Distribution of Triassic Reefs in the Northern Exmouth Plateau and Offshore Canning Basin

A 34-day research cruise in early 1990 aimed to acquire 2500 km of multichannel seismic profiles, 15 dredges, and up to 5 cores. The project, part of the BMR Offshore Sedimentary Basins Program, sought to map Triassic and Jurassic carbonate reefs to assess their petroleum potential on Australia's Northwest Shelf. The data is hosted by the Australian Ocean Data Network.

Use Cases

• Mapping the extent of Triassic/Jurassic carbonate facies based on seismic profiling and dredging techniques mentioned in the description.
• Assessing petroleum trap potential based on the identification of Late Triassic reef complexes described in the project.
• Evaluating source rock potential based on the analysis of lagoonal facies associated with the reefs.
• Correlating seismic character parameters to identify similar carbonate sequences in other basins, as suggested by the project's second phase.

Strengths

• Project involved acquisition of 2500 km of multichannel seismic profiles.
• Aims included 15 dredge samples and up to 5 cores for direct geological analysis.
• Focuses on a specific, novel exploration play (Triassic reefs) first identified in Australia.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic/temporal bias inherent to data_gov_au.
