Natural Gas Isotope Compositions from the Perth Basin, Australia

34 natural gas samples from the onshore and offshore Perth Basin, Australia, analyzed for molecular composition and carbon and hydrogen isotopic signatures. The dataset extends a previous study and provides evidence for Jurassic to Permian gas systems. It is provided by Geoscience Australia Data and was last updated in 2026.

Use Cases

• Identify gas source rock maturity and type based on carbon and hydrogen isotope systematics.
• Correlate natural gases to specific geological formations like the Kockatea Shale or Permian sources.
• Model the extent and mixing of different petroleum systems in the Perth Basin.
• Validate geochemical models of hydrocarbon generation using molecular composition data.

Strengths

• Includes 34 distinct natural gas samples.
• Extends previous work by adding hydrogen isotope data and offshore samples.
• Links geochemical data to specific geological intervals like the Early Triassic Kockatea Shale.

Limitations

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