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 data, provided by Geoscience Australia, reveals a sedimentary section potentially 16,000 feet thick and identifies two key seismic refractors at depths of 2,700 and 7,250 feet. This work was performed by Santos Ltd. to investigate subsurface structures for petroleum exploration within the Eromanga Sub-basin.

Use Cases

• Map subsurface geological structures based on identified seismic refractors and reflection data.
• Model the thickness and composition of Mesozoic and Palaeozoic sedimentary sections based on described depths and velocities.
• Correlate surface anticline structures with minor subsurface dips mentioned in the description.
• Analyze seismic velocity data (10,250 ft/sec, 17,000 ft/sec) to infer rock properties like the presence of dense limestone.

Strengths

• Identifies two specific seismic refractors with recorded velocities (10,250 ft/sec and 17,000 ft/sec) and approximate depths.
• Describes a sedimentary section with a measured thickness of at least 8,000 feet and a possible maximum of 16,000 feet.
• Provides specific geographic and geological context, placing the survey within the Eromanga Sub-basin of the Great Artesian Basin.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific file structure are unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to a single survey conducted in 1957.
