According to the U.S. Energy Information Administration, ““Despite increasing crude oil prices throughout most of 2016, total U.S. crude oil production in 2016 was below its 2015 level. However, monthly production began growing in the fourth quarter of the year after declining over the first three quarters. Total 2016 production remained above the five-year average. With the removal of restrictions on exports of domestically produced crude oil at the end of 2015, crude oil exports increased. At the same time, the difference between Brent and West Texas Intermediate (WTI) crude oil prices narrowed, which made crude oil imports relatively more attractive and caused total imports of crude oil in 2016 to also increase.”
