AGSO's SNOWS-3 survey in 1993 aimed to acquire at least 3000 km of deep seismic data in the offshore Canning Basin. The program was part of a multi-cruise effort to determine the regional structural framework and deep crustal structure of Australia's southern North West Shelf. Data were recorded using a 4800 m streamer and a 49 litre airgun source.
Use Cases
- Model regional structural frameworks based on deep crustal seismic lines.
- Assess hydrocarbon field development controls based on reactivated structures.
- Perform seismic correlations based on tie lines linking exploration wells.
- Analyze basin structure based on reflections down to 12 seconds two-way time.
Strengths
- At least 3000 km of planned seismic data acquisition.
- High-quality data acquisition parameters including a 4800 m streamer and 49 litre airgun source.
- Ties to principal exploration wells in the region and connects to previous surveys.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the specific offshore basin survey.
