Georgina Basin Geoscience Data: HyLogging, TOC, and Biostratigraphy from 25 Wells

Geoscience Australia's synopsis presents results from a regional study of the southern Georgina Basin. The data package includes reprocessed HyLogging data from 25 wells, integrated with total organic carbon (TOC), X-ray diffraction (XRD), biostratigraphy, and wireline log data. The study focuses on characterizing potential hydrocarbon source rocks within the Cambrian and Ordovician sediments.

Use Cases

• Correlating stratigraphic units across depocentres based on integrated HyLogging and biostratigraphic data.
• Identifying potential hydrocarbon source rock units using spectral response patterns from HyLogging data correlated with TOC.
• Testing age correlation models across the Dulcie and Toko synclines using middle Cambrian carbon isotope excursions.

Strengths

• Internally-consistent, basin-wide dataset created by reprocessing HyLogging data from 25 wells using a common set of mineral scalars.
• Multidisciplinary integration of HyLogging, wireline log, biostratigraphic, TOC, and XRD data for refined stratigraphic correlation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific southern depocentres of the Georgina Basin.
