There are dozens of ways to increase production through world peace, better drilling technology and ideological conversion. Most of African production is well below geological potential (Libya being the easiest example, but also applies to Nigeria and the DRC etc). European shale is barely investigated, Russia is restricted by sanctions, the Middle East by war. Antartica and the Falklands are relatively unexplored but feasible.
However, the electrification of transport will erode demand in everything besides heavy shipping and jet fuel. Without that demand oil prices will crater.
Not sure I buy that. Oil will still be in demand as a chemical feedstock. In fact, there are already people saying that oil is too precious to use as a fuel.
If we have plenty of energy anyway we can just make exactly what we need, no need to drill for a mix of pot luck hydrocarbons. If we don't have enough energy anyway then we're burning hydrocarbons to get energy and we might as well use them as a feedstock too.
Substitution is highly impractical in the short term but in a conversations of decades/centuries it's significant. Venezuela's reserves alone could run the world's petrochemicals for 60 years (Gemini) so it's a realistic perspective. Together with other proven reserves we could be okay for centuries.
Recycling is sometimes an option too.
That's to say, I think you forgot to update your number when time passed.
1 - time started at the 1970s, that's a well known fact
