Offshore Northern Perth Basin Petroleum Prospectivity Assessment

Release Area W11-18 is a large offshore block covering parts of the Abrolhos, Houtman and Vlaming sub-basins. Geoscience Australia assessed its petroleum prospectivity using data from fourteen new field wildcat wells drilled since 2001 and new regional 2D seismic data from a 2008-2009 survey. The assessment includes a refined tectono-stratigraphic model and identifies three petroleum discoveries within the area.

Use Cases

• Evaluate petroleum prospectivity based on the synthesis of well and seismic data
• Model basin evolution based on the refined tectono-stratigraphic framework
• Assess exploration plays based on identified Permian and Jurassic petroleum systems
• Analyze hydrocarbon potential based on water depth information, predominantly less than 200 meters

Strengths

• Assessment incorporates data from fourteen new field wildcat wells drilled since 2001
• Includes interpretation of new regional 2D seismic data from a 2008-2009 survey
• Identifies three 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 bias inherent to data_gov_au
