Only about 2% of crude oil consumption is for "petrochemical feed-stock", which includes, among other things, plastics production:
(There's also a significant percentage of crude consumed in the refinery process [the heating required for the distillation] - about 5% loss there IIRC.)
I.e. over 90% of crude oil consumption is for various forms of transportation and heating purposes, which will be easily replaced with renewables - and of the remaining 10%, half of it (5% of the total) is dirty stuff but doesn't get combusted and doesn't go into the atmosphere.
I.e. only about ~5% of crude oil consumption is a CO2 emissions source that is harder to replace with renewables.
Obviously reducing world oil consumption by a factor of ~10, which would collapse oil prices to somewhere around $20 per barrel and would render 90% of the crude oil extraction sites uneconomical, and would cut the total value of crude oil reserves, crude extraction and distribution infrastructure from over 100 trillion dollars to well below 1 trillion dollars is not where the oil industry wants to go ...
At the top of the list of large oil companies who don't want to go there is the one named "Russia".
