High-tech drillship for Aust waters

High-tech drillship for Aust waters The latest in deepwater drilling technology will be on show later this year with the arrival in Australian waters of GlobalSantaFe's Glomar Jack Ryan drillship, up for hire at a shade under half a million Australian dollars per day.

The vessel is being brought in to drill at least four wells and another handful of wells are looking likely prospects if scheduling, day rates and other oilfield factors come together.

The vessel is being brought from the US and after a seven week mobilisation will be charging around US$200,000 - 210,000 per day, if industry sources are correct, for its work around the Carnarvon Basin and the Great Australian Bight.

At this stage, the Jansz NE-1 well in WA-268P, belonging to ExxonMobil and ChevronTexaco (50% each), is the first well, followed by Wigmore-1 in WA-295P (Kerr McGee and Agip - 50% each).

A consortium of BHP Billiton / ChevronTexaco and Kerr McGee (33% each) have earmarked the vessel for a well in permit WA-302P before it moves to the Great Australian Bight to drill in EPP-29 for Woodside (40%), Anadarko and EnCana (30% each).

The vessel may drill more wells in that region if negotiations pan out before returning to the NW Shelf, with weather conditions playing a major part in any drilling activities in the turbulent Bight.
