TEHRAN: Iran has claimed that its oil reserves have risen by nine percent to 150.31 billion barrels, partly driven by new discoveries.In a press conference, the Oil Minister Masoud Mirkazemi said Monday that Iran’s oil reserves were at present at 150.31 billion barrels as compared to the previous figure of 138.0 billion barrels.“Our calculations are still ongoing.
