I look forward to port crude loading facilities (and pipelines to them) being targeted in a big way as well, significantly cutting revenues for the government from crude exports.
It will be interesting to see if Ukraine will target the pipelines during winter. It is a well known fact that Russian oil is very heavy and extracted from deep down at high temperatures. In order to be transported through pipelines, it must be kept in motion by using high pressure at all the times. If the oil stops flowing through the pipelines, it cools down and becomes almost solid, clogging the pipelines.
If a pipeline is blown during winter time, the oil will cool down instantly and clog the pipelines, which will be impossible to repair during winter conditions. Once a pipeline stays idle during winter, it is almost impossible to repair afterwards. If Ukraine manages to blow up Russian pipelines during winter, they might be taken out for good.
It is a well known fact that after the collapse of the USSR, many pipelines were idled for a while, and they got damaged because of that. In order to repair and restart them, Russia needed help from Western specialists, and it took more than a year to fix them, with all the Western technology available.
If a pipeline stays idle during winter now, there will be no more Western help to repair and restart it, so it will be ruined for good.
I am sure Ukrainian strategists know that as well, and they may have some very nice surprises in stock for the Russians udring winter. If they blow up the pipelines, the entire Russian oil industry will be in ruin.
