| Since 2010, production in the Bakken has generally increased [[:file:Figure1Bakken2019-20CommRpt.jpg|Figure 1]], with notable declines beginning in 2014 ([[:file:Figure2Bakken2019-20CommRpt.jpg|Figure 2]]) due to a drop in oil prices and in mid-2020 due to the decrease in demand during in the ongoing COVID-19 pandemic. Overall, oil production has remained high, and North Dakota continues to be the second largest oil producing state in the country (https://www.minneapolisfed.org/region-and-community/bakken). | | Since 2010, production in the Bakken has generally increased [[:file:Figure1Bakken2019-20CommRpt.jpg|Figure 1]], with notable declines beginning in 2014 ([[:file:Figure2Bakken2019-20CommRpt.jpg|Figure 2]]) due to a drop in oil prices and in mid-2020 due to the decrease in demand during in the ongoing COVID-19 pandemic.
