Petroleum Systems Model Scenarios for the Vulcan Sub-basin, Offshore Western Australia

Several scenarios of a 3D petroleum systems model for the Vulcan Sub-basin were simulated using PetroMod software. The modeling results confirm prior work on generation timing and maturity, while incorporating new PhaseKinetic models for compositional predictions. The dataset is hosted by the Australian Ocean Data Network and was last updated in May 2026.

Use Cases

• Compare hydrocarbon generation timing and maturity predictions based on the different modeled scenarios.
• Evaluate exploration risk by analyzing predicted accumulation locations relative to proven fields.
• Assess the impact of model resolution on predicted accumulation sizes and column heights.
• Study the physical properties of accumulated fluids based on the distinct variations between scenarios.

Strengths

• Modeling results are compared to a prior published study (Fuji et al., 2004), providing a basis for validation.
• The description identifies specific exploration risks (source rock definition, trap definition, model resolution, cap rock properties) derived from the modeling exercise.
• Results include predictions for untested locations, which could guide future exploration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description notes the model resolution is low, which may affect the precision of accumulation predictions.
