Georgina Basin Geological Data with HyLogging from 25 Wells

A synopsis of a regional study on the southern Georgina Basin, a 325,000 km2 sedimentary basin in Australia. The data package includes reprocessed HyLogging mineralogical data from 25 wells, integrated with wireline logs, biostratigraphy, total organic carbon, and X-ray diffraction measurements. The work was conducted by Geoscience Australia's Onshore Energy Systems Group, with a synopsis last updated in 2026.

Use Cases

• Characterizing potential hydrocarbon source rocks based on spectral response and total organic carbon correlations.
• Refining stratigraphic correlation models across depocentres using integrated HyLogging, wireline, and biostratigraphic data.
• Mapping mineralogical variations within formations like the Arthur Creek Formation using internally-consistent HyLogging data.
• Testing correlative models across the basin using middle Cambrian carbon isotope excursion data.

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, total organic carbon, and X-ray diffraction data.
• Focus on a defined 325,000 km2 geological region with identified depocentres and formations.

Limitations

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