Reliance to hire Deepwater Millennium drillship

Vol 8, PW 13 (22 Sep 04) Exploration & Production

Reliance is talking to Transocean about using its ultra deepwater drillship Deepwater Millennium at KG-DWN-98/3.

Negotiations are in the final stages and barring any hiccup the drillship should begin drilling at KG-DWN-98/3 by the end of the year. Reliance wants to hire the drillship for at least a year with the possibility of a years extension.

Deepwater Millennium is a dynamically positioned fifth generation ultra deepwater drillship designed by Reading and Bates and built in 1999 by Samsung in South Korea. She is currently drilling in the deep waters of the Gulf of Mexico.

On her arrival in India, Deepwater Millennium will replace Transoceans deepwater drillship Discoverer 534, which is drilling for Reliance at KG-DWN-98/3. Once on location, Deepwater Millennium can begin exploring in the deeper parts of KG-DWN-98/3 that have so far eluded the company.

Deepwater Millennium can drill in maximum water depths of 2430 metres but this capability can be upgraded to 3000 metres. She can also drill to a maximum depth of 9144 metres below the seabed and - thanks to her 15,000-psi BOP stack can operate in the harsh drilling environment that confronts drillers on Indias eastern offshore.

Discoverer 534 is a moderate environment deepwater drillship built in 1975. It was last upgraded in 1996 and before that in 1991.

She can operate in maximum water depths of 2100 metres and drill to a maximum depth of 7925 metres. However, she only has a 10,000-psi BOP stack.

Discoverer 534 has been drilling for Reliance at KG-DWN-98/3 for more than two years now, since April 2002. Shes currently drilling her 13th well, which we believe was spudded in early August in water depths of 1530 metres.

Target depth of 3700 metres is expected sometime early October.
