Offshore Northern Perth Basin Petroleum Systems Review Supporting Exploration Blocks

Geoscience Australia conducted a review of source rock and oil geochemical data in the offshore northern Perth Basin. The work supports the release of exploration areas W13-19 and W13-20 and reassesses the basin's prospectivity based on data from wells like Cliff Head-1 and Houtman-1. The dataset was last updated on 2026-05-14.

Use Cases

• Reassessing regional petroleum systems based on source rock and oil geochemical data.
• Evaluating the extension of onshore petroleum systems offshore based on oil typing evidence.
• Supporting exploration decisions for blocks W13-19 and W13-20 using well control data.
• Analyzing the distribution of the Hovea Member source rock across the Permian-Triassic boundary.

Strengths

• Based on a major integrated study by Geoscience Australia, a national geological survey.
• Supports specific exploration blocks (W13-19, W13-20) with defined geographic scope.
• Incorporates data from key discovery wells like Cliff Head-1, Frankland-1, and Perseverance-1.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
