In the interest of conservation of oil and gas and the prevention of waste, the commissioner of public lands may consent to and approve the development or operation of state lands under agreements made by lessees of oil and gas leases thereon, jointly or severally with other oil and gas lessees of state lands or with oil and gas lessees of the United States or oil and gas lessees or mineral owners of privately owned or fee lands or oil and gas lessees of tribal or allotted Indian lands for the purpose of pooling or communitizing such lands to form a proration unit or portion thereof or well spacing unit pursuant to any order, rule or regulation of the New Mexico oil conservation commission where such agreement provides for the allocation of the production of oil or gas from such pooled or communitized area on an acreage or other basis found by the commissioner to be fair and equitable, and when such agreement is so approved, the drilling or operation of a well on any part of the area included in such agreement shall be considered as being drilled or operated on each tract included in such agreement, and the production of oil or gas in paying quantities from any part of such pooled or communitized area shall, for all purposes, be considered the same as if such production had been obtained upon each tract or separate lease included in such agreement. Upon approval of any such agreement, the lease or leases covering state lands committed thereto shall thereupon be amended to conform to such agreement.
