A lease for production made by a personal representative may be made subject to the confirmation of the district court, for a period of not more than ten years, and it may be extended thereafter as long as oil or gas is produced from such land by the lessee or the lessee's assigns or the lessee or the lessee's assigns are engaged in continuous drilling or reworking operations. Such a lease must be made upon such terms and in consideration of such bonuses, royalties, rentals, and payments as may be agreed upon except that in no case may the royalty be:
No lease for production is effective for a period of more than two years from its date unless mining or a well is commenced on such land within such time, except that the lease may provide that the lessee may pay a delay rental in an amount that may be specified in the lease. Such payment operates as a rental and covers the privilege of deferring the commencement of mining or of a well for one year. A lease may provide for the payment of successive delay rentals which defers the commencement of mining or of a well for like successive periods. Any lease made by a personal representative under the authority of this section may provide for the pooling or unitization of the lease land, or any part or parts thereof, and of any mineral or royalty interest therein, with land adjoining or in the vicinity of the leased land, or any mineral or royalty interest therein, so as to form a unit for development and purpose of operation. Operations or production on any such unitized area shall have the same effect as operations or production on the leased land. The lease may provide for payment of a proportionate part of the royalties on production from any such unitized area to the personal representative in lieu of the royalties provided in the lease as to the area so unitized. A personal representative, upon compliance with the provisions of this chapter, may also enter into agreements pooling or unitizing existing leases. Upon the execution, approval, and delivery of a production lease, all persons interested in the estate are bound thereby during the entire period thereof.
