Carnarvon Petroleum Limited (ASX:CVN) will begin drilling the Dorado-3 well to further appraise the Dorado oil and gas discovery on WA’s North West Shelf after moving the rig to the well location this weekend.

Dorado-3 is the second appraisal well of the Dorado oil and gas field which was discovered in 2018.

This well will be drilled about 900 metres northwest of the Dorado-1 discovery location with the Noble Tom Prosser rig used in the previous Dorado-2 appraisal well.

The Dorado field is about 160 kilometres north-northeast of Port Hedland in the Bedout Sub-basin in water depth of around 95 metres.

Dorado and Roc oil and gas fields reside in WA-437-P in which Carnarvon holds a 20% interest with the remainder held by Santos Ltd (ASX:STO).

The Dorado-1 exploration well discovered hydrocarbon-bearing reservoirs in the Caley, Baxter, Crespin and Milne members of the Lower Keraudren Formation.

Dorado-2 appraisal well, around 2.2 kilometres northeast of the Dorado-1 well, confirmed hydrocarbon-bearing reservoirs in the Caley, Baxter and Milne members.

Importantly, it also demonstrated connectivity within each reservoir between the two wells.

The JV plans to conduct two, and potentially up to three, flow tests on Dorado-3 targeting the Caley, Baxter and Milne reservoirs, as well as acquire about 380 metres of full-bore core in these members as well as the Crespin Member.

This will result in a significant amount of new data to further characterise the Dorado field.
