Apparently upset over India not committing to invest in the ONGC-discovered field when Iran was under sanctions, the Persian Gulf nation remained non-committal on giving rights of the field to ONGC Videsh Ltd when a high level Indian delegation visited Tehran last month, sources said.
While the Indian side insists it is engaged with Iran on the issue, Iran's semi-official Fars News Agency last week reported that Tehran has withdrawn the offer for Farzad-B.
Indian officials, however, said they haven't heard anything from Tehran on the issue and the news report may be part of Iran's attempt to put pressure on ONGC to accept its terms. Tehran also wants India to raise oil imports.
"We continue to be engaged with Iran on the issue," an official said.

A delegation, headed by Ashutosh Jindal, Joint Secretary in Ministry of Petroleum and Natural Gas, held extensive talks with Iranian officials on development rights to the Farzad-B gas field in the Farsi block.
Indian firms have so far shied away from investing in Iran for the fear of being sanctioned by the US and Europe.
ONGC Videsh Ltd, the overseas arm of state-owned Oil and Natural Gas Corp, had in 2008 discovered the Farzad-B gas field in its Farsi exploration block in the Persian Gulf.
In August/September 2010, it submitted a revised Master Development Plan (MDP) for producing 60 per cent of the 21.68 trillion cubic feet of in-place gas reserves but had not signed the contract because of threat of being sanctioned by the US which is against any company investing more than USD 20 million in Iran's energy sector in any 12-month period.
For more than two years, it did not carry out the threat of cancelling allocation of the Farsi block to OVL.
To pressure India to act, Tehran last year put the field on the list of blocks it wants to auction in future, sources said, adding it has however not yet cancelled OVL's exploration licence for the Farsi block which gives it the right to develop the discoveries it has made.
