Oil and Natural Gas Corp (ONGC) had in 2007 farmed out 15 per cent stake in the KG-DWN-98/2 block, which sits next to Reliance Industries' KG-D6 block, to Brazil's state-controlled oil firm Petroleo Brasileiro SA or Petrobras. Another 10 per cent interest was given to Norway's Norsk Hydro (now Statoil Hydro).
The two firm, who are among the biggest deepsea developers in the world, were to bring in technology and expertise to development of gas discoveries in KG-DWN-98/2 or KG-D5 block of ONGC.
Frustrated at delays, the two firms finally walked out of the block in 2010.
KG-D5 block was originally planned to start producing gas from 2014 with a peak of about 20-25 million standard cubic meters per day. Now, the block will not produce before 2018.

After the pullout of Petrobras and Statoil, ONGC, which does not have the technology to produce gas from deepsea in geologically hostile KG basin, tried to rope in other foreign energy majors but its attempts were frustrated as it could not get approvals, sources said.
Shortly after the pullout by Petrobras and Statoil in 2010, the then ONGC Chairman R S Sharma had shot off an angry letter to the oil secretary saying red tape was making international oil majors apprehensive over sharing exploration risks in acreages where they pick up stake.
"This was done by ONGC as a part of its strategy to capitalise on the technological experience of international companies of repute in the development of deepwater discoveries," Sharma wrote.
