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 model hydrocarbon generation and expulsion. The models incorporate new palaeo-bathymetric estimates and kerogen kinetic data for Jurassic and Early Cretaceous petroleum systems. Results suggest multiple effective gas sources, with significant oil expulsion modelled for the Heywood Graben and deepwater Seringapatam Sub-basin during the Tertiary.

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 data.
• Evaluating exploration potential in outboard areas based on modelled Late Tertiary carbonate clinoform impacts.
• Calibrating regional petroleum system models with well-specific palaeo-bathymetric estimates.

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.
• Data is presented in PDF/HTML formats, which may require extraction for computational analysis.
