$150 Billion in a decade? I would say there is considerable doubt.
If you want to look at some big numbers, check out what the Saudis are doing.
That link describes plans to spend a total of $29 billion. Why is that supposed to be more impressive than $150 billion? It is less than 20% of the Alberta projects.
You don’t seem to get it. The amount of money spent on those projects is new money. Do you have any comprehension what it takes to develop such a field. I lived in Saudi Arabia for five years and have seen those fields and other major projects. Believe it or not, $150 billion in the oil industry is not a lot of money.
