Sell or keep my mineral rights in Burke County

Supposedly, drilling is expected to start within the next 12 months. But who really knows, for sure. Can’t decide whether to seek a fair price for my mineral rights or wait it out. Anyone have an idea what “fair market value” currently is for the area, near Portal, ND? Or better yet, what the potential can be if the wells are not a bust? Around home here, in Weld County, CO, there are offers of $8000-$10,000 per acre. Further west, in the $20,000 area, which is kinda hard to believe.
