Mar. 2013 - Exploration drilling at the Proteus prospect is underway in license WA-398-P off Western Australia. Proteus-1 is the third well in the current five-well drilling campaign using the Transocean Legend (mid-water semisub) and follows the Zephyros discovery in the same license. ConocoPhillips, operator of WA-398-P, and its partner Karoon Gas Australia plan to use the rig throughout 2013 in an effort to determine the size and quality of oil accumulations in the Greater Poseidon trend.

Mar. 2013 - In a recent update concerning Zephyros-1, Karoon announced plans to begin coring operations after encountering a drilling break in the exploration well. Upon completion of coring activities, drilling will continue to the proposed total depth of 17,618 feet. The Transocean Legend (mid-water semisub) is drilling the well which is operated by ConocoPhillips. Zephyros-1 is located in WA-398-P and is the second well in the company's current exploration program, which consists of a minimum of five wells. Once Zephyros-1 operations are complete, the rig will mobilize to the Proteus prospect in the same license.

Jun. 2012 - ConocoPhillips is moving forward with drilling of the Boreas-1 exploratory well in WA-314-P following the final function testing of the blowout preventers for the semisub Transocean Legend (mid-water semisub). The BOPs and marine riser were run to the sea floor, and after function testing, were pulled from the hole for further repair and maintenance. After passing all checks on the surface, they have been re-run to the seafloor for final subsea function testing. The company will drill the second well in the program, Zephyros-1, in permit WA-398-P approximately 4.9 miles (8 kilometers) southwest of the Kronos-1 discovery location. The third well, Proteus-1, will be drilled in WA-398-P approximately 8.6 miles (14 kilometers) southeast of the Poseidon-1 discovery location.
