RE:Shale production has entered its twilight:NuttallIt happened a while ago. Shale oil is unsustainable without major cash injections. US Department of energy pumps helicopter money to several US shale producers under different back door deals to motivate the producers. They have been doing it for at least a decade. Watch for "weird" subsidies you read in the news how US government transfers billions of dollars to Oil companies under "Climate Change" agenda.

Spot price of oil for WTI, Brent and WCS has nothing to do with market but has to do with what US department of energy decides it will be.
