Tithonian Play Assessment for Dampier Sub-Basin and Rankin Trend

A quantitative assessment of the hydrocarbon potential in the Tithonian play of the Dampier Sub-basin and Rankin Trend, offshore Western Australia. The analysis includes data from six drilled wells and uses Monte Carlo simulation to evaluate four undrilled prospects. The dataset was published by Geoscience Australia Data and was last updated on 2026-04-30.

Use Cases

• Estimate undiscovered hydrocarbon resources based on Monte Carlo simulation results.
• Compare the performance of drilled wells like Angel and Egret against undrilled prospects.
• Model geological risk and uncertainty for prospects such as Courtenay, Wallcot, Nickol, and Finucane.
• Support regional exploration strategy in the Dampier Sub-basin based on the quantitative appraisal.

Strengths

• Assessment includes data from six real-world drilled wells, including the significant Angel gas and Egret oil discoveries.
• Uses a quantitative, prospect-by-prospect evaluation method with Monte Carlo simulation.
• Focuses on a defined geological play (Tithonian) in a specific region (Dampier Sub-basin and Rankin Trend).

Limitations

• Row count and specific column-level documentation are unknown, limiting suitability assessment.
• Data is presented in PDF and HTML formats, which may require extraction for computational analysis.
• The description does not specify the exact time range of the underlying geological data or the simulation parameters.
