According to EIA, world consumption will increase as follow:

2004 = 83 mbd

2015 = 97 mbd

2030 = 118 mbd

Table 4 list Gain & losses,  Saudi Arabia is described as having lost 1,2 billiion barrels but others countries have gain

the total of OPEC countries have nevetheless gained 95 billion barrels and non-Opec have gained 216 billion barrels

So the burden is not solely on SA

From 2004-2015, consumption should increased by 14 mbd which 8 mbd coming from Opec Countries and 6 mbd from non Opec.

From 2015-2030, world consumption is projected to increase by an additional 20 mbd which 15 mbd coming from Opec Countries and another 6 mbd coming from non Opec .

So, the increase from 2004-2030 is 35 mbd which 23 mbd from Opec and 12 mbd from non Opec. And this take in account losses form SA , according to what I've read in this report.

Now, whether the oil reserves of SA has been overevaluated, that I do not know.

There has been two different point of view, some say that world reserve are overevaluated, some say the contrary. Who is right, I dont know but I am optimistic person especially with all the other energy being developed( hydro, solar, wind, nuclear, hydrogen...)

All this do not solve Montello situation as to become a producer soon as money might be diffcult to get.

All the best
