The oil reserves in Saudi Arabia are estimated 188 million barrels, equal to 37 days of Abqaiq’s oil production. Saudi oil reserves had a bearish trend since 2016.
It is worth noting that some reports published by western companies including Rapidan in recent months remarked the significance of Abqaiq as the biggest oil field worldwide. Even they wrote that the close of Strait of Hormuz by Iran can stop oil trade for several days but any potential attack to Abqaiq plant can limit oil production for several months!!!
