New Delhi: Iran had agreed to buy the gas produced from ONGC Videsh Ltd-discovered Farzad-B field in the Persian Gulf, but talks got stalled after the US reimposed sanctions against Tehran.

During 2018-19, the National Iranian Oil Company (NIOC) proposed the development of the gas field and “offtake of raw gas by NIOC at landfall point(s),” it said. “However, due to imposition of US sanctions on Iran with effect from 5th November 2018, technical studies could not be concluded which is a precursor for commercial negotiations,” OVL said.
