Offshore Northern Perth Basin Petroleum Geochemistry Review

Geochemical data and analysis reassess petroleum systems in Australia's offshore northern Perth Basin. The work includes a review of source rock and oil data from wells like Cliff Head-1, Frankland-1, and Dunsborough-1. Geoscience Australia conducted this study to support the release of exploration blocks W13-19 and W13-20.

Use Cases

• Correlating oil samples to the Hovea Member source rock using geochemical typing data.
• Mapping petroleum system extent across the Houtman and Abrolhos Sub-basins using well control data from 6 locations.
• Analyzing source rock development and thickness (10-40 m) in the offshore basin for prospectivity assessment.
• Evaluating exploration history using data from 13 field wildcat wells drilled since 2002 and subsequent discoveries.

Strengths

• Analysis includes data from multiple discovery wells (Cliff Head-1, Frankland-1, Perseverance-1, Dunsborough-1).
• Study covers a major integrated review of source rock and oil geochemistry by Geoscience Australia.
• Well control is provided from 6 specific locations across the Wittecarra Terrace and Houtman Sub-basin.

Limitations

• Specific sample size, row count, and column details for the underlying geochemical data are unknown.
• Geographic scope is limited to the offshore northern Perth Basin, not the entire basin.
• Primary data format is an HTML report, which may require extraction for quantitative analysis.
