Browse Basin Hydrocarbon Prospectivity Study with Geochemical and Stratigraphic Analysis

Geoscience Australia conducted a multi-disciplinary study of the Browse Basin to assess regional hydrocarbon prospectivity. The work includes updated biostratigraphy, well log analysis, seismic interpretation, and geochemical studies for seven Cretaceous supersequences, integrated into a regional petroleum systems model. The study maps the deposition of Permo-Carboniferous to Cenozoic successions to constrain burial history and identifies three main Cretaceous stratigraphic play types.

Use Cases

• Modeling petroleum systems based on integrated geochemical and stratigraphic data mentioned in the description
• Identifying play fairways based on mapped gross depositional facies and palaeogeographic interpretations
• Correlating hydrocarbon fluids to source rocks using molecular and stable isotopic signatures described in the study
• Assessing seal quality and reservoir distribution for Cretaceous supersequences analyzed in the basin

Strengths

• Study integrates multiple data types including biostratigraphy, well logs, seismic data, and geochemistry
• Analysis covers seven defined Cretaceous supersequences (K10–K60) from the late Tithonian to Maastrichtian
• Identifies and characterizes three specific Cretaceous stratigraphic play types: basin-margin, clinoform topset, and submarine fan

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
