Offshore oil drilling group Transocean claimed Tuesday that it had a set a world record for deep water drilling at an ocean depth of 3,107 metres (10,194 feet) off the coast of India.

The depth was achieved by the ultra-deepwater drillship Dhirubhai Deepwater KG2, surpassing the previous record of 10,011 feet, also set by Transocean in 2003 in the Gulf of Mexico, the group said in a statement.

It set "what the company believes is a world record for the deepest water depth by an offshore drilling rig of 10,194 feet of water while working for Reliance Industries offshore India."

Transocean owned the BP-leased Deepwater Horizon rig that exploded last year in the , killing 11 rig workers and triggering a huge spill along the southern US coast.

The disaster also highlighted the growing exploitation of hard to reach and costly fields beneath on the , driven by dwindling resources and higher oil prices.

By comparison North Sea fields have been largely exploited at water depths of around 100 metres.

3,107 meters as compared to 100 meters? I hate to be a paranoid, but that(w/o considering pressure et al) means there is 30 times more pipe that is subject to failure. Not to mention the chance of unleashing all those weird Hindu gods.
