Offshore Northern Perth Basin Petroleum Systems Reassessment by Geoscience Australia

Geoscience Australia conducted a review of source rock and oil geochemical data for the offshore northern Perth Basin. The work supports the release of two major offshore exploration blocks, W13-19 and W13-20, and references data from 5 wells on the Wittecarra Terrace and the Houtman-1 well. The dataset was last updated on 2026-04-20.

Use Cases

• Reassessing basin prospectivity based on integrated geochemical data review.
• Correlating oil types to source rock units like the Hovea Member.
• Evaluating exploration potential for new blocks like W13-19 and W13-20.
• Analyzing the extension of onshore petroleum systems into offshore sub-basins.

Strengths

• Data is associated with a major integrated study by Geoscience Australia, a national authority.
• Supports the release of two specific exploration blocks, W13-19 and W13-20.
• Well control is provided by 5 wells from the Wittecarra Terrace and the Houtman-1 well.

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 specific offshore northern Perth Basin study area.
