Geology of the Surat Basin in Queensland with Petroleum and Coal Reserves

2500 meters of Jurassic and Cretaceous sediments form the Surat Basin in eastern Australia. Petroleum reserves were estimated in 1974 as 51 billion cubic meters of gas and 31 million cubic meters of oil, and the Walloon Coal Measures hold considerable bituminous coal and oil shale reserves. The dataset is provided by the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Modeling sedimentary basin evolution based on described Jurassic and Cretaceous depositional sequences.
• Estimating hydrocarbon resource potential based on the 1974 petroleum reserve figures.
• Assessing coal and oil shale reserves based on the description of the Walloon Coal Measures.
• Studying geological structures based on mentions of drape folds, compaction folds, and faults.

Strengths

• Includes specific resource estimates: 51 billion m³ of gas and 31 million m³ of oil.
• Describes a substantial geological sequence: 2500 meters of Jurassic and Cretaceous sediments.
• Provides temporal context for geological events, including Jurassic, Cretaceous, and Tertiary periods.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in HTML and PDF formats, which may require extraction for computational analysis.
