Browse Basin Hydrocarbon Prospectivity Study for Offshore Northwest Australia

The Browse Basin offshore Northwest Australia is a proven hydrocarbon province. Geoscience Australia conducted a multi-disciplinary study analyzing Cretaceous supersequences, sequence stratigraphy, and structural frameworks to assess regional petroleum systems and high-grade areas with liquids potential. The study integrated updated biostratigraphy, well log analysis, seismic interpretation, and geochemical data into a regional petroleum systems model.

Use Cases

• Model petroleum systems based on integrated geochemical studies of source rocks and fluids.
• Map play fairways based on interpreted Cretaceous supersequence stratigraphy and structural frameworks.
• Assess reservoir and seal pair relationships based on spatial analyses of the Cretaceous succession.
• Evaluate hydrocarbon generation potential based on burial history modelling of Jurassic and Lower Cretaceous source rocks.
• Correlate hydrocarbon fluids with source rocks based on molecular and stable carbon/hydrogen isotopic signatures.

Strengths

• Analysis covers seven Cretaceous supersequences from the late Tithonian to Maastrichtian.
• Study integrates multiple data types including biostratigraphy, well logs, seismic data, and geochemistry.
• Identifies three main Cretaceous stratigraphic play types: basin-margin, clinoform topset, and submarine fan plays.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified; last updated date is 2026-06-23.
