Hydrocarbon Family Geochemistry in the Bonaparte Basin

Geochemical characteristics of hydrocarbon families and petroleum systems in the Bonaparte Basin, compiled by the Australian Ocean Data Network. The study analyzes oils and condensates from fields like Jabiru, Challis, and Skua, characterizing them into three distinct families based on bulk and compound-specific isotopes, GC, and GC-MS data. The dataset was last updated in April 2026.

Use Cases

• Classify oil samples into marine, terrestrially-influenced, or condensate families using bulk isotope and GC-MS data.
• Correlate hydrocarbon composition from fields like Maret and Montara to potential source rocks like the Lower-Middle Jurassic Plover Formation.
• Assess reservoir alteration effects such as leakage and gas flushing by analyzing condensate composition from the Tahbilk, Swan, and Eclipse fields.
• Map the geographic distribution of oil families, linking the terrestrially-influenced family to the southern Vulcan Sub-basin and northern Browse Basin.
• Evaluate the maturity and liquid potential of source rocks in the Skua Trough using geochemical data from associated oils.

Strengths

• Defines three distinct hydrocarbon families based on detailed geochemical analyses.
• Covers multiple producing and depleted fields including Jabiru, Challis, Skua, and Montara.
• Includes analyses of both oils and condensates, capturing a range of hydrocarbon types.

Limitations

• Specific sample count, row count, and data volume are unknown.
• Primary data formats are HTML and PDF, which may require extraction for computational analysis.
• Geographic focus is limited to the Vulcan Sub-basin and northern Browse Basin.
