Ukraine seems to be the odd one out, this is not a surprise of course, but it could at least be good, they have the opportunity to buy the gas at the bargain rates.
Ukraine's reserves are probably that way because there's no way to get the gas there, no matter what the price is.
What do you mean? Ukraine produces a lot of gas and also receives gas from the EU via the eastern flow of the Yamal pipeline:
A lot of the replacement for Russian gas has been LNG imports. Ukraine doesn't have an LNG port as far as I'm aware, and if they did, I doubt it would be easy to get a ship safely there at the moment.
