>Maybe, but who knows how much oil the SU had in reserves?

Fighting on reserves without supply is pretty good way to be defeated. Considering that Germany was somewhat close to winning in 41-42, it would be crucial.

>Also grabbing the land might not helped the Germans, that oil had to be extracted and refined to solve their shortage.

But Germans fought pretty well even with shortage. USSR, on other side, fought not so good in first years even with abundance of supply. So, even sitting there and doing nothing is a good way to remove USSR, and without USSR there is no one on continent who could stop Germans, especially if they wouldn't go into another radical blitzkrieg.

Although all these alternative history theories are hard to prove and could, of course, be countered by other theories.
