Browse Basin Hydrocarbon Prospectivity Study with Geochemical and Stratigraphic Analysis

Geoscience Australia conducted a multi-disciplinary study of the Browse Basin to reassess its petroleum potential. The work includes updated biostratigraphy, well log analysis, seismic interpretation, and geochemical studies for seven Cretaceous supersequences. These were integrated into a regional petroleum systems model to understand source rock distribution and play prospectivity.

Use Cases

• Modeling petroleum systems based on integrated geochemical and stratigraphic data.
• Identifying play fairways based on mapped gross depositional facies and palaeogeographic interpretations.
• Correlating hydrocarbon fluids to source rocks using molecular and stable isotopic signatures.
• Assessing seal quality and thickness for basin-margin, clinoform topset, and submarine fan plays.

Strengths

• Analysis covers seven defined Cretaceous supersequences (K10–K60) from the late Tithonian to Maastrichtian.
• Integrates multiple data types including biostratigraphy, well logs, seismic stratal geometry, and geochemical fingerprints.
• Identifies four distinct 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.
