1. Russia is a petrostate and much of the real economy is derived from providing services to the oil/gas sector.
2. Oil/gas export revenues have been hit hard this year from low oil prices and a strong rubble.
3. There are already fuel shortages in the country.
Smacking oil refineries over and over again exaggerates these problems and deprives the Kremlin of money to pay for the war, which as they love to point out, is fought by voluntary contract soldiers.
If money runs out for the Kremlin then those contracts aren't going to be as lucrative nor attractive because they can't afford it and then Russia must either mobilise or withdraw.
