Woah woah woah.
LS Crude is NOT FUEL. It's crude petroleum and there's a big difference between the two. Fuel has been refined.
When oil is refined its broken down into many usable parts.
Gasoline is cooked off (the first and easiest thing to refine out) but then the bitumen left has a billion uses. Everything from baby bumpers to vitamins. Refining towers are the most difficult to manufacture of all the parts of a refinery. It is the target when trying to destroy a refinery. (Not the storage tanks) Heating tubes and at different levels to extract the various parts of the bitumen. Lots of precision work.
Moldova's oil (no refineries) has more of the most expensive by products after the gasoline is cooked off. That's why their oil gets more per barrel than any other. I may be thinking of the wrong country's name. There are websites dedicated to which oil wells by area are at what price. So if you look up the various crude oil prices....you will see. West Africa, East Africa, Various places off the coast in South America as well as many many others. Lots of oil fields out there.
Things like benzene, sulphur, and etc are combustible but extremely toxic and unusable for much. These are usually produced when refining.
Refinery time is also at a premium anymore. There is a limit as to how much a refinery can produce without needing to shut down to replace seals and etc. (Heated petroleum products moving in steel causes static electricity sparks....leaks are deadly in this environment) Many refineries have gone way past production limits and paid the price for doing so by the complete destruction of the refinery.
(Petroleum is acidic in nature and will eat steel and seals)
LNG is fairly stable....not explosive as a liquid although it will burn. Turning it back into a gas is fairly simple process. More BTUs per cubic foot than propane or kerosene. (Just saying)
And finally Russian oil is usually cheaper than WTI or Brent.
