Sediment Velocity Models for Capel and Faust Basins

Summer 2006/07 data from marine seismic survey GA302 over the Capel and Faust Basins on the Lord Howe Rise. The report describes velocity data from seismic reflection, refraction, and potential field surveys conducted by Geoscience Australia. It aims to improve sediment thickness estimation confidence for evaluating petroleum prospectivity in frontier basins.

Use Cases

• Model sediment thickness using stacking velocities from seismic reflection processing.
• Characterize upper crustal structure by integrating sonobuoy refraction data with seismic reflection profiles.
• Evaluate basin prospectivity by analyzing velocity-depth relationships within the sedimentary column.
• Calibrate regional seismic interpretations with high-quality velocity data from survey GA302.

Strengths

• Data acquired and processed to modern standards, providing high-quality inputs.
• Survey designed to address sparse previous data coverage over the frontier basins.

Limitations

• Primary data format is report-based (HTML/PDF), limiting direct machine-readability.
• Specific row counts, column details, and sample data are unavailable for quantitative analysis.
• Temporal coverage is limited to a single survey season in 2006/07.
