My thoughts on future areas getting Oil

There 3 countries that I expect to be the new Oil rush or even more.
*Nambia
*Guyana
*Surniname

Current possible countries going to expand Oil:

Bharain? They found a lot of oil but it also bit harder to get now

Current countries to be worried for":
Oman. They haven't found any new oil in awhile really. Small here and there but not great. Max 10-20 years of Oil/nat gas left for them.
