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

A 1955 seismic velocity survey conducted by the Bureau of Mineral Resources in the Associated Freney Oilfields Nerrima No. 1 Bore. The survey measured average velocities ranging from 8,000 to 12,200 feet per second over the total depth of the borehole, located on the Nerrima Dome in Western Australia's Fitzroy Basin.

Use Cases

• Modeling subsurface rock properties based on measured seismic velocities.
• Analyzing historical geophysical survey techniques based on the 1955 date and methodology.
• Correlating formation breaks with seismic velocity changes based on the description of recognizing true formation breaks.
• Studying velocity gradients in sedimentary basins based on the reported range from 8,000 to 12,200 ft/sec.

Strengths

• Provides specific average velocity measurements from 8,000 ft/sec to 12,200 ft/sec.
• Includes concrete temporal and geographic context: survey date of 10 August 1955 and location on the Nerrima Dome, Fitzroy Basin, Western Australia.
• Describes operational context, such as cable breaks for the shallow part of the hole.

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/temporal/source bias inherent to data_gov_au.
