Georgina Basin Mineralogy And Stratigraphy From HyLogging Data

A synopsis presents initial results from a regional study on the hydrocarbon prospectivity of the southern Georgina Basin in Australia. The work integrates reprocessed HyLogging mineralogical data from 25 wells with wireline logs, biostratigraphy, total organic carbon content, and X-ray diffraction measurements. The study was conducted by Geoscience Australia's Onshore Energy Systems Group, with referenced work from 2014.

Use Cases

• Identify potential source rock units by analyzing correlations between HyLogging spectral response, total gamma, and total organic carbon (TOC) in the Arthur Creek Formation.
• Refine stratigraphic correlation models across the Dulcie and Toko synclines using integrated HyLogging data, wireline logs, and biostratigraphic data.
• Characterize mineralogical variations within formations like the Thorntonia Limestone using reprocessed HyLogging data with common mineral scalars.
• Investigate age discrepancies in the 'hot shale' unit using recent biostratigraphic work and middle Cambrian carbon isotope excursion data.

Strengths

• Integrated dataset combining HyLogging mineralogy from 25 wells with wireline logs, biostratigraphy, TOC, and XRD measurements.
• Reprocessed HyLogging data using a common set of mineral scalars to create an internally-consistent, basin-wide dataset.
• Focus on a defined geographic area covering 325,000 km2 of the Georgina Basin in western Queensland and the Northern Territory.

Limitations

• Specific row counts, sample sizes, and full data availability for integrated datasets (TOC, XRD) are not provided.
• The description is a synopsis of initial results, suggesting the underlying raw data files may be separate and their formats/access are unclear.
• Temporal coverage and update frequency for the core datasets are not specified.
