Georgina Basin Geological Data with HyLogging and Biostratigraphy

The Georgina Basin covers 325,000 km² of western Queensland and the Northern Territory. Geoscience Australia's Onshore Energy Systems Group presents a synopsis of a multidisciplinary regional study, integrating reprocessed HyLogging data from 25 wells with wireline logs, biostratigraphy, TOC, and XRD measurements. The dataset was last updated in March 2026.

Use Cases

• Characterizing potential hydrocarbon source rocks based on mineralogical variations from HyLogging data.
• Refining stratigraphic correlation models across depocentres using integrated biostratigraphic and wireline log data.
• Identifying 'hot shale' units for petroleum exploration based on spectral response correlations with TOC and gamma.
• Testing correlative models across basin depocentres using middle Cambrian carbon isotope excursion data.

Strengths

• Data is internally consistent, reprocessed using a common set of mineral scalars for basin-wide analysis.
• Multidisciplinary integration includes HyLogging, wireline logs, biostratigraphy, TOC, and XRD measurements.
• Covers a significant geographic area of 325,000 km² within the Georgina Basin.

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 studied.
