Hydrocarbon Expulsion Models for Browse Basin Petroleum Systems

Subsidence and thermal history analysis of 31 wells and 25 depocentre sites examines Jurassic and Early Cretaceous petroleum systems in the Browse Basin. The models incorporate new palaeo-bathymetric estimates and kerogen kinetic data to assess generation and expulsion history. This work was published by the Australian Ocean Data Network and the record was last updated in April 2026.

Use Cases

• Model hydrocarbon expulsion timing from Jurassic Plover and Lower Vulcan formations using subsidence and thermal history data.
• Assess the sensitivity of oil expulsion in the Seringapatam Sub-basin to organic richness and quality features of Jurassic rift sediments.
• Evaluate the charge potential of the Early Cretaceous Echuca Shoals Formation petroleum system using sequence stratigraphic models.
• Analyze the impact of Late Tertiary carbonate clinoform geometries on fluid migration pathways using modelled compaction waves.

Strengths

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

Limitations

• Primary data format is PDF/HTML, requiring manual extraction for quantitative analysis.
• Sample data and underlying raw measurements are unavailable.
• Models are specific to the Browse Basin, limiting direct application to other regions.
