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

130 core samples and natural gas analyses enable resolution of petroleum generation and migration history in the Bowen and Surat basins. Biomarker and stable carbon-isotope analysis confirmed a dominant Permian terrestrial source with minor Triassic and marine influences. The data, from Geoscience Australia, details liquid expulsion and gas generation phases based on vitrinite reflectance measurements.

Use Cases

• Modeling hydrocarbon generation windows based on vitrinite reflectance (Ro) values from 0.65% to 1.05% mentioned in the description
• Correlating discovered petroleum to source rock facies based on biomarker and stable carbon-isotope analysis described
• Assessing the liquid hydrocarbon potential of different coal facies (e.g., lower vs. upper delta plain) as indicated in the description
• Differentiating between Permian and localized Triassic petroleum sources using the isotopic signatures described

Strengths

• Analysis is based on 130 core samples from potential source rocks, providing a material basis for conclusions
• Includes biomarker and stable carbon-isotope data, enabling source rock and maturity assessment
• Defines specific vitrinite reflectance windows for liquid expulsion (0.65-0.7% Ro) and main gas generation (>1.05% Ro)

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 statistical modeling
• Primary data files are in PDF and HTML formats, which may require extraction for computational analysis
