin Stratigraphic Analysis for Upper Permian Plays

The southern Bonaparte Basin in Australia contains an upper Permian to Lower Triassic sedimentary succession with marginal marine deposits and gas accumulations like the Blacktip field. This dataset provides a re-interpreted stratigraphic scheme based on updated palynological data and well analysis from the Petrel Sub-basin and Londonderry High. The work was presented at the 2022 APPEA Conference by researchers including R. Owens and A. Kelman.

Use Cases

• Correlate lithofacies transitions from the Dombey Formation to Tern and Penguin formations using the updated stratigraphic scheme.
• Assess reservoir heterogeneity and effectiveness risks by analyzing post-drill well data from the study area.
• Model depositional environment timing and distribution across the Petrel Sub-basin using chronostratigraphically calibrated palynological data.

Strengths

• Analysis focuses on a producing gas field (Blacktip) with data since 2009.
• Integrates recent improvements in Australian biostratigraphic schemes for the late Permian and Early Triassic.

Limitations

• Core data like well logs, sample counts, and row/column specifics are unavailable.
• The dataset is an extended conference abstract, not a primary data release.
• Geographic scope is limited to the southern Bonaparte Basin.
