Considering how well the predictions on future price swings on crude oil have been realized, this is just a little more effort to create buzz, but nothing concrete.
The price of oil will stabilize at somewhat above the cost of production of the majority of the resources from where it is recovered.
If that is by fracking, then the cost of fracking plus maybe 5-10%. If by thermal depolymerization, then probably by the same margins. If by the dry reforming of methane into liquid hydrocarbons, depends on the supply of the feedstock methane, and the requirements of the final composition of the fuel desired, again along the same margins.
The world shall NEVER run out of hydrocarbon mixtures commonly known as kerogen or crude oil.
Nope, it will eventually become uneconomical and we will move on to something else. The stone age didn't end because we ran out of stones, or bronze, or iron, etc...
