Oil pump jacks are seen along Interstate 94 in the Bakken Formation near Belfield, North Dakota in January 2017.<br /> <br /> The oil industry in North Dakota supports much of its economic stability and infrastructure. According to a recent study by Grand Forks firm AE2S Nexus, cities in North Dakota's oil-heavy Bakken Formation are expected to see a growth in population as oil prices recover. The population growth will require an expansion of city infrastructure and services to keep up with demands needed to provide for its residents.
