Southern Bonaparte Basin Stratigraphic Analysis for Upper Permian Gas Plays

The southern Bonaparte Basin in Australia contains an upper Permian to Lower Triassic sedimentary succession hosting gas accumulations like the Blacktip field, in production since 2009. This dataset is an extended abstract from the 2022 APPEA Conference, presenting a review of palynological data and well re-interpretation to improve chronostratigraphic calibration. The work aims to address reservoir heterogeneity risks by providing an updated stratigraphic scheme for the Petrel Sub-basin and Londonderry High.

Use Cases

• Modeling reservoir heterogeneity based on described lithofacies transitions from carbonate to siliciclastic formations.
• Calibrating chronostratigraphic timelines based on the reviewed late Permian and Early Triassic biostratigraphic schemes.
• Assessing gas exploration risks based on the post-drill analysis of well data and reservoir effectiveness findings.
• Mapping depositional environment distribution based on the improved stratigraphic scheme for the Petrel Sub-basin.

Strengths

• Focuses on a producing gas field (Blacktip) with operational history since 2009.
• Incorporates recent improvements in chronostratigraphic calibration for the late Permian and Early Triassic.
• Analysis covers specific geographic sub-regions: the Petrel Sub-basin and Londonderry High.

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.
• Row count is unknown, which may limit suitability assessment.
