Hyperspectral Well Logs for Cambrian Hydrocarbon Source Rocks in Georgina Basin

Hyperspectral logging data from 13 wells in the southern Georgina Basin, Australia, characterize middle Cambrian marine sediments. The dataset, provided by the Australian Ocean Data Network, includes mineralogy and spectral properties to evaluate petroleum source rocks. It was last updated in April 2026.

Use Cases

• Correlate gamma log intensity peaks with specific mineralogical compositions like white mica and quartz content.
• Differentiate organic-rich shale units within the Arthur Creek Formation using combined hyperspectral and wireline log data.
• Map spatial heterogeneity of source rocks by analyzing Short-Wave Infrared reflectance and spectral contrast variations.
• Assess hydrocarbon prospectivity by identifying associations between total organic carbon content and HyLogger mineralogy data.

Strengths

• Data from 13 distinct wells provides multiple sampling points.
• Combines hyperspectral, mineralogical, and geophysical wireline log data for cross-validation.
• Focuses on key middle Cambrian source rock units with known hydrocarbon shows.

Limitations

• Unknown total row count and sample density per well.
• Geographic scope is limited to the southern Georgina Basin in Australia.
• Data format is HTML, which may require parsing to extract structured data.
