I got some info through the grapevine that drilling is moving toward Wayne County. Trenton Formation, to be particular. I heard that a well came in in the Trenton, and was producing like gangbusters. If you're being offered low bonuses/royalties, you should consider waiting a year or two to see what happens. Of course, if they're offering a lease with great terms, it might be worth it to sign now. Just keep the primary term short -- one, two, or three years at most.
We should think about a landowners/mineral owners group for negotiating leases. People interested?
