American oil producers list their shirts so badly it took 3 years sky rocket oil prices to convince them start drilling again.

They respond as rational actors in the market.
As for the Arctic, if the Russians were anticipating ice free conditions in the near future, think again. If planning to work a ocean field with ice in place, more expensive to get and deliver. They would need technical assistance.
The OPEC guys import the majority of their base food staples from those importing oil. So far, no one is applying this leverage. ISIS has compromised the indigenous farming operations... expect shortages there if not famine.
