Water-depth record set at well off India

Transocean Ltd. and Oil & Natural Gas Corp. have claimed a world water-depth record at a well offshore eastern India for drilling by a marine rig.

Transocean’s Dhirubhai Deepwater KG1 drillship spudded the ONGC NA7-1 exploratory well on Block KG-DWN-2004/1 on Jan. 23 in 10,385 ft of water. Since then the contractor has attached the blowout preventer to the wellhead to accommodate drilling to projected total depth of 5,625 m.

Transocean held the prior water-depth record of 10,194 ft for a well it drilled off eastern India in 2011 for Reliance Industries Ltd. with its Dhirubhai Deepwater KG 2 drillship.
