Offshore Northern Perth Basin Petroleum Prospectivity Assessment

Geoscience Australia assessed the petroleum prospectivity of Release Area W11-18 in the offshore northern Perth Basin. The assessment synthesizes data from fourteen new wildcat wells drilled since 2001 and interprets regional 2D seismic data from a 2008-2009 survey. It identifies proven petroleum systems and multiple discoveries within the area.

Use Cases

• Evaluate basin evolution and prospectivity using the refined tectono-stratigraphic model.
• Identify potential plays and reservoir targets by analyzing interpreted Permo-Triassic strata from new seismic data.
• Assess source rock potential and petroleum system effectiveness using data from oil stain and fluid inclusion sampling.
• Map exploration opportunities across varying water depths, predominantly under 200 meters, within the release area.

Strengths

• Assessment includes data from fourteen new field wildcat wells drilled since 2001.
• Interpretation incorporates new regional 2D seismic data from a dedicated 2008-2009 survey.
• Report covers three known petroleum discoveries (Dunsborough-1, Frankland-1, Perseverance-1) within the area.

Limitations

• Specific row counts, column names, and raw data samples are unavailable.
• Primary data formats are HTML and PDF reports, not structured data tables.
• Spatial analysis is confined to a single release area (W11-18).
