This refinery is nearly 1000km from the front line. So any drone, which can hit it, could also hit St Petersburg, Samara, Moscow and so forth. It is also a pretty small refinery. The one in Yaroslavl has 300,000 bbl/d, Nizhny Novgorod has 341,000 bbl/d, Samara has two one with 140,000 bbl/d and one with 164,000 bbl/d and there are lot more of that sort of size, which could all be hit by a drone like the one used here. Remember this one has 4,000 bbl/d, so much much less capacity.
Ukraine only has to take out the really large ones to cause a fuel crisis in Russia, which every Russian will feel. At least the ones living roughly in range of the drones. This however is a small refinery, so hitting it is not needed to cause a fuel crisis. This is what you hit, when you have the drones to hit it and want to cause some extra problems.
In other words. Ukraine has drones to spare, so they will very likely start to attack other targets such as the electricity grid in a massive way soon. That is a harder target, but they seem to have enough drones.
