SNOWS-3: Deep Seismic Survey of the Offshore Canning Basin

A 1993 marine seismic survey planned to acquire at least 3000 km of high-quality data across the offshore Canning Basin. The program aimed to determine the deep crustal structure and regional framework of Australia's southern North West Shelf for hydrocarbon exploration. It was conducted by the Australian Geological Survey Organisation (AGSO) as part of a multi-cruise deep-seismic acquisition program.

Use Cases

• Modeling regional structural frameworks based on deep crustal seismic lines.
• Assessing hydrocarbon play controls based on the relationship between deep structure and field development.
• Correlating regional seismic stratigraphy based on tie lines linking exploration wells.

Strengths

• Planned acquisition of at least 3000 km of seismic data, with a program allowance for up to 3500 km.
• Data tied to principal exploration wells in the region, facilitating calibration.
• Survey parameters included a 16-second record length and 2 ms sample interval, suggesting high temporal resolution for deep imaging.

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.
