Vulcan Sub-basin 3D Petroleum Systems Model with Fluid Composition Predictions

Offshore Western Australia's Vulcan Sub-basin is modeled using PetroMod 3D V.10 software. The dataset contains results from several scenarios of a 3D petroleum systems model, including source rock transformation ratios, bulk generation rates, and predicted fluid compositions and accumulations. The modeling was conducted by Geoscience Australia Data, with results last updated in 2026.

Use Cases

• Predicting hydrocarbon fluid composition based on PhaseKinetic models for source rocks.
• Assessing exploration risk by comparing predicted accumulation locations with proven fields.
• Evaluating source rock maturity and generation potential in different sub-basin kitchen areas.
• Analyzing the impact of model resolution on predicted accumulation sizes and column heights.

Strengths

• Model results are validated against the timing and maturity findings of a prior 2004 study.
• Includes predictions for untested locations, highlighting potential exploration targets.
• Provides distinct scenario variations for petroleum distribution and fluid properties.

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's low resolution is noted to influence predicted accumulation sizes.
