Petroleum Source Analysis for the Bowen and Surat Basins

A geochemical dataset analyzes natural gases and 130 core samples from potential source rocks in the Bowen and Surat basins. Biomarker and stable carbon-isotope analysis indicates a dominant Permian terrestrial plant source with minor marine and Triassic influences. The dataset was published by the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Modeling petroleum generation history based on biomarker analysis results
• Correlating petroleum sources to specific geological periods using stable carbon-isotope data
• Assessing the liquid hydrocarbon potential of different coal facies described in the dataset
• Studying the timing of liquid expulsion and gas generation phases using vitrinite reflectance values

Strengths

• Includes analysis of 130 core samples, providing a substantial material basis for conclusions
• Biomarker and stable carbon-isotope analyses provide two distinct lines of geochemical evidence
• Specifies quantitative maturation thresholds, such as liquid expulsion beginning at vitrinite reflectance of 0.65-0.7%

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for large-scale modeling
• Data freshness should be verified despite the 2026 update date, as the underlying samples are likely historical
