North Dakota Oil, Gas Mineral Rights worth nearly $3 billion

(Bismarck, ND) -- A Watford City-based company says North Dakota's oil and gas mineral rights are worth two-point-eight billion dollars.

The current value is 18-percent higher than last year's appraisal.

The valuations take into account current prices and natural declines in production.

Representatives from MineralTracker say the value could generate up to ten-billion dollars in royalties in the next several decades.
