Georgina Basin Geological Survey Data with HyLogging Mineralogy

Geoscience Australia's Onshore Energy Systems Group conducted a regional study of the southern Georgina Basin. The dataset includes reprocessed HyLogging mineralogical data from 25 wells, integrated with wireline logs, biostratigraphy, total organic carbon, and X-ray diffraction measurements. The work focuses on the Cambrian and Ordovician sediments in the Dulcie and Toko synclines.

Use Cases

• Characterize potential hydrocarbon source rocks based on integrated HyLogging, wireline log, and TOC data.
• Refine stratigraphic correlation models across basin depocentres using reprocessed mineralogical data and biostratigraphy.
• Identify 'hot shale' units in the Arthur Creek Formation based on spectral response patterns correlated with TOC.
• Test correlative models across basin depocentres using middle Cambrian carbon isotope excursion data.

Strengths

• Includes reprocessed HyLogging data from 25 wells, creating an internally-consistent basin-wide dataset.
• Integrates multiple data types: mineralogy (HyLogging), wireline logs, biostratigraphy, TOC, and XRD.
• Focuses on a defined geographical area: the 325,000 km2 Georgina Basin in western Queensland and the Northern Territory.

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 basin study area.
