Drilling Activity in Kingfisher County

I have some mineral rights in Sec 21-T17N-R08W. I would like to know if any drilling is occurring in this area? At the present time the mineral rights are leased to Newfield Exploration.

Also,I have received an offer to buy the mineral rights. I would like to know what price or prices would be considered in the ballpark? Any thoughts would be appreciated. Joe Edson

how much is the offer?
