On January 23, the ultradeep water drillship DDKG1 spudded well NA7-1 in exploratory block KG-DWN-2004/1 in east coast India at a water depth of 3165 metre (10,385 feet), state-owned Oil and Natural Gas Corp (ONGC) informed.
With this, ONGC set a world record for drilling well in deepest water depth by an offshore drilling rig, the firm said in a statement.
“Thereafter it successfully lowered and latched subsea (facilities) on February 09 to drill further to target depth 5,625 metre,” it said.
It may be noted that ONGC hired the rig from Reliance Industries (RIL). 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.
