Well this is curious, as supposedly Iran and S.A. hate each others’ guts, Islam-wise. One mostly Shiite, the other mostly Sunni. The cat marries the dog?
None of this makes sense. Iran and the Saudis are effectively at war. If the Saudis are in it that means Saudi Aramco is involved somehow. Does not compute.
The Marcellus Shale (2nd largest current gas play in the US) has an estimated 500 trillion cu ft of natural gas, which is also about 14 trillion cu M. The recoverable reserves though will be quite a bit less.
