L032 Haddon Downs Experimental Seismic Survey, South Australia 1957

An experimental seismic survey conducted in 1957 within the Eromanga Sub-basin of the Great Artesian Basin. The data reveals at least 8,000 feet and possibly up to 16,000 feet of sedimentary section, with two important seismic refractors recorded at depths of approximately 2,700 and 7,250 feet. The survey was conducted by Santos Ltd. and contributed to preliminary mapping of subsurface structures.

Use Cases

• Map subsurface geological structures based on identified seismic refractors and reflection data.
• Correlate surface anticlines with minor subsurface dips of less than 1 degree as mentioned in the description.
• Estimate the thickness and composition of Mesozoic and Palaeozoic sedimentary sections from the reported depth interpretations.
• Analyze the utility of large geophone arrays and pattern shots for obtaining reflections in different terrain types.

Strengths

• Survey identified two distinct seismic refractors with specific velocities (10,250 ft/sec and 17,000 ft/sec) and approximate depths.
• Provides interpreted depths for the base of the Mesozoic section at two locations (7,250 feet and 8,600 feet).
• Describes a sedimentary section thickness ranging from at least 8,000 feet to possibly 16,000 feet.

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 experimental survey in 1957; modern techniques may provide higher resolution.
