The chart above shows the crude oil production in each US region as of January 2019 in thousands of barrels, the change from the previous month, and the production one year prior. The Northeast produces almost no crude at all.
- The difference between the region with the greatest production, the South, and the region with the least, the Northeast, is 174,934 thousand barrels (down from 177,354 last month and up from 143,850 last year). The South and the Northeast had the greatest and least production respectively both last month and last year.
- The South has 352.98 times the production that the Northeast does. The ratio of highest production to lowest production was down from 395.12 last month and up from 272.93 last year.
- Zero regions did not see a change in their crude production from the previous month, two produced more, and two regions produced less.
- Zero regions did not see a change in their crude production from last year, while three increased production, and one decreased production.
