Browse Basin Petroleum Prospectivity Study: Cretaceous Supersequence Analysis

The Browse Basin offshore Northwest Australia is a proven hydrocarbon province. Geoscience Australia conducted a multi-disciplinary study analyzing Cretaceous supersequences to assess regional hydrocarbon prospectivity and high-grade areas with increased liquids potential. The study integrated sequence stratigraphy, structural framework, biostratigraphy, well logs, seismic data, palaeogeography, and geochemical analyses to model petroleum systems.

Use Cases

• Modeling petroleum systems based on integrated geochemical and stratigraphic data mentioned in the description
• Identifying play fairways based on the analysis of Cretaceous supersequence reservoir and seal pairs
• Correlating hydrocarbon fluids to source rocks based on molecular and stable isotopic geochemical fingerprints
• Assessing burial history and hydrocarbon generation potential based on regional deposition mapping

Strengths

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

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
