The mineral estate is severed and dominant
Severance is the norm on Oklahoma ground, and the mineral estate is the dominant one — a mineral owner or lessee may make reasonable use of the surface to reach what is below. The Surface Damages Act, 52 O.S. §§ 318.2 to 318.9, softens that. Before entering a site to drill, an operator must ordinarily give the surface owner written notice of intent, and within five days of that notice both sides must begin good-faith negotiation over surface damages, with court-appointed appraisers if they cannot agree. It is a right to compensation, not a veto. A buyer prices the possibility of a pad site whether or not one is planned.
