Hyperspectral Logging of Cambrian Marine Sediments in the Georgina Basin, Australia

13 wells in the southern Georgina Basin were evaluated using HyLoggerTM hyperspectral instruments. The data characterize middle Cambrian source rock units, linking mineralogy and spectral properties to organic content and gamma log intensity. Geoscience Australia Data published this study to demonstrate how hyperspectral logging improves understanding of prospective hydrocarbon formations.

Use Cases

• Predicting total organic carbon content based on associations between gamma log intensity, SWIR reflectance, and spectral contrast.
• Differentiating organic-rich shale units within the Arthur Creek Formation using combined hyperspectral and wireline log data.
• Mapping spatial heterogeneity of mineralogy (e.g., quartz, carbonate, white-mica) in prospective source rock formations.
• Correlating formation boundaries with distinctive changes in mineralogy identified by spectral and X-ray diffraction data.

Strengths

• Data covers 13 petroleum, mineral, and stratigraphic wells, providing multiple perspectives on the basin.
• Integrates hyperspectral logging with wireline log data, supporting multi-modal analysis.
• Study demonstrates specific associations between gamma log peaks, decreased carbonate, and increased white micas and quartz.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Data freshness should be verified despite the listed update date of 2026-04-20.
