Oil and Gas Economic Opportunities 

  • July 22 Letter to Landowners - As owners of Indian trust lands on the Fort Berthold Indian Reservation (FBIR) you are in a   position to benefit on economic opportunities as oil and gas production develops

Notable accomplishments: Approved over 1,700 Oil and Gas leases and distributed over $80,000,000.00 in bonus payments. The Bakken formation is considered to be one of the largest oil producing formations in the lower 48 states. Strengths: We have developed staff expertise in Oil and Gas related activities. Challenges: We are now into the drilling phase of the Bakken Play and expect approximately 1000 wells to be drilled over the next 10 years. The environmental effects on the reservation will be substantial. The Agency staff when at full strength is 25 FTEs. This is counting 6 new positions added because of the mineral activity.
