0

Santos has started drilling the Dorado-2 appraisal well in WA-437-P offshore Western Australia.

Dorado is operated by Santos with Carnarvon Petroleum as a partner with a 20% interest.

Carnarvon Petroleum said the Noble Tom Prosser jack-up drilling rig had been mobilized from the Corvus-2 well location to the Dorado-2 well on April 26.

After arrival at the Dorado-2 location, located 2.2 km from the original Dorado-1 well, the rig had concluded the ready to operate process and had drilled the surface hole and installed the surface casing.

The rig will drill the 17 1/2” hole to the planned section depth of approximately 1,200 meters Measured Depth (MD) followed by setting the 13-3/8” casing.

Dorado-2 is the first appraisal well of the Dorado oil and gas field which was discovered in the latter half of last year. Dorado-1 discovered hydrocarbon bearing reservoirs in the Caley, Baxter, Crespin and Milne Members of the Lower Keraudren Formation.

The Dorado-2 well is located approximately 160 km north-northeast of Port Hedland in the Bedout Sub-basin.
