The well has potential to produce 1 million to 2 million standard cubic metres per day (mscmd) of gas and the output is expected to stabilise by the middle of the month, the Reliance official said.
Reliance is currently producing about 10 mscmd gas from the KG D6 block, sharply lower from the 60 mscmd production at the end of 2010. Reliance and partner BP have cited geological complexities for the fall in output but the oil regulator believes they have failed to drill enough wells.
Falling output had already prompted the government to disallow proportionate cost recovery to Reliance, leading to arbitration proceedings over the issue.
Last month, govt allowed Reliance to charge higher prices for gas from April only after the company offered financial guarantees to the government to settle any claims against it over a shortfall in its gas output.
