Offshore Northern Perth Basin Petroleum System Geochemical Review

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

Use Cases

• Analyze source rock geochemical data to reassess petroleum prospectivity in the Houtman and Abrolhos Sub-basins.
• Correlate oil typing data from wells like Cliff Head-1 to evaluate the offshore extension of the Hovea Member source unit.
• Map the distribution of petroleum systems using well control data from the Wittecarra Terrace and Houtman Sub-basin.

Strengths

• Data underpins a major integrated study by the national geological survey, Geoscience Australia.
• Review references specific exploration blocks (W13-19, W13 20) and 5 key wells for control.
• Focuses on a revitalized exploration area with 13 new field wildcat wells drilled since 2002.

Limitations

• Dataset scope and structure (rows, columns, file formats) are not specified in the provided input.
• Primary data appears embedded within a geological review publication rather than as a standalone tabular resource.
• Temporal coverage of the underlying geochemical samples is not explicitly defined.
