Unconventional Middle Cambrian Petroleum Systems in the Georgina Basin

Geoscience Australia's assessment of shale gas and oil potential in the Georgina Basin. The evaluation covers an area of approximately 325,000 square kilometers and relies on stratigraphy, tectonic history, petrography, and petroleum systems modeling. The data includes geochemical analysis of source rocks, with TOC and HI values up to 15.5% and 500 mg hydrocarbons/g TOC, respectively.

Use Cases

• Assessing shale gas and oil resource potential based on geochemical source rock data.
• Modeling petroleum systems using stratigraphy and tectonic history.
• Identifying hydrocarbon migration patterns based on descriptions of oil staining and biodegradation.
• Evaluating the maturity of source rocks using Rock Eval and isotopic data.

Strengths

• Covers a large geographic area of approximately 325,000 square kilometers.
• Includes specific geochemical measurements, such as TOC up to 15.5% and HI up to 500 mg hydrocarbons/g TOC.
• Based on methodology developed by the United States Geological Survey.

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 data_gov_au.
