They can't get the oil, because there are not any (additional) pipelines. They can't really ship the oil, because there's not enough (additional) capacity to do that. Most tankers can't get insured and only smaller tankers can transit ports available to Russia (or they have to transfer oil mid ocean). As a result Turkey, India, and China will get marginally more 10-30% cheaper oil from Russia, but that pushes their imports from the middle east down... which lowers prices in Europe!

Realistically, Turkey China and India are mostly exporters. When Europe and the US go into recession, they won't need as much oil because they won't be exporting as much (they are the dominant importers)... and that likely means that Russia turns off wells when their storage fills up (soon). Those wells are slow to restart. The rest of OPEC replaces their oil (at somewhat higher prices) for the next few years.

What is an immediate concern is food, oil, and fertilizer not being exported from Ukraine (can't plant/harvest or ship) for much of the developing world. Turkey, Egypt, Sri Lanka... Sudan are all very dependent on wheat, sunflower oil, and fertilizer from eastern Ukraine. Even India will be quite affected. See how evil EU starves the poor! Only beautiful Russia can save them!
