Members of the Organization of the Petroleum Exporting Countries (OPEC) should prepare for extra Iranian crude production when Western sanctions on Tehran are lifted, Iran’s oil minister was quoted on Tuesday by state news agency IRNA as saying. “We expect the members of OPEC to pave the ground for (an) increase of Iran’s oil production that will reach global markets when sanctions are lifted,” Bijan Namdar Zanganeh said during a meeting with his Venezuelan counterpart Asdrubal Chavez in Tehran, the agency reported.
