An experimental seismic survey conducted in October and November 1957 at Haddon Downs, South Australia, within the Eromanga Sub-basin. The survey recorded two important refractors at depths of about 2,700 feet and 7,250 feet, suggesting a sedimentary section up to 16,000 feet thick. The data was likely collected by Santos Ltd. under an Oil Prospecting Licence.
Use Cases
- Map subsurface geological structures based on recorded seismic refractors.
- Analyze the thickness and composition of Mesozoic and Palaeozoic sediments based on velocity and depth interpretations.
- Correlate seismic data with surface anticline structures identified by preliminary reconnaissance.
- Assess regional and detailed subsurface structure using gravity work and seismic reflection data.
Strengths
- Survey recorded two distinct refractors with specific velocities (10,250 ft/sec and 17,000 ft/sec) and depths.
- Sedimentary section thickness is interpreted to be at least 8,000 feet and possibly 16,000 feet.
- Data collection employed large multiple geophone arrays and pattern shots to obtain good quality reflections.
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.
