It doesn’t make much sense to hit the pipelines if the refining infrastructure is broken. In that case they don’t have anything to send through the pipelines anymore anyway.

For oil yes, of course. But for gas it’s my understanding that it’s processed closer to the extraction sites, so it might not necessarily be in reach (yet). Although it seems like Ukraine just hit a gas processing plant in Orenburg a few days ago.

If Ukraine can extend their reach to 2500-3000km then they could probably reach most gas processing plants.
