Description
Geoscience Australia's systematic evaluation of shale gas and oil potential in the Georgina Basin, covering an area of approximately 325,000 square kilometers. The assessment relies on updated stratigraphy, tectonic history, petrography, geochemistry, and petroleum systems modeling, with a focus on Middle Cambrian source rocks like the Thorntonia Limestone and Arthur Creek Formation. Data includes geochemical characterizations such as isotopic depletion, hydrocarbon abundances, and source richness estimates derived from Rock Eval and other analyses.
Use Cases
Modeling unconventional petroleum systems based on geochemical source rock data
Estimating hydrocarbon resource potential based on basin-wide oil staining and source rock maturity
Analyzing stratigraphic and tectonic controls on petroleum systems mentioned in the description
Correlating geochemical signatures like isotopic depletion and terpane content for basin analysis
Strengths
Assessment covers a basin area of approximately 325,000 square kilometers
Source rock data includes specific geochemical metrics like TOC up to 15.5% and HI up to 500 mg hydrocarbons/g TOC
Analysis incorporates multiple datasets: stratigraphy, tectonic history, petrography, geochemistry, and petroleum systems modeling
Limitations
Column-level documentation is absent; field semantics must be inferred after download
Row count is unknown, which may limit suitability assessment
