Offshore Northern Perth Basin Petroleum Systems and Geochemical Data

The offshore northern Perth Basin in Western Australia is the focus of this geochemical dataset. Geoscience Australia compiled source rock and oil geochemical data to reassess the basin's prospectivity, supporting the release of exploration blocks W13-19 and W13-20. The work was informed by data from 5 wells on the Wittecarra Terrace and the Houtman-1 well.

Use Cases

• Correlating discovered hydrocarbons to source rocks based on geochemical typing data mentioned in the description
• Mapping the offshore extent of the Hovea Member petroleum system based on the review of source rock data
• Evaluating exploration risk in the Houtman and Abrolhos Sub-basins using the integrated geochemical study
• Supporting bid assessments for offshore exploration blocks W13-19 and W13-20 with the reviewed prospectivity data

Strengths

• Data is tied to specific exploration blocks (W13-19, W13-20) and sub-basins (Houtman, Abrolhos, Zeewyck, Gascoyne).
• Analysis includes geochemical typing that linked Cliff Head oil to the onshore Hovea Member source rock.
• The study integrates data from 5 wells on 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.
• Freshness should be verified; last metadata update was 2026-04-30.
