UV Fluorescence Spectra of 120 Offshore Western Australian Oils

120 oil samples from offshore Western Australia were analyzed for their ultraviolet fluorescence emission spectra. The Australian Geological Survey Organisation conducted this study to correlate airborne laser fluorosensor survey data with known petroleum systems. This dataset represents the first stage of a multi-client remote sensing study.

Use Cases

• Correlate airborne laser fluorosensor (ALF) survey anomalies with known oil samples using their 280-500 nm emission spectra.
• Characterize the type and quantity of aromatic hydrocarbons present in oil samples based on fluorescence intensity at 266 nm excitation.
• Classify offshore Western Australian oils into known petroleum systems using their spectral signatures.
• Validate remote sensing data by comparing field ALF measurements with laboratory UV fluorescence spectra of reference oils.

Strengths

• Contains fluorescence spectra for 120 distinct oil samples.
• Spectral data is explicitly compatible with the specific 266 nm excitation wavelength used by operational ALF systems.
• Oils represent all known offshore Western Australian petroleum systems as defined in contemporary studies.

Limitations

• Sample size is limited to 120 oils, which may not capture the full diversity of regional hydrocarbons.
• Data is from a concluded study stage (the first stage), indicating it is a static snapshot and not updated.
• Primary data files are packaged in a ZIP with HTML reports, which may require extraction and parsing.
