Bight Basin Cretaceous Stratigraphic Correlation for Southern Australia

Southern Australia's Bight Basin contains a new stratigraphic interpretation of Cretaceous sedimentary rocks from petroleum wells and water bores. The record, published by Geoscience Australia, correlates onshore and offshore sections using biostratigraphic and seismic data. It identifies organic-rich shales from the Valanginian to Campanian stages, with sections reaching over 357 meters thick in the Madura 1 well.

Use Cases

• Modeling basin evolution based on sequence stratigraphic framework
• Correlating depositional environments based on biostratigraphic and seismic data
• Identifying potential hydrocarbon source rocks based on described organic-rich facies
• Analyzing paleoenvironmental changes from non-marine to marine conditions

Strengths

• Interpretation based on multiple data sources including biostratigraphy and seismic data
• Identifies specific supersequences (Bronze Whaler, Blue Whale-White Pointer, Tiger, Hammerhead)
• Maximum thickness of over 357 meters documented in the Madura 1 well
• Covers a defined temporal range from Valanginian to Campanian stages

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is presented in PDF/HTML formats, which may require extraction for analysis
