in it he makes the point that a working refinery would be helpful at time
like this.

Refined oil, ie diesel, petrol and jet fuel can only be stored for about 70 days before it is not fit for purpose. Sludge builds up from the micro organisms growing in the tank. However cruel oil can be stored for much
longer. So with a refinery one can storge many months worth of oil and
refine it when needed.
