Offshore Northern Perth Basin: Petroleum Prospectivity and Seismic Data

Geoscience Australia assessed the petroleum prospectivity of the large Release Area W11-18, covering parts of the Abrolhos, Houtman, and Vlaming sub-basins. The assessment synthesizes data from fourteen new field wildcat wells drilled since 2001 and interprets new regional 2D seismic data from a 2008-2009 survey. A refined tectono-stratigraphic model provides insights into basin evolution and prospectivity for oil and gas.

Use Cases

• Model petroleum prospectivity based on the refined tectono-stratigraphic framework for the offshore basin.
• Analyze basin evolution and play types based on interpretations of new regional 2D seismic data.
• Assess the extent of proven petroleum systems using data from fourteen new field wildcat wells.
• Evaluate exploration potential in water depths predominantly less than 200 meters within the release area.

Strengths

• Assessment includes synthesis of data from fourteen new field wildcat wells drilled since 2001.
• Interpretation is based on new regional 2D seismic data acquired during a 2008-2009 survey.
• Analysis covers a very large block (Release Area W11-18) adjacent to the producing Cliff Head oil field.

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 Australian offshore region.
