Nerrima No. 1 Bore: Seismic Velocity Survey 1955

A 1955 survey measured seismic velocities from 8,000 ft/sec near the top to 12,200 ft/sec at total depth in the Associated Freney Oilfields Nerrima No. 1 Bore. The Bureau of Mineral Resources conducted the work on the Nerrima Dome in Western Australia's Fitzroy Basin, noting cable breaks in shallow sections. This dataset provides a historical record of formation velocities for a specific exploratory well.

Use Cases

• Calibrating seismic interpretations based on measured formation velocities from a specific borehole.
• Analyzing historical geophysical survey methods and data quality from the 1950s.
• Modeling subsurface rock properties in the Nerrima Dome region using velocity-depth profiles.

Strengths

• Provides specific, measured velocity values ranging from 8,000 to 12,200 feet per second.
• Contains detailed provenance: survey conducted by the Bureau of Mineral Resources on August 10, 1955.
• Describes a specific geographic and geological context (Nerrima Dome, Fitzroy Basin, Western Australia).

Limitations

• Column names and data structure are unknown, limiting immediate analysis.
• Metadata on row count, file size, and license is absent from all sources.
• The dataset's primary format is PDF/HTML, which may require extraction for computational use.
