Geology and Resource Assessment of the Surat Basin, Queensland

Jurassic and Cretaceous sediments up to 2500 meters thick form the Surat Basin in eastern Australia. The geological description details fluvial deposition, marine incursions, volcanic activity, and subsequent erosion and weathering. It includes a 1974 resource estimate of 51 billion cubic meters of gas and 31 million cubic meters of oil, alongside coal and oil shale reserves in the Walloon Coal Measures.

Use Cases

• Stratigraphic analysis based on described Jurassic-Cretaceous fining-upward megacycles
• Hydrocarbon resource estimation based on the 1974 petroleum reserve figures
• Basin evolution modeling based on described tectonic history and marine incursions
• Coal and unconventional resource assessment based on mentions of the Walloon Coal Measures

Strengths

• Provides specific quantitative resource estimates from 1974
• Includes detailed geological history covering multiple epochs from Jurassic to Miocene
• Cross-platform presence on a government data portal suggests official provenance

Limitations

• No column names or structured data are provided; the dataset appears to be a textual publication
• Key metadata such as row count, license, and author are consistently listed as unknown or null
• The resource estimates are from 1974 and may not reflect current assessments
