Natural Gas Isotope Compositions from the Onshore and Offshore Perth Basin

Australian Ocean Data Network hosts a study analyzing the molecular and isotopic composition of 34 natural gas samples from the Perth Basin. The research extends a previous 2001 study to include offshore samples and hydrogen isotope data. It was last updated on June 27, 2026.

Use Cases

• Identify gas source rock age and type based on carbon and hydrogen isotope systematics mentioned in the description.
• Correlate gas samples to specific geological formations like the Kockatea Shale based on geochemical data.
• Distinguish between Jurassic and Permian gas systems in the Perth Basin based on isotopic signatures.
• Assess the contribution of non-Kockatea source rocks to gas accumulations using molecular composition data.

Strengths

• Includes data from 34 distinct natural gas samples.
• Extends previous research by incorporating offshore samples and hydrogen isotope data.
• Focuses on a specific, well-defined geological region: the onshore and offshore Perth Basin.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data files are in PPTX and PDF formats, which are not typical for structured data analysis.
