New Exploration Opportunities in the Offshore Northern Perth Basin: Release Area W11-18

Geoscience Australia's assessment of petroleum prospectivity for the offshore northern Perth Basin, specifically Release Area W11-18. 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. It describes a refined tectono-stratigraphic model, three known petroleum discoveries, and evidence for active Permo-Triassic and Jurassic petroleum systems.

Use Cases

• Evaluate petroleum prospectivity based on the refined tectono-stratigraphic model for the offshore basin.
• Identify potential drilling targets based on the interpretation of new regional 2D seismic data.
• Assess the extension of proven onshore petroleum systems into offshore areas based on source rock and fluid inclusion sampling.
• Analyze play types and water depths, which are predominantly less than 200 meters, for exploration planning.

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 dedicated 2008-2009 survey.
• Describes three specific petroleum discoveries (Dunsborough-1, Frankland-1, Perseverance-1) within the release area.

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 and temporal bias inherent to the specific survey and assessment program.
