Selling natural gas well with mineral rights

[Alex Scaffold]

So we bought land in marcellus shale decades ago....8yrs ago we got a lease agreement for a well for 5yrs - $GOOD DAY$....8yrs pass, shale is out of vogue in america for environmental and oil business/economic reasons.  Clearing was done, road built for well production, before pipes laid company ran out of $$ when oil price tumbled and shale production slowed in U.S.  Three years since lease expiration have passed, we would love to finance more realestate deals if we could sell the land for an approriate value........anyone in oil/gas biz?? - YEAH huge issue despite clearly there being minerals (our agreement was with a major natural resource company so this was not speculation per se).  Noticed a few oil field posts so figured i would see if any "oil men" or women visit here and would be good enough to share some insight on this unusual realestate question.  Any resources or links to land owner groups or investment groups who actually buy well land pre-drilling totally appreciated.  thanx for reading , have a good day.
