A 2026 review of source rock and oil geochemical data from Geoscience Australia, supporting the release of offshore exploration areas W13-19 and W13-20. The dataset covers the offshore northern Perth Basin, including the Houtman, Abrolhos, Zeewyck, and Gascoyne Sub-basins. It was compiled by the Australian Ocean Data Network as part of an integrated study to reassess the basin's prospectivity.
Use Cases
- Correlating oil types to source rock units based on geochemical data mentioned in the description.
- Mapping petroleum system extent offshore using data from wells like Cliff Head-1, Frankland-1, and Dunsborough-1.
- Assessing exploration prospectivity for new license areas like W13-19 and W13-20.
- Evaluating the development of the Hovea Member source rock across the Permian-Triassic boundary offshore.
Strengths
- Includes data from 13 new field wildcat wells drilled since 2002.
- Well control is provided by 5 wells from the Wittecarra Terrace and Houtman-1.
- Supports the release of two major exploration blocks (W13-19, W13-20).
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 data_gov_au, focusing on a specific basin region.
