ONGC sets world record in ultra-deepwater drilling

National oil and gas exploration and production company ONGC, a major operator in India’s deepwaters, has spudded a well at 10,411 ft of water depth. The well (# 1-D-1) in exploratory block KG-DWN-2005/1 off the country’s east coast is being drilled by rig DDKG1. This enabled ONGC to surpass its own earlier world record set in January 2013 for drilling a well in the deepest water depth.
Since 2004 ONGC has drilled over 100 deepwater wells. A large number of these are in water depths beyond 5,000 ft in environmentally and logistically difficult areas of India’s eastern and western

coasts, ranging from the Gujarat offshore to the Mahanadi offshore and including six wells in the Andaman offshore.Around 25 of these wells have been drilled at water depths of 5,000 to 7,500 feet and 16 at water depths of 7,500 to 10000 feet. The current world record well (# 1-D-1), which is under drilling, is the third well beyond 10,000 feet water depth.

It was in 1998 that ONGC upgraded its drillship Sagar Vijay from 1,000 feet to 3,000 feet water depth capacity to explore deepwater acreages.
