Santos’ Dorado-2 appraisal well confirmed oil and gas in the Bedout Basin offshore Western Australia. The well, approximately 2 km from the Dorado-1 discovery, encountered 85 m of net reservoir in the primary Caley formation. An oil-water contact was intersected at 4003 m MD, with 40 m of net oil pay. An additional 11 m of pay was encountered in the Upper Caley sands, and 32 m of net pay was encountered in the underlying Baxter and Milne sandstones. Initial indications show compositions similar to the light oils and gases sampled in Dorado-1. High-quality reservoirs and fluids and the shallow-water setting should facilitate cost efficiency and add value. Santos is the operator of the permit with an 80% stake; Carnarvon Petroleum owns 20%.
