Cretaceous Stratigraphic Correlation Of Southern Australia Bight Basin

A 2026 stratigraphic interpretation correlates Cretaceous sedimentary rocks from Valanginian to Campanian age across onshore and offshore wells in Western and South Australia. The Australian Ocean Data Network compiled biostratigraphic and seismic data, identifying supersequences and organic-rich facies. The succession reaches over 357 meters thick in the Madura 1 well.

Use Cases

• Correlate supersequence boundaries (Bronze Whaler, Blue Whale-White Pointer, Tiger, Hammerhead) across wells using biostratigraphic data.
• Model depositional environment evolution from non-marine to marine conditions using interpreted facies and age data.
• Assess potential source rock distribution by analyzing organic-rich shale and marine affinity facies identified in wells.

Strengths

• Interpretation based on existing and recently commissioned biostratigraphic data.
• Correlates onshore wells with thicker offshore basinward sections using seismic data.

Limitations

• Specific row counts, column names, and sample data are unavailable.
• Data is presented in HTML and PDF formats, not structured for direct computational analysis.
• Geographic coverage is limited to wells along the southern Australian coast.
