I assume you are talking about easily extractable oil. That is getting harder to find without extreme technology. You used to be able to find oil in Pennsylvania/Texas/California by waking around with high heels. These days you would want a map of Saudi Arabian oil fields that are known but not tapped. Drilling there will still produce shallow wells that produce gushers.
