Why it matters: American production is part of the reason that recent efforts by OPEC — and its strategic ally, Russia — haven't been able to end the slide in global oil prices.
Economic weakness in China — the world's largest oil importer — is dampening demand and also playing a role in the price drop.
State of play: U.S. benchmark oil prices are down nearly 20% in the fourth quarter, to below $75 a barrel.
The national average price for a gallon of regular gasoline is $3.24, according to AAA. That's down 5% in the last month.
