Browse Basin Hydrocarbon Prospectivity Study with Geochemical and Stratigraphic Data

Geoscience Australia conducted a multi-disciplinary study of the Browse Basin, analyzing seven Cretaceous supersequences from the late Tithonian to Maastrichtian. The study integrated updated biostratigraphy, well log analysis, seismic geometry, and geochemical studies into a regional petroleum systems model. It identified three main Cretaceous stratigraphic play types and four Mesozoic petroleum systems based on geochemical fingerprinting.

Use Cases

• Modeling petroleum systems based on integrated stratigraphic, structural, and geochemical data mentioned in the description
• High-grading areas for liquids potential within Cretaceous supersequences based on the regional prospectivity study
• Correlating hydrocarbon fluids with source rocks using molecular and stable isotopic signatures described in the study
• Analyzing the spatial relationship of reservoir and seal pairs within the Cretaceous structural framework

Strengths

• Analysis covers seven defined Cretaceous supersequences (K10–K60) providing a structured temporal framework
• Study integrates multiple data types including biostratigraphy, seismic stratal geometry, and geochemical fingerprinting
• Identifies three specific Cretaceous 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 files are in PDF and HTML formats, which may require extraction for computational analysis
