Vulcan Sub-basin 3D Petroleum System Model with Source Rock and Fluid Predictions

Several 3D model scenarios simulate petroleum generation and fluid composition in the Vulcan Sub-basin, offshore Western Australia. The modeling results confirm earlier work on generation timing and maturity but incorporate new PhaseKinetic models for source rock formations. This dataset, from Geoscience Australia, includes predictions on source rock transformation ratios, bulk generation rates, and untested accumulation locations.

Use Cases

• Predicting hydrocarbon fluid composition based on PhaseKinetic models for source rocks.
• Assessing present-day source rock maturity and generation rates in different kitchen areas.
• Evaluating exploration risk by comparing predicted accumulation locations with proven fields and untested fault closures.
• Analyzing variations in petroleum distribution and fluid properties across different modeled scenarios.

Strengths

• Modeling results are validated against a prior published petroleum systems model (Fuji et al., 2004).
• Predictions include specific geographic areas like the Central Swan Graben and Cartier Trough.
• The dataset explicitly identifies key exploration risks based on the modeling exercise.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes low model resolution can lead to large predicted accumulation sizes.
• Row count is unknown, which may limit suitability assessment.
