Hyperspectral Logging Data from 13 Wells in Southern Georgina Basin

2026-03-25 updated dataset contains hyperspectral logging data from 13 petroleum, mineral, and stratigraphic wells in the southern Georgina Basin, Australia. The data characterizes middle Cambrian marine sediments, focusing on source rock units like the Thorntonia Limestone and Arthur Creek Formation. It maps mineralogy and spectral properties to assess hydrocarbon prospectivity.

Use Cases

• Correlate HyLogger mineralogy data with gamma log intensity peaks to identify organic-rich shale units for petroleum exploration.
• Analyze Short-Wave Infrared reflectance and spectral contrast alongside mineralogy to differentiate sedimentological characteristics within the Arthur Creek Formation.
• Map spatial heterogeneity of quartz, carbonate, and white-mica contents across the Dulcie and Toko synclines to understand formation boundaries.
• Evaluate associations between hyperspectral data and measured total organic carbon contents to characterize key source rock units.

Strengths

• Data sourced from 13 wells, providing multi-well coverage for the study area.
• Integrates hyperspectral logging with wireline log and X-ray diffraction data for multi-method validation.
• Focuses on key hydrocarbon source rock units (Thorntonia Limestone, Arthur Creek Formation) with detailed mineralogical characterization.

Limitations

• Sample data and column structure are unavailable, hindering immediate technical analysis.
• The dataset is described via HTML, which may not be a readily analyzable tabular format for ML.
• Geographic scope is limited to the southern Georgina Basin in northern Australia.
