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

Deep seismic reflection data from the SNOWS-3 survey, a marine geoscience program conducted in 1993. The survey was designed to acquire at least 3000 km of seismic lines to determine the deep crustal structure of the southern North West Shelf's offshore Canning Basin. The data were collected by the Australian Geological Survey Organisation (AGSO) to provide a regional framework for hydrocarbon exploration.

Use Cases

• Model regional tectonic frameworks based on deep crustal structure data.
• Assess hydrocarbon play potential based on the control of deep structures on deposition.
• Correlate regional seismic stratigraphy using tie lines to exploration wells.

Strengths

• Planned acquisition of at least 3000 km of high-quality seismic data.
• Data tied to principal exploration wells in the region for calibration.
• Recording parameters included a 16-second record length for deep imaging.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified; the pre-cruise report describes plans from 1993.
