I do not believe that Alberta’s reserves are so low. I think the criteria employed must not be including anticipated reserves that are not yet exploited. I also don’t believe that Venezuela has more oil than Saudi Arabia.
Let’s see. If we have 45 billion barrels underground at 20 million barrels a day of consumption we can supply ourselves for 3000 days-that’s what-10 years? Soon 20 million barrels per day won’t be enough-think AI. Then what? Seems like all of the above is the answer.
I think that might be correct.
The issue...
Venezuela oil is the most costly to refine in the entire world.
High sulfur content, as I recall.
I grew up in south Florida.
In the 1950s and 1960s, we used to burn un-refined Venezuela oil to generate electricity!
