Southern Bonaparte Basin Upper Permian Stratigraphic Analysis and Well Data

An extended abstract from the 2022 APPEA Conference presents a review of palynological data and re-interpretation of well data from the southern Bonaparte Basin. The work by Owens et al. provides an updated stratigraphic scheme for the upper Permian to Lower Triassic sedimentary succession, which hosts gas accumulations like the Blacktip field. The analysis aims to address reservoir heterogeneity, identified as a key exploration risk in the Petrel Sub-basin and Londonderry High.

Use Cases

• Modeling reservoir heterogeneity based on described lithofacies transitions from carbonate to siliciclastic formations.
• Calibrating chronostratigraphic frameworks using the reviewed palynological data and biostratigraphic schemes.
• Assessing exploration risk for gas plays by analyzing post-drill well data from the study area.

Strengths

• Analysis is informed by recent improvements in Australian biostratigraphic schemes for the late Permian and Early Triassic.
• Focuses on a specific, economically significant region containing the producing Blacktip gas field.

Limitations

• The dataset consists of conference abstract documents (PDF/HTML); underlying raw well data and column definitions are not provided.
• Row count and data scale are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
