I guess its useless to tell you that Ukraine is actually oil poor and that the whole oil thing is a western meme. Russian propaganda is that there is lots of oil in the region.
see April 26, 2022 War in Ukraine.
As far as all the other natural resources go, the Russian have them in abundance - including oil. So that whole thing is just a misdirection for the things that are important for Russia:
1) securing the fresh water supply to the Crimea,
2) more warm water ports on the Black Sea,
3) blocking the invasion route that goes through southern Ukraine and up to the Urals.
Everything else is just either made up, a misdirection or political BS. IMHO
I suppose the people to ask were the American oil companies with signed contracts to explore and exploit, they left in 2014 when Russia invaded.
So “I guess its useless to tell you” that you are pushing BS.
