Nope, sorry, Norwegians actually tax mining / energy corporations (so the government has money to spend on... designer dunnies!), instead of just giving away their non-renewable natural resources to billionaires for free. That's un-Australian!

However, Saudi Arabia needs higher prices than Norway to balance the budget, so Saudi Arabia will likely cut first.
