My heart goes out to the families who stand to lose their homes in the oil fires in Alberta.
I can't imagine their horror, we used to see the water bombers flying out to British Columbia from Lac La Biche. A forest fire is one thing, you can try to contain it and create firebreaks to stop it.
These are worse than the rig and oil fires that Red Adair used to tap. Being tar fields, by their chemical makeup they'll retain the heat far longer than a normal fire.
You see the drills on TV http://www.history.co.uk/shows/ice-road-truckers and you don't realise how big they are until you see one for real - some I saw were wider than a body and longer than an NFL pitch - it took two trailers to carry the drills.
On a similar topic, the film Silent Hill https://en.wikipedia.org/wiki/Silent_Hill_(film) is based on a real town in Pennsylvania http://www.centraliapa.org/ where the coal seam caught fire over 40 years ago, the seam is giving off poisonous gasses and the town had to be evacuated. Experts say the seam won't burn out for 250 years, the heat is so intense a nearby seam is now ablaze and another town had to be evacuated.
