A new stratigraphic interpretation of Cretaceous sedimentary rocks from petroleum wells and water bores along the southern Australian coast. The correlation integrates biostratigraphic and seismic data, identifying sedimentary sections from Valanginian to Campanian age. The record provides new information about potential source rocks in the Bight Basin.
Use Cases
- Correlating stratigraphic sequences based on biostratigraphic and seismic data mentioned in the description
- Analyzing depositional environment evolution from Early to Late Cretaceous conditions described
- Identifying potential hydrocarbon source rocks based on organic-rich shale facies identified
- Mapping the northern margin of the Bight Basin using well data from Western and South Australia
Strengths
- Interpretation based on existing and recently commissioned biostratigraphic data
- Correlation integrates seismic data from the continental shelf
- Maximum thickness of more than 357 m recorded in the Madura 1 well
- Identifies organic-rich non-marine and marine facies as potential source rocks
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect geographic/temporal bias inherent to data_gov_au
