This isn't appropriate for this board. We have no idea. 200,000 is a lot of people for a "town". And since when do towns get "rich with oil money"? Is everybody in the town rich? Does that have anything to do with the question at all?
If the demand is there, it will be met, sooner or later.
I'm closing this because its just a speculative question and is outside the scope and guidelines of this board, PM me if you have any questions.
