Nerrima No. 1 Bore Seismic Velocity Survey, Fitzroy Basin 1955

Western Australia's Fitzroy Basin hosts a seismic velocity survey from the Nerrima No. 1 borehole. The Bureau of Mineral Resources conducted the survey on 10 August 1955, measuring average velocities from 8,000 to 12,200 feet per second. Some cable breaks were reported for shallow depths, but formation breaks were generally identifiable.

Use Cases

• Calibrating seismic interpretations based on measured velocity-depth profiles.
• Modeling subsurface rock properties in the Fitzroy Basin based on formation break data.
• Analyzing historical geophysical survey techniques based on the 1955 methodology and reported cable issues.

Strengths

• Specific velocity measurements ranging from 8,000 to 12,200 feet per second are provided.
• Survey date (10 August 1955) and location (Nerrima Dome, Fitzroy Basin) are explicitly stated.
• The conducting organization, the Bureau of Mineral Resources, is named.

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 temporal and methodological bias inherent to a 1955 survey.
