Egypt doesn't have much of it, certainly when compared with Saudi Arabia and Iraq, and that's important to keep in mind when contemplating a post-Mubarak economy. From Nate Silver:
Nor is it true for some of the other countries in the region that are experiencing political tension. Yemen, for instance -- although its oil exports constitute a relatively large share of its G.D.P. because its economy is so underdeveloped otherwise -- earns only about $350 per capita per year from its oil exports. Syria, whose authoritarian regime is said to be nervous about the developments in Egypt, makes about $200 per head, as does Sudan, which is about to split in two. And Jordan has no oil exports at all. If the theory holds, then governments like these -- and not oil-rich ones like Libya, Algeria, or the states of the Arabian Peninsula -- are more likely to be the next to fall.
