'Being new to the group, I have some learning to do. I am selling my surface land and retaining all mineral rights. I want to allow the buyer to have rights for a gas well for his home use and to share half of the royalties if any from that well. I understand that the deep well/shale drilling production does not present gas useable for surface owner use. If that is correct, would limiting drilling to a shallow well level for his purposes affect my right to deep well gas leasing? Also, if no well is drilled on the surface property but gas is drawn from horizontal legs, I understand that royalties for that gas taken from adjacent property is not paid on a metered basis but on a percentage of acreage included in the rectangular drilling space. Am I correct? If someone would enlighten me , I would be appreciative. Thanks..'.
