Carnarvon Petroleum Limited (ASX:CVN) and joint venture partner Santos Ltd (ASX:STO) expect to begin the well test of the primary Caley oil reservoir from Dorado-3 well in the Dorado JV project during the coming week.
This will be the second well test from the Dorado-3 appraisal well after the first test of Baxter reservoir returned multi-rate flow test and pressure build-up results that exceeded expectations.
Second appraisal well
Dorado-3 is the second appraisal of the Dorado oil and gas field which was discovered in 2018.
The field is about 160 kilometres north-northeast of Port Hedland in the Bedout Sub-basin in around 95 metres water depth.
It resides in WA-437-P in which Carnarvon holds a 20% interest.
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 Dorado-1, confirmed hydrocarbon-bearing reservoirs in Caley, Baxter and Milne reservoirs and demonstrated connectivity within each reservoir between the two wells.
Further data for JV
The Dorado-3 appraisal well is about 900 metres northwest of the Dorado-1 discovery location.
This well has been designed to enhance the joint venture’s confidence in the subsurface
characteristics and confirm reservoir productivity.
The JV planned to carry out two flow tests targeting the Caley and Baxter reservoirs, as well as acquiring full-bore core in the Caley, Baxter, Crespin and Milne members.
This will result in a significant amount of new data to further characterise the Dorado field.
