Geochemical Characteristics of Hydrocarbon Families in the Bonaparte Basin

Data from the Australian Ocean Data Network characterizes the geochemistry of oils and condensates from the Vulcan Sub-basin. The study, last updated in April 2026, groups hydrocarbons into three families based on bulk and compound-specific isotope analyses, GC, and GC-MS. It focuses on identifying oil-prone petroleum systems distinct from the established Jabiru and Challis-Cassini fields.

Use Cases

• Classifying hydrocarbon families based on geochemical composition described in the study
• Modeling petroleum system boundaries and source rock contributions based on oil family locations
• Assessing reservoir alteration effects like leakage and gas flushing using condensate composition data
• Correlating oil samples to potential source rock formations like the Plover Formation

Strengths

• Data is derived from specific geochemical analyses including bulk and compound-specific isotopes, GC, and GC-MS
• Characterizes three distinct hydrocarbon families with defined member fields
• Provides spatial context linking oil families to specific sub-basins and troughs

Limitations

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