Marine Seismic Survey of the Capricorn and Northern Tasman Basins, 1989

The Bureau of Mineral Resources conducted a major marine multi-channel seismic reflection survey off southeast Queensland in December 1989. The research cruise acquired 2900 km of seismic data over the Capricorn Basin and northern Tasman Basin margins, tying to the Aquarius-1 and Capricorn-1A wells. It was the first such survey in the region since 1974 and also collected sonobuoy refraction, gravity, magnetic, and bathymetric data.

Use Cases

• Modeling basin structure and stratigraphy based on seismic reflection data.
• Assessing petroleum resource potential based on syn-rift and post-rift sediment sequences.
• Correlating regional geology using ties to deep offshore wells mentioned in the description.
• Analyzing geophysical properties using the collected gravity, magnetic, and bathymetric data.

Strengths

• Includes 2900 km of seismic data, providing substantial spatial coverage.
• Integrates multiple data types: seismic reflection, sonobuoy refraction, gravity, magnetic, and bathymetry.
• Provides ties to the only deep offshore wells in the region, Aquarius-1 and Capricorn-1A.

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.
• Data is from a 1989 survey; freshness should be verified for contemporary applications.
