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

The Vulcan Sub-basin offshore Western Australia is modeled using PetroMod 3D software to predict source rock transformation and petroleum fluid composition. The modeling results confirm prior work on generation timing and present-day maturity, while incorporating new PhaseKinetic models. The work was published by Geoscience Australia Data and was last updated on 2026-05-14.

Use Cases

• Predicting petroleum fluid bulk composition based on PhaseKinetic models for source rock formations.
• Assessing exploration risk by evaluating predicted accumulations dependent on fault closure.
• Comparing present-day maturity and generation rates between the Central Swan Graben and Cartier Trough kitchen areas.
• Validating trap and cap rock property definitions against model predictions of accumulation size and location.

Strengths

• Model results are validated against locations of most proven fields.
• Includes multiple scenarios showing distinct variations in petroleum distribution and fluid properties.
• Source rock transformation ratios and bulk generation rates indicate present-day generation activity.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The model resolution is described as low, affecting predicted accumulation sizes and column heights.
