TEHRAN -- Russians will soon start “executive operations” on developing two oil fields in Iran, Managing Director of the National Iranian Oil Company (NIOC) Mohsen Khojastehmehr has said. He made the announcement on the sidelines of Iran Oil Show, an international oil, gas, refining and petrochemical exhibition, which opened in Tehran on Friday. Khojastehmehr did not give further details. Since the January visit to Moscow by President Ebrahim Raeisi who was accompanied by a number of oil executives, there has been speculation about the participation of Russian companies in Iran’s oil projects.
