Natural Gas Isotope Compositions from the Perth Basin, Australia

A study of 34 natural gas samples from the onshore and offshore Perth Basin, Australia, analyzing molecular and isotopic compositions. The data extends a previous 2001 study to include offshore samples and hydrogen isotopes, revealing Jurassic to Permian gas systems. The dataset is provided by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Identify gas source rocks based on carbon and hydrogen isotope systematics mentioned in the description
• Correlate natural gases to specific geological intervals like the Early Triassic Kockatea Shale referenced in the study
• Model the existence of multiple gas systems (Jurassic to Permian) in the Perth Basin as indicated by the research

Strengths

• Analysis of 34 natural gas samples provides a substantive sample size for basin-scale study
• Includes both carbon and hydrogen isotope data, extending a prior 2001 study
• Covers both onshore and offshore regions of the Perth Basin

Limitations

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