Browse Basin Hydrocarbon Prospectivity Assessment for Cretaceous Plays

Geoscience Australia conducted a multi-disciplinary study reassessing petroleum prospectivity in the Browse Basin offshore Northwest Australia. The analysis integrated updated biostratigraphy, well log analysis, seismic interpretation, and geochemical studies for seven Cretaceous supersequences from the late Tithonian to Maastrichtian. This work identified three main Cretaceous stratigraphic play types and four Mesozoic petroleum systems through burial history and petroleum systems modeling.

Use Cases

• Identify hydrocarbon prospectivity areas based on integrated sequence stratigraphy and structural framework analysis.
• Correlate fluids to source rocks using molecular and stable carbon/hydrogen isotopic signatures described in the study.
• Model petroleum systems and burial history for Jurassic and Lower Cretaceous supersequences as detailed in the description.
• Map the distribution of gross depositional facies for basin-margin, clinoform topset, and submarine fan plays.

Strengths

• Analysis covers seven Cretaceous supersequences (K10–K60) providing a detailed stratigraphic framework.
• Study integrates multiple data types including biostratigraphy, well logs, seismic data, and geochemistry.
• Petroleum systems modeling identifies four distinct Mesozoic source rock systems.

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 quantitative analysis.
