Petroleum Origin in Bowen and Surat Basins: Source, Maturation, and Migration

The Australian Ocean Data Network hosts data on the origin of petroleum in the Bowen and Surat basins. The dataset is based on analysis of natural gases and 130 core samples from potential source rocks, resolving generation and migration history. Biomarker and stable carbon-isotope analysis identified Permian and minor Triassic terrestrial and marine sources.

Use Cases

• Modeling hydrocarbon generation windows based on vitrinite reflectance (Ro) thresholds mentioned in the description
• Correlating petroleum to source rock facies based on analysis of lower vs. upper delta plain coals
• Differentiating source contributions using biomarker and stable carbon-isotope data described
• Assessing liquid and gas potential of Permian coal facies as indicated in the description

Strengths

• Analysis is based on 130 core samples from potential source rocks
• Biomarker and stable carbon-isotope analyses provide two distinct lines of geochemical evidence
• Specific maturation thresholds for liquid expulsion (Ro 0.65-0.7%) and gas generation (Ro >1.05%) are provided

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 PDF and HTML formats, which may require extraction for computational analysis
