ALF Compatible UV Fluorescence Spectra of 120 Offshore Western Australia Oils

120 oil samples from offshore Western Australia were analyzed for ultraviolet fluorescence emission spectra. The data were collected by Geoscience Australia's Petroleum and Marine Division to correlate airborne laser fluorosensor survey anomalies with known petroleum systems. This report concludes the first stage of a multi-client study on using fluorescence signatures for hydrocarbon seep detection and typing.

Use Cases

• Correlating airborne laser fluorosensor survey anomalies with known oil types based on fluorescence signatures.
• Characterizing the aromatic hydrocarbon composition of oils from different Western Australian petroleum systems.
• Developing models to type hydrocarbon seeps directly to their source using laboratory-calibrated spectral data.

Strengths

• Contains spectra for 120 oil samples, representing all known offshore Western Australian petroleum systems at the time of the study.
• Laboratory data is explicitly compatible with the specific 266 nm excitation wavelength used by a commercial airborne laser fluorosensor system.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; the underlying study and data collection period are not specified in the provided metadata.
