In 2006, following 35 years of declining
U.S. oil production, net monthly imports of crude oil and finished
products had climbed to more than 13 million barrels per day (BPD).
What's happened since is nothing short of amazing. Last week, the Energy Information Administration (EIA) reported that U.S. crude oil production had reached 10.38 million BPD.
This represents an increase of more than 1.2 million BPD in the past
year and is more than 5 million BPD higher than March 2006 production
levels.
U.S. crude oil demand has fluctuated a bit in recent years but
presently stands at just over 20 million BPD, which is about the same
level as in 2006.
Given the 10 million BPD difference between U.S. oil demand and U.S.
oil production, one might think that the U.S. is still dependent on
foreign countries for 50% of our crude oil. But it's more complicated
than that.
U.S. refineries have invested billions of dollars into equipment to
process heavy, sour (i.e., contains sulfur compounds) crudes. Most of
the new oil production in the U.S. is light and sweet, which isn't as
economically attractive for refiners who have invested in equipment to
process the lower grades (which are much cheaper).
Thus, U.S. oil producers have been exporting an increasing amount of oil, while U.S. refiners import the cheaper heavy grades. In just the past four years, U.S. crude oil exports have jumped from nearly nothing to more than 1.5 million BPD
(aided by a crude oil export ban repealed in December 2015):
