An Assessment of the Tithonian Play in the Dampier Sub-Basin and Rankin Trend, Offshore Western Australia

Updated: 2026-07-23

The hydrocarbon potential of the Tithonian play in the Dampier Sub-basin has been rapidly assessed as part of a continuing program of quantitative appraisal of Australia's hydrocarbon potential. Six wells have already tested the play; of these Angel was a significant gas discovery and Egret was a significant oil discovery. The remaining potential in four undrilled prospects (Courtenay, Wallcot, Nickol, and Finucane) has been assessed by the prospect by prospect method, using a Monte Carlo simulation computer program called SIMULAT.
