It depends on which side of the coin your on. When all the work was here for methane, it was a Sellers market. The prices were high due to the demand. Now that the work has dropped off it is a Buyers market and the prices have dropped about 20-30,000 on most the properties if not more. As far as owning a place with methane , some that had old mineral rights made out like bandits I think. Others had their well dry up.
I know of some old ranches that the methane allowed them to get things and pay off loans that they probably couldnt before. Others lost their good water supplies though. When Wyoming loses its good ground water what do you have left? Some were getting 60,000 a month in mineral royalties or higher while oters were getting only surface damage rights and payments. This is all just my opinion though Hope this helps
