Wyoming Statutes Title 36. State Lands § 36-6-104. Payment for improvements; “improvements” defined

If mineral lands upon which improvements have been made shall be sold or if such lands shall be leased to other than the owner of the improvements thereon, then such purchaser or such new lessee shall pay to the owner thereof the value of said improvements, at an agreed price with the owner thereof; or if such agreement cannot be reached, then at such price as shall be fixed by appraisement under the authority of the board of land commissioners. The word “improvements” shall be construed to mean surface improvements, machinery and other equipment used and necessary for the operation of the plant on such land, and work performed in the development of the property for operation and mining when such development work is of practical use in future mineral operations on such land. Wells drilled for oil which do not produce oil in commercial quantities, shafts, tunnels or drifts from which coal or other minerals have been practically exhausted, shall not be considered as improvements.
