Geochemical Characteristics of Hydrocarbon Families in the Bonaparte Basin

Geochemical analyses of oils and condensates from the Vulcan Sub-basin have characterized them into three distinct families. The study, sourced from Geoscience Australia Data, focuses on differentiating oil-prone petroleum systems beyond the established Jabiru and Challis-Cassini fields. It identifies a marine oil family, a terrestrially-influenced oil family, and a family of condensates, with probable source rocks in the Lower-Middle Jurassic Plover Formation.

Use Cases

• Classifying hydrocarbon families based on bulk and compound-specific isotope data mentioned in the description
• Modeling petroleum system boundaries based on the spatial distribution of the terrestrially-influenced oil family
• Assessing reservoir alteration effects (e.g., leakage, gas flushing) using the composition of condensates from Tahbilk, Swan, and Eclipse
• Correlating oils to source rocks, such as the Upper Jurassic Lower Vulcan Formation and the Lower-Middle Jurassic Plover Formation

Strengths

• Analysis characterizes oils and condensates into three distinct geochemical families
• Study focuses on differentiating oil compositions beyond the well-known Jabiru and Challis-Cassini fields
• Identifies probable source rock formations, including the Lower-Middle Jurassic Plover Formation

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the Vulcan and Browse Basins study area
