Swiss-based drilling contractor Transocean says the drillship Dhirubai Deepwater KG2 has set a new world record for drilling depth, reaching 3,100 metres off India.
The offshore drilling rig, which is owned by a joint venture with Quantum Pacific Group, has been working for Reliance Industries off India’s coast for the past year under a five-year contract, Transocean said.
The vessel is equipped to work in water depths of up to 3,650 metres and outfitted to construct wells up to 10,600 metres deep.
Transocean is the world's largest offshore drilling contractor and the leading provider of drilling management services worldwide.
The Zug-based company owned the controversial Deepwater horizon oil rig, leased to BP, which was the source of the world’s largest oil spill in the Gulf of Mexico from April to July last year.
