Haddon Downs Experimental Seismic Survey Data

Two seismic refractors were recorded at depths of 2,700 and 7,250 feet during this 1957 survey. The data reveals a sedimentary section up to 16,000 feet thick within the Eromanga Sub-basin. The survey was conducted by Santos Ltd. and is managed by the Australian Ocean Data Network.

Use Cases

• Map regional subsurface structure using recorded refractor velocities of 10,250 ft/sec and 17,000 ft/sec.
• Correlate seismic refractor depths with surface anticline structures identified in preliminary reconnaissance.
• Estimate thickness of the Mesozoic section by analyzing refraction traverse depths of 7,250 feet and reflection traverse depths of 8,600 feet.
• Investigate the presence of dense limestone near the top of the Palaeozoic section indicated by the high 17,000 ft/sec velocity refractor.

Strengths

• Survey recorded two distinct seismic refractors at specified depths and velocities.
• Data provides interpreted sediment thickness estimates ranging from 8,000 to 16,000 feet.
• Survey area is geologically defined within the Eromanga Sub-basin of the Great Artesian Basin.

Limitations

• Data is from a single, historical 1957 survey with no modern updates.
• Specific row count, column details, and sample data are unavailable for review.
• Geographic coverage is limited to the Haddon Downs area in South Australia.
