New Exploration Opportunities in the Offshore Northern Perth Basin

Geoscience Australia assessed petroleum prospectivity for Release Area W11-18, a very large offshore block. The assessment synthesizes data from fourteen new field wildcat wells drilled since 2001 and interprets new regional 2D seismic data from survey 310 (2008-2009). A refined tectono-stratigraphic model provides insights into basin evolution and prospectivity.

Use Cases

• Evaluate petroleum prospectivity based on the synthesis of fourteen new wildcat wells.
• Model basin evolution using the refined tectono-stratigraphic framework.
• Identify potential plays in water depths predominantly less than 200 meters.
• Assess the extent of proven Permian and Jurassic petroleum systems in the offshore basin.

Strengths

• Assessment includes first published synthesis of data from fourteen new field wildcat wells.
• Interpretation incorporates new regional 2D seismic data from a dedicated 2008-2009 survey.
• Release Area contains three petroleum discoveries and is 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.
