By contrast, the US added about three million barrels per day in three years ('12,'13,'14).
Most of the oil price damage was caused by the dollar. Oil had been running at significant global oversupply for years before the dollar began to crash the price back in June/July 2014. That same dollar effect threw Canada into a recession, cut Australia's growth rate in half, and crushed emerging markets including Brazil.
Long before Saudi Arabia boosted production, the dollar took off on its greatest run in decades. Oil immediately began to crash from there forward.
The USSR also collapsed due to the strong dollar 30 years ago, which dropped the price of oil substantially. Oil went from $140 inflation adjusted, for three years, to plunging off a cliff to $35 or so, courtesy of Volcker's strong dollar move. And then again Russia nearly imploded during the cheap oil days of 1997-2000, also caused by an extremely strong dollar (gold hit around ~$250).
