Subsidence and Thermal History Models for Hydrocarbon Expulsion in the Browse Basin

31 wells and 25 depocentre sites were analyzed for subsidence and thermal history to examine Jurassic and Early Cretaceous petroleum systems in the Browse Basin. The models incorporate new palaeo-bathymetric estimates and kerogen kinetic data for multiple potential source units. The dataset was published by the Australian Ocean Data Network and was last updated on 2026-06-27.

Use Cases

• Modeling hydrocarbon expulsion timing and volumes based on subsidence and thermal history data.
• Assessing source rock effectiveness for oil and gas charge based on kerogen kinetic parameters.
• Identifying exploration opportunities in outboard areas based on modeled fluid migration from carbonate clinoforms.
• Evaluating the impact of Late Tertiary geological events on petroleum system evolution.

Strengths

• Analysis is based on data from 31 wells and 25 depocentre sites.
• Models incorporate new palaeo-bathymetric estimates and detailed benthic foraminiferal data.
• Includes new kerogen kinetic data for multiple potential source units.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
