New Exploration Opportunities in the Offshore Northern Perth Basin

Geoscience Australia assessed petroleum prospectivity for Release Area W11-18 in the offshore northern Perth Basin. The assessment synthesizes data from fourteen new wells drilled since 2001 and interprets new regional 2D seismic data acquired in 2008-2009. It includes a refined tectono-stratigraphic model and evidence for active Permian-Triassic and Jurassic petroleum systems.

Use Cases

• Evaluate petroleum prospectivity based on the synthesis of fourteen new field wildcat wells.
• Interpret basin evolution and stratigraphy using a refined tectono-stratigraphic model.
• Identify hydrocarbon plays based on seismic data showing Permo-Triassic strata in half-graben.
• Assess the extent of proven petroleum systems using source rock, oil stain, and fluid inclusion sampling.

Strengths

• Assessment includes data from fourteen new wells drilled since the 2001 Cliff Head discovery.
• Incorporates interpretation of new regional 2D seismic data from a 2008-2009 survey.
• Covers a large offshore block with three known petroleum discoveries and an adjacent producing oil field.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
