Hydrocarbon Expulsion Models for Browse Basin Petroleum Systems

Browse Basin analysis of 31 wells and 25 depocentre sites models hydrocarbon generation and expulsion. The dataset incorporates new palaeo-bathymetric estimates and kerogen kinetic data for Jurassic and Early Cretaceous source units. Models suggest gas expulsion is widespread, while effective oil charge is largely restricted to the Heywood Graben and Serringapatam Sub-basin.

Use Cases

• Modeling hydrocarbon expulsion timing based on subsidence and thermal history analysis.
• Assessing source rock effectiveness for oil and gas charge based on kerogen kinetic data.
• Evaluating exploration potential in outboard areas based on the influence of Late Tertiary carbonate clinoforms.
• Calibrating regional petroleum system models with data from specific wells like Heywood-1 and Crux-1.

Strengths

• Analysis incorporates data from 31 wells and 25 depocentre sites.
• Models integrate 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 may reflect geographic bias inherent to the Browse Basin study area.
