1985
From 1982 to 1985 OPEC attempted to set production quotas low enough to stabilze prices. Repeated failures occured because various members of OPEC would produce beyond their quotas. Saudi Arabia acted as the swing producer cutting its production to stem the free falling prices. In August of 1985 they tired of this role and linked their oil prices to the spot market and in early 1986 increased production from 2 MMBPD to 5 MMBPD.

1981
Events in Iran and Iraq led to another round of crude oil price increases in 1979 and 1980. The Iranian revolution resulted in the loss of 2 to 2.5 million barrels of oil per day between November of 1978 and June of 1979. In 1980 Iraq's crude oil production fell 2.7MMBPD and Iran's production by 600,000 barrels per day during the Iran/Iraq War. The combination of these two events resulted in crude oil prices more than doubling from $14 in 1978 to $35 per barrel in 1981.
