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

The SNOWS-3 survey is a pre-cruise report from the Marine Geosciences and Petroleum Geology Program at the Australian Geological Survey Organisation (AGSO). It details plans for a 1993 deep-seismic acquisition program in the offshore Canning Basin, aiming to acquire at least 3000 km of data to determine the region's deep crustal structure and its control on hydrocarbon fields. The survey ties into previous SNOWS surveys and exploration wells.

Use Cases

• Modeling deep crustal structure based on seismic reflection data down to 12 seconds two-way time.
• Analyzing structural controls on hydrocarbon field development based on the survey's stated aims.
• Correlating regional seismic data using tie lines to exploration wells mentioned in the description.
• Studying basin reactivation effects on deposition based on the program's geological objectives.

Strengths

• Part of a multi-cruise program (SNOWS-1, SNOWS-2) with previous surveys acquiring over 4454 km of high-quality data.
• Specific recording parameters are detailed, including a 4800 m streamer and a 49-litre airgun source.
• Designed to tie principal exploration wells and link with adjacent basin surveys for regional context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a pre-cruise report; the actual seismic data files are not directly described.
