Browse Basin Hydrocarbon Prospectivity Study, Offshore Northwest Australia

The Browse Basin offshore Northwest Australia is a proven hydrocarbon province. Geoscience Australia conducted a multi-disciplinary study integrating sequence stratigraphy, structural framework, biostratigraphy, well log analysis, seismic interpretation, and geochemistry to reassess petroleum systems and play types from the late Tithonian to Maastrichtian. The study produced regional petroleum systems models, cross-sections, and palaeogeographic maps.

Use Cases

• Model regional petroleum systems based on integrated geochemical and stratigraphic data.
• Identify Cretaceous stratigraphic play types (basin-margin, clinoform topset, submarine fan) based on facies distribution maps.
• Correlate hydrocarbon fluids with source rocks using molecular and stable isotopic signatures described in the study.
• Assess seal quality and thickness for basin margin plays based on facies pinch-out and truncation analysis.

Strengths

• Study covers seven Cretaceous supersequences (K10–K60) from late Tithonian to Maastrichtian.
• Analysis integrates multiple disciplines: sequence stratigraphy, structural framework, biostratigraphy, well log analysis, seismic interpretation, and geochemistry.
• Identifies four Mesozoic petroleum systems and three main Cretaceous stratigraphic play types.

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 the specific basin study.
