The fact that there is a significant natural resource under the ground will only be an encouragement for non-Turkish majorities to want out of the Ottoman Empire - seeing all that money flow to Istanbul and very little return. At the very least, local bigwigs will want to get their share of baksheesh. If any of these bits are still under Ottoman control by the 1930s, I don't think anyone would be surprised if certain powers supported "autonomy" for these regions, and naturally these autonomous regions would now cut new deals about oil.
