Deep Structure of the Gippsland and Bass Basins: Seismic Survey Data from 1988-1989

Project 9131.12 is an operational report for the first of two marine seismic surveys conducted in 1988-1989 by the R/V Rig Seismic. The survey collected approximately 1560 km of seismic reflection and refraction profiles to investigate the deep structure and petroleum potential of the Gippsland and Bass Basins off southeastern Australia. The data was collected by the Bureau of Mineral Resources (BMR) to assist the petroleum industry and support studies of basin evolution.

Use Cases

• Modeling basin evolution based on deep seismic transects described in the report.
• Analyzing petroleum migration and trap formation based on inferred extensional structures and transfer faults.
• Correlating regional seismic stratigraphy using the grid of profiles shot over the Boobyalla Sub-basin.
• Testing seismic equipment and navigation systems based on the methodology for equipment testing described.

Strengths

• Contains specific survey metrics: approximately 470 km of deep-water profiles and 1090 km of profiles over a sub-basin grid.
• Data collection methodology is detailed, including air-gun array sizes (52.4 litre and 26.7 litre) and record lengths (10-12 seconds).
• Report provides clear scientific objectives for improving definition of deep basin structure and evaluating evolution models.

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 1988-1989; freshness should be verified for contemporary applications.
