ALF Compatible UV Fluorescence Spectra of 120 Offshore Western Australia Oils

AGSO's Petroleum and Marine Division produced this report containing ultraviolet fluorescence (UVF) emission spectra for 120 open file western Australian oils. The laboratory UVF data were collected by scanning the 280-500 nm emission response using an excitation wavelength of 266 nm to evaluate aromatic hydrocarbons. This report concludes the first stage of a multi-client 'remote sensing' study and is designed as a stand-alone product.

Use Cases

• Correlating sea surface hydrocarbon anomalies detected by ALF surveys with known oil samples based on fluorescence signatures.
• Typing hydrocarbon seeps to their geological sources using the UVF spectral data.
• Comparing laboratory UVF spectra of known oils with field ALF survey data for offshore Western Australia.
• Characterizing the aromatic hydrocarbon content present in offshore Western Australian oil samples.

Strengths

• Contains spectra for 120 oil samples, representing all known offshore Western Australian petroleum systems as defined by referenced studies.
• Data is explicitly compatible with the Airborne Laser Fluorosensor (ALF) system operated by World Geoscience Corp. Ltd., using the same 266 nm excitation wavelength.
• Report integrates supplementary geological and geochemical information from 'The Oils of Western Australia' study.

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; last metadata update was 2026-06-04.
