MilGov may also have sent troops to non-functional refineries to salvage surviving difficult-to-manufacture parts to then transport to refineries that were more intact and/or were in better locations in terms of transport hubs, ability to be protected etc.

Also as has been mentioned in other discussions over the years, the Soviets' targeting systems were notoriously unreliable, and as the war progressed their ability to perform post-strike reconnaissance became more difficult or impossible, so some facilities like refineries may have been damaged by near-misses but not obliterated. If the Soviets couldn't get eyes-on but noted through other means that fuel production had dropped, they might assume the job was done. But in reality some refineries may have been put out of commission temporarily but been intact enough to have been brought back into production later, particularly if critical parts could be salvaged from elsewhere and the EMP-affected electronics could be repaired, replaced or bypassed.
