A pre-cruise report for the SNOWS-3 survey, part of a multi-cruise program acquiring deep-seismic data on Australia's southern North West Shelf. The Bureau of Mineral Resources (BMR/AGSO) initiated the program in mid-1991 to provide a regional framework for hydrocarbon exploration. The SNOWS-3 survey, planned for the second half of 1993, aimed to acquire at least 3000 km of seismic data in the offshore Canning Basin.
Use Cases
- Modeling regional crustal structure based on deep seismic reflection data.
- Analyzing the control of deep structures on hydrocarbon field development.
- Correlating seismic data across exploration wells using high-quality tie lines.
- Mapping boundaries between major structural elements of the southern North West Shelf.
Strengths
- Program aims to acquire at least 3000 km of seismic data, with a capacity for up to 3500 km.
- Previous surveys SNOWS-1 and SNOWS-2 recorded 1654 km and over 2800 km of high-quality data respectively.
- Data from prior surveys show basin structure down to depths of at least 10-12 seconds two-way time.
- Survey parameters include a 4800 m streamer and a 49 litre airgun source, suggesting high-resolution acquisition.
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.
- Row count is unknown, which may limit suitability assessment.
