Russian inflation sums up the damage to Russian economy. The damage to refineries might drive inflation higher. Especially if Russian farming has less fuel.
Fuel shortages to the Russian army might not be significant if most of Russian war machines are not replaced.,
The damage to oil infrastructure would include frozen oil if pipelines are damaged. I have not seen any reports on this just coverage of damage to oil pumping stations.
I am wondering if the recovery of oil production will take months, years or decades.
