The EIA publishes Annually a list of World Proved Reserves of Crude Oil. Though all charts in this post use the EIA data, BP, the IEA and virtually every other reporting agency in the world uses basically the same data. It is my contention that this data is misleading and totally meaningless. This is especially true of OPEC Middle East Reserves. However because this data is taken as gospel by the media and perhaps 90% of energy analysts in the world, this misinformation becomes a serious problem.
But first let's look at the data. It dates to 2014 in most cases but some data only goes to 2013. All data is billion barrels of reserves.
The EIA said we had 1,646 billion barrels of proved reserves in 2013. Other agencies put that figure a bit higher but we will go with this. And just where are these reserves located?
Almost half of the world's proved reserves are supposed to be located in the Middle East. Actually it would be well over 60% if it were not for the recent additions to world reserves by the Venezuela Bitumen and the Canadian Tar sands.

This is the proven reserves claimed by Canada and Venezuela. The EIA describes proved reserves as "reserves of crude oil which are with reasonable certainty to be recoverable." So Canada has 173 billion barrels of reserves and Venezuela 298 billion barrels of reserves that we can believe has "reasonable certainty to be recoverable? What does that mean?
As you can see Middle East proved reserves always increase, they never decrease no matter how much oil is pumped from those reserves every year. And the world's media accepts this nonsense without question. I once heard a reporter on CNBC point to the increase in world proved reserves in the decade of the 80s as proof that we are finding massive amounts of new oil all the time. No one bothered to point out that all this oil was found in board rooms by bureaucrats who simply "decided" this was how much oil they had.
Russia is the world's largest crude oil producer so we must look at her chart. (Not zero based.) Does this chart look realistic to anyone? This chart should prove to anyone that so-called proved reserves are simply set by bureaucrats with hardly any connection to actual reserves the country possesses.
Even the US has gotten in on the act, adding 11.5 billion barrels of proved reserves since 2009. They did not report US 2014 reserves. Most of this increase is light tight oil reserves but some reserves have been added to the Gulf of Mexico. Notice that this chart is not zero based.
I have changed the definition here to "claimed reserves" rather than "proved reserves" because everyone should know by now that the vast majority of those claimed reserves are a joke. So how much oil is left in the ground? I mean oil that can reasonably be recovered at a price that economies can afford to pay. I have no idea and I don't believe anyone else does either. But we can make an educated guess.
We must start by looking at reserves to production ratios. The RP ratio is expressed in "years of production at current production levels". An RP ratio of 25 would mean that a country has reserves of 25 times its current production. It does not mean that a country could produce at that level for 25 years then suddenly nothing. All reserves decline gradually. There are no hard and fast rules for RP ratios but in general we can say:
1. New fields have a higher RP ratio than old fields.
2. The larger the field the higher the RP ratio. Very large fields tend to produce higher for much longer than small fields.
3. The deeper the field the smaller the RP ratio. Very deep water fields have a very small RP ration.
4. Bitumen and tar sands have a very high RP ratio because their reserves can only be produced at a very slow rate.
5. Light tight oil is a completely different animal. Each well pumps from its own tiny reservoir. It is, or should be, totally independent from all other wells pumping from the formation. Each well would have a very small RP ratio but the RP ratio of the entire field, like the Bakken or Eagle Ford, would have a totally different RP ration from the entire field. Also, more than any other kind of reservoir, the RP ratio of an LTO field would depend on the price of oil.

All that being said we can say that the Middle East, because of its very large fields, should have a higher RP ratio than most other places in the world. But not that much higher. For instance the EIA claims OPEC has reserves of 1,206 billion barrels. OPEC produces about 11.7 billion barrels per year. That would give OPEC an RP ratio of about 103. Non-OPEC, on the other hand, the EIA says has 441 billion barrels of proved reserves. Non-OPEC nations produce about 16.28 billion barrels per year so that gives non-OPEC nations an RP ratio of about 27.
OPEC claims an RP ratio of 103, almost 4 times non-OPEC's 27. Actually the OPEC Web Site claims non-OPEC nations have only 284 billion barrels of proved reserves. That would give non-OPEC nations an RP ratio of only 17.5.
What can we believe? Well I can only speak for myself but I have always used the reasoning that nations, the vast majority of the time, produce every barrel they possibly can. And also that the more oil one has to produce the more oil they do produce. Therefore OPEC nations should have an RP ratio relatively close to that of non-OPEC, perhaps slightly higher because of their larger fields.
If OPEC has an RP ratio of 35 then that would give them reserves of 410 billion barrels.
If non-OPEC has an RP ratio of 25 then that would give them reserves of 407 billion barrels. And that would give the world about 817 billion barrels of recoverable reserves. I can accept that number. But that is my high pick. I could also accept a slightly smaller number.

I used the original reserve estimate to project global demand vs. production capacity (pre-fracking) and estimated the world would start bumping up against oil supply(cost)issues around 2005 (my personal est. for peak oil).
The main lesson learned is not to trust any public numbers from the enemy especially when they have announced very clearly they are at war...something we seem to take so lightly.
and we take the world oil consumption of 2014 (+\- 90 barrels)
it would only take us 25 years to totally run out of the stuff..
in the hypothetical-best case cuz you can't pump it all up.
We'll see
