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 carbon, hydrogen, and helium isotope systematics. The data extends a previous 2001 study to include offshore samples and hydrogen isotopes, revealing Jurassic to Permian gas systems. It was published by Geoscience Australia Data.

Use Cases

• Identify gas source rocks based on molecular and isotopic compositions mentioned in the description.
• Correlate natural gases to specific geological intervals like the Early Triassic Kockatea Shale.
• Model hydrocarbon generation and migration in the Perth Basin using isotopic signatures.
• Compare onshore versus offshore gas systems in the basin as indicated by the study scope.

Strengths

• Includes 34 distinct natural gas samples for analysis.
• Extends previous work by adding offshore samples and hydrogen isotope data.
• Focuses on a defined geographical region, 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.
• Primary data files are in presentation (PPTX) and document (PDF) formats, which may require extraction of underlying data.
