Karoon Gas Australia said that the Zephyros-1 exploration well was spudded at 06:45 hours (WDT) on 12 November.
The Transocean Legend semi-submersible rig is drilling the exploration well, which is operated by ConocoPhillips.
ConocoPhillips is the operator of the jointly held WA-314-P, WA-315-P and WA-398-P Browse Basin permits containing the previously announced Poseidon and Kronos gas discoveries.
Karoon Gas Australia Ltd holds 40% of the permit WA-315-P and WA-398-P, and 90% of permit WA-314-P.
Zephyros-1 is the second well in the exploration program, and follows the recent, highly successful, Boreas-1 well.
Zephyros-1 is located in permit WA-398-P on the flank of a large tilted fault block approximately 9 kilometres southwest of the Kronos-1 discovery well. The objective of the Zephyros- 1 well is to test the extent, presence and quality of Plover formation reservoirs.
