Hyperspectral Logging of Cambrian Marine Sediments in the Southern Georgina Basin

Hyperspectral logging data from 13 wells in the southern Georgina Basin, northern Australia, evaluated by the Australian Ocean Data Network. The data characterizes middle Cambrian marine sediments, including key source rock units like the Thorntonia Limestone and Arthur Creek Formation. Interpretation alongside wireline logs supports differentiation of organic-rich shale units based on mineralogy and spectral properties.

Use Cases

• Characterizing mineralogy of prospective hydrocarbon formations based on hyperspectral and X-ray diffraction data mentioned in the description.
• Mapping organic-rich shale units based on spectral properties like SWIR reflectance and spectral contrast described.
• Correlating hyperspectral mineralogy with geophysical log data, such as gamma log intensity, to understand sedimentological characteristics.
• Differentiating source rock units within sedimentary basins based on integrated spectral and biostratigraphic data.

Strengths

• Data covers 13 wells, providing multiple sampling points across the study area.
• Integrates multiple data types: hyperspectral logging, X-ray diffraction, and wireline log data.
• Focuses on key, defined geological units: the middle Cambrian Narpa Group, Thorntonia Limestone, and Arthur Creek Formation.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
