Surat Basin Geology and Resource Estimates

Jurassic and Cretaceous sediments up to 2500 meters thick form the Surat Basin in Queensland, Australia. The Australian Ocean Data Network published this geological bulletin detailing stratigraphy, depositional history, and resource estimates, including 51 billion cubic meters of gas and 31 million cubic meters of oil as of 1974. The document was last updated in April 2026.

Use Cases

• Analyze the relationship between Jurassic fluviatile megacycles and Early Cretaceous marine incursions described in the stratigraphic text.
• Model basin evolution using described structural features like drape folds, faults, and epeirogenic tilting events.
• Benchmark historical hydrocarbon reserves against current data using the 1974 estimates of gas and oil volumes.
• Assess coal and oil shale potential from descriptions of the Walloon Coal Measures.

Strengths

• Detailed geological history covering multiple epochs from Jurassic to Miocene.
• Includes specific quantitative resource estimates: 51 billion m³ gas and 31 million m³ oil.
• Published and maintained by an authoritative national organization, the Australian Ocean Data Network.

Limitations

• Resource estimates are from 1974 and may not reflect current reserves.
• Data is presented in descriptive text (PDF/HTML) formats, not structured tabular data.
• Sample data and specific columnar data are unavailable for direct computational analysis.
