Geology has become fascinating to me. It started with a search for the oldest rock on earth (4 billion years in Canada), then learning about oil production (Bitcoin is going to monetize a lot of stranded hydrocarbons), then about the fascinatingly varied geology of California, and now I'm back to how it pertains to oil. Some quick facts from 2009:

Global oil use: 30 billion barrels of oil per year

World reserves: 830-4200 billion barrels

Total used so sar: 1050 billion barrels

So you can see we may be past peak or may not. I think it's unlikely and from a carbon perspective there's much more coal.

Globally we've had 40 years worth oil proven, a number that has held steady for the last couple decades, so it's like we have more if we want it.

Overall, the tech is very interesting from gravimetry to seismic imaging, but if there's one takeaway oil is going to be with us for many decades. I suspect that if we will get any sort of handle on climate change it'll be through capture tech, or delivering aerosols to the atmosphere, but probably not through the fantasy of coordinated abstinence from hydrocarbon use.
