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.
"We deny the claim of apparent 'theft' of gas from (ONGC's) G4 and KG-DWN-98/2 Block by RIL and can only attribute it to the likelihood of some elements in ONGC misleading the new Chairman and Managing Director, Sarraf, in order to hide their own failure to develop discoveries made over the last 13 years in these blocks," RIL said in a statement.
Sarraf had on May 20 stated that ONGC had sued RIL to protest its commercial interest.
ONGC believes that RIL's D6-A5, D6-A9 and D6-A13 wells drilled close to the block boundary may be draining gas from its G-4 field of Godavari block while the well D6-B8 may be draining gas from DWN-D-1 field of its KG-DWN-98/2 block.

RIL said it has since August 2013, when ONGC approached it over the issue, been engaged with ONGC in the process of appointing an independent agency to investigate possible reservoir connectivity across the blocks.
It was decided to issue the Enquiry Notice on May 26.
"Since the process for appointing this agency as per international practice was already well underway it is indeed unfortunate that some elements in ONGC forced invocation of the Delhi High Court at this juncture.
"Resolution of such complex techno-commercial matters, that are not un-common in the oil and gas industry, is best done through the help of experts rather than public posturing. In any case, ONGC already having already filed a petition in the Hon'ble Delhi High Court, we would have expected greater restraint in a matter that has been made sub-judice by them," RIL said.
"As per our data, some of the resources is common to our block and RIL. There is apprehension that some of wells (of RIL) on the boundary of the block may be drawing gas from our fields," Sarraf had said on May 20.
