Capricorn and Northern Tasman Basins: Marine Seismic Survey Data from 1989

Southeast Queensland offshore basins were surveyed in December 1989 by the Bureau of Mineral Resources. The research cruise acquired 2900 km of multi-channel seismic reflection data, along with sonobuoy refraction, gravity, magnetic, and bathymetric data. It was the first such survey in the region since 1974 and included ties to the Aquarius-1 and Capricorn-1A wells.

Use Cases

• Modeling basin structure and evolution based on seismic reflection data.
• Assessing petroleum resource potential based on stratigraphic interpretations.
• Analyzing post-rift sediment thickness based on the described 1.5 seconds two-way time interval.
• Correlating regional geology by tying seismic data to the Aquarius-1 and Capricorn-1A wells.

Strengths

• Includes 2900 km of multi-channel seismic reflection data.
• Integrates multiple geophysical data types: seismic, sonobuoy refraction, gravity, magnetic, and bathymetry.
• Provides ties to key regional wells (Aquarius-1 and Capricorn-1A).
• Was the first major seismic survey in the region since 1974.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single survey in 1989; temporal coverage is limited.
