L032 Haddon Downs Experimental Seismic Survey, South Australia, 1957

An experimental seismic survey was conducted at Haddon Downs, South Australia, during October and November 1957. The survey recorded two important refractors, one at about 2,700 feet and another at approximately 7,250 feet, which may be useful for semi-regional mapping. The work was conducted by Santos Ltd. within the Eromanga Sub-basin of the Great Artesian Basin.

Use Cases

• Map subsurface structures based on recorded seismic refractors with velocities of 10,250 ft/sec and 17,000 ft/sec.
• Interpret the thickness and composition of the Mesozoic and Palaeozoic sedimentary sections based on reflection and refraction data.
• Correlate minor subsurface structures with surface anticlines identified in preliminary reconnaissance.
• Analyze the effectiveness of large multiple geophone arrays and pattern shots for obtaining reflections in different terrain.

Strengths

• Survey recorded two distinct seismic refractors with specific velocities (10,250 ft/sec and 17,000 ft/sec) and depths.
• Description provides interpreted thicknesses for the sedimentary section, ranging from at least 8,000 to possibly 16,000 feet.
• Specific geographic and geological context is given: Haddon Downs, South Australia, within the Eromanga Sub-basin.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single survey in 1957; its freshness and compatibility with modern methods should be verified.
