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:
U.S. crude oil exports.
But
the U.S. also exports finished products like gasoline and diesel. In
fact, a growing fraction of the oil being consumed in the U.S. is simply
being refined and exported. In 2011, the U.S. became a net exporter of
finished products (e.g., diesel, gasoline, etc.) for the first time
since 1949. Finished product exports have continued to grow since:
Net finished petroleum product exports.
Note that this graphic reflects the difference between the finished products we import and those we export.
When
all the factors are considered, the impact of growing U.S. oil
production becomes clear. The overall balance between U.S. imports and
exports of both crude oil and finished products fell to 2.6 million BPD
in December. That is the lowest level since the EIA began tracking this
category in 1973:
Net imports of petroleum and petroleum products.
Last fall the International Energy Agency declared in its World Energy Outlook 2017
that the U.S. could be a net exporter of oil within a decade. On the
current trajectory, net imports could indeed turn into net exports in
2020.
Incidentally, 2020 is also the last year that the IEA projects
that supply growth will keep up with demand growth — given the present
level of global investments. I will address that possibility in the next
column.
