L032 Haddon Downs Experimental Seismic Survey, South Australia, 1957

L032 Haddon Downs experimental seismic survey was conducted in South Australia during October and November 1957. The survey, within the Eromanga Sub-basin, recorded two important seismic refractors and indicated a sedimentary section potentially 16,000 feet thick. Preliminary work by Santos Ltd. revealed large surface anticlines.

Use Cases

• Map subsurface geological structures based on identified seismic refractors at 2,700 and 7,250 feet.
• Analyze the thickness and composition of Mesozoic and Palaeozoic sedimentary sections.
• Correlate surface anticline structures with potential minor subsurface dips of less than 1 degree.
• Assess the utility of large geophone arrays and pattern shots for obtaining seismic reflections in varied terrain.

Strengths

• Description provides specific seismic velocities (10,250 ft/sec, 17,000 ft/sec) and depths for two key refractors.
• Survey details include geographic context (Eromanga Sub-basin), time period (Oct-Nov 1957), and involved company (Santos Ltd.).
• Sedimentary section thickness is estimated with specific bounds (8,000 to 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 may reflect geographic and temporal bias inherent to a single 1957 survey.
