Australian Ocean Data Network provides 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 models suggest multiple effective source units for gas expulsion and identify specific areas for oil charge.
Use Cases
- Model hydrocarbon expulsion timing based on subsidence and thermal history data
- Identify prospective areas for oil and gas exploration based on modelled expulsion volumes
- Assess source rock quality sensitivity for expulsion models in deepwater sub-basins
- Correlate modelled expulsion events with known hydrocarbon accumulations mentioned in the description
Strengths
- Analysis based on data from 31 wells and 25 depocentre sites
- Incorporates new palaeo-bathymetric estimates and kerogen kinetic data
- Models 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 may reflect geographic bias inherent to data_gov_au
