Petroleum Systems Analysis for the Browse Basin, Offshore Australia

Geoscience Australia conducted a multi-disciplinary study integrating updated biostratigraphy, well correlations, seismic data, and paleogeographic interpretations for ten Hettangian to Maastrichtian supersequences. This regional petroleum systems model identifies four distinct petroleum systems and source rock distribution within the Browse Basin. The analysis highlights specific hydrocarbon accumulations, such as those in the Ichthys/Prelude and Burnside areas, sourced from Jurassic–Cretaceous formations.

Use Cases

• Modeling hydrocarbon generation and migration based on interpreted source pods and basin architecture.
• Identifying liquid-prone plays using geochemical analyses and depositional environmental models.
• Correlating well data and seismic interpretations across ten supersequences for regional understanding.
• Assessing the prospectivity of specific formations like the Plover, Vulcan, and Echuca Shoals.

Strengths

• Analysis is based on a multi-disciplinary study integrating biostratigraphy, seismic, well correlations, and geochemistry.
• Model identifies four distinct petroleum systems and specific hydrocarbon accumulations like Ichthys/Prelude.
• Study covers ten supersequences from the Hettangian to the Maastrichtian, providing a broad stratigraphic scope.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in PDF format, which may hinder direct computational analysis.
