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

The southern Georgina Basin in northern Australia is the focus of this dataset. Hyperspectral logging data from HyLoggerTM instruments were evaluated from 13 petroleum, mineral, and stratigraphic wells. The data characterize key hydrocarbon source rock units in terms of mineralogy and spectral properties.

Use Cases

• Characterizing mineralogy of prospective source rock units based on hyperspectral data.
• Differentiating organic-rich shale units based on spectral properties and wireline log correlations.
• Mapping spatial heterogeneity of sedimentological and diagenetic features within a basin.
• Identifying associations between gamma log intensity, organic carbon content, and mineral composition.

Strengths

• Data covers 13 wells in a defined geological study area.
• Integrates hyperspectral data with wireline log data and X-ray diffraction for validation.
• Focuses on key, identified source rock units (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.
