The major reason for production shortfall was delays in project implementation by ONGC and Cairn Energy

India missed oil and natural gas production targets by a wide margin due to fall in output at Reliance Industries' KG-D6 fields and delays in implementation of project by ONGC, according to Planning Commission. "Against crude oil production target of 206.73 million tonnes in 11th (Five Year) Plan period (2007-12), the anticipated achievement is 177 million tonnes, i.e. 14% below the target," the Plan Panel's draft note on Energy for the current 12th Five Year Plan period (2012-17) said.
