Natural Gas Isotope Compositions from the Perth Basin, Australia

34 natural gas samples from the onshore and offshore Perth Basin were analyzed for molecular composition and carbon and hydrogen isotopes. The study extends previous work by Boreham et al. (2001) and includes offshore samples and hydrogen isotope data. It demonstrates the existence of Jurassic to Permian gas systems in the basin.

Use Cases

• Identify gas source rock age based on carbon and hydrogen isotope systematics.
• Correlate offshore and onshore gas systems using molecular composition data.
• Validate the presence of non-Kockatea Shale sourced gases using isotopic evidence.

Strengths

• 34 gas samples provide a substantial basis for analysis.
• Includes both onshore and offshore samples, offering geographic breadth.
• Extends a previous study (Boreham et al., 2001) with new hydrogen isotope data.

Limitations

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