ONGC had on May 15 moved the Delhi High Court alleging that RIL may have drawn natural gas worth thousands of crores of rupees from its fields that sit next to Mukesh Ambani-run firm's KG-D6 block Krishna Godavari basin.
"It is shocking to note that motivated interpretation of the whole episode is floated and wild allegations against ONGC are being hurled by vested interest with the intention to derail the whole rightful approach of ONGC," Sen wrote to Pradhan today.
"By analyzing relevant data and other materials, ONGC found that some of RIL's wells drilled adjacent to the block boundary have been drawing gas from its (ONGC) field and hence chose to sue RIL in order to protect its commercial interest and natural resources of the country," he wrote.
Denying ONGC charges, RIL had in a May 23 statement claimed that there was "likelihood of some elements in ONGC misleading the new Chairman and Managing Director, DK Sarraf, in order to hide their own failure to develop discoveries made over the last 13 years".
RIL had stated that ONGC was yet to commence development of any of the discoveries in its two blocks.
