State-owned Oil and Natural Gas Corp (ONGC) today said drilled a well in record water depths using a rig it had hired from Reliance Industries.
"ONGC's chartered-hired ultradeep water drillship DDKG1 has set a world record for drilling well in deepest water depth by an offshore drilling rig," the company said in a statement here.
The rig DDKG1 has spudded well NA7-1 in exploratory block KG-DWN-2004/1 in east coast India at a water depth of 3165 metres (10,385 feet) on January 23.
"Thereafter it successfully lowered and latched subsea (facilities) on February 09 to drill further to target depth 5625 metres," it said.
The rig owned by Transocean surpassed Transocean's own prior record of 10,194 feet of water depth, set in 2011 by DDKG2 working for Reliance Industries on the east coast.
