Bill,
Have any of the wells drilled in the immediate are started producing either oil or gas or both? Is this a proven field? If yes, this is going to help you drive up the price of your lease. Don't be in a hurry-there are probably other oil companies that would be interested in making you a fair offer. Not sure how things work in Ohio. Try to get a minimum of 25% royalty interest on your lease. BTDT in NM
