If you subscribe to the theory that all crude comes from organic matter that is crushed, heated and puterified for a long time, don’t you wonder if there are ancient micro-organisms lurking in it?
When you take a crude sample offshore, don’t you worry that the mist that comes of the collection container hasn’t seen the light of day for millions of years, and the last time it did it was a living organism?
Petrol, not too worried, it’s gone through a distillation tower, the heat should kill off those little critters.
Makes you want to wear a mask all the time, don’t it?
