Browse Basin Hydrocarbon Expulsion Models from 31 Wells and 25 Depocentres

31 wells and 25 depocentre sites were analyzed for subsidence and thermal history to model hydrocarbon generation and expulsion in Australia's Browse Basin. The models incorporate new palaeo-bathymetric estimates and kerogen kinetic data for Jurassic and Early Cretaceous petroleum systems. This dataset was published by Geoscience Australia and last updated on 2026-03 25.

Use Cases

• Model hydrocarbon expulsion timing and volumes based on subsidence and thermal history data.
• Assess source rock effectiveness for oil and gas charge in different sub-basins like the Heywood Graben.
• Evaluate the impact of Late Tertiary carbonate clinoforms on fluid migration pathways.
• Correlate modelled expulsion histories with observed hydrocarbon accumulations like Cornea and Gwydion-1.

Strengths

• Analysis is based on data from 31 wells and 25 depocentre sites.
• Models incorporate new palaeo-bathymetric estimates and kerogen kinetic data.
• Results are linked to specific geological formations and known hydrocarbon accumulations.

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 data_gov_au.
