If Aramco has a hard time breaking even at $45 per barrel, they sure as hell will not break even at even $10 a barrel. Only an idiot would believe such a fairy tale. But, believe it if you want. The facts do not lie.
Probably close to $10. The spread between WTI and Brent (which doesn't have WTI's current storage issue) is usually around $10... and it's $19.33.
