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

31 wells and 25 depocentre sites were analyzed to model hydrocarbon generation and expulsion in the Browse Basin. The models incorporate new palaeo-bathymetric estimates and kerogen kinetic data for multiple potential source units. Results suggest multiple effective gas sources and localized oil charge, particularly in the Heywood Graben and Serringapatam Sub-basin.

Use Cases

• Modeling hydrocarbon expulsion timing and volumes based on subsidence and thermal history.
• Assessing source rock potential and charge risk for specific geological formations like the Plover and Lower Vulcan.
• Identifying exploration opportunities in outboard areas based on modelled fluid migration driven by carbonate clinoforms.

Strengths

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

Limitations

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