100,000 barrels are burned uncontrolled, but the pipeline is shut down for 10 days. Does burning that 100,000 cause more emissions than is saved by slowing down 10 million barrels of production from the wells that have nowhere to put the oil?
Most of that 10m barrels of consumption will find a way to have it produced somewhere. So emissions is in addition to the fire+repairs. Price disruption due to event will encourage more drilling, and once something is drilled with support infrastructure, it is easily profitable to keep sucking instead of stop sucking, even if fewer use oil
