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

Subsidence and thermal history models for 31 wells and 25 depocentre sites in the Browse Basin. The analysis examines the generation and expulsion history of Jurassic and Early Cretaceous petroleum systems, incorporating new palaeo-bathymetric estimates and kerogen kinetic data. The dataset was published by Geoscience Australia and last updated in April 2026.

Use Cases

• Modeling hydrocarbon expulsion timing and volumes based on subsidence and thermal history.
• Identifying effective source rock units for oil and gas charge based on modeled expulsion histories.
• Assessing exploration potential in specific sub-basins like the Heywood Graben and Seringapatam Sub-basin.
• Studying the impact of Late Tertiary carbonate clinoforms on fluid migration patterns.

Strengths

• Models incorporate data from 31 wells and 25 depocentre sites.
• Integrates new palaeo-bathymetric estimates and kerogen kinetic data for multiple source units.
• Analysis covers multiple petroleum systems (Jurassic and Early Cretaceous).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF and HTML formats, which may require extraction for computational analysis.
