A lease bond may be posted by a lessee, owner of operating rights (sublessee), or operator in an amount of not less than $10,000 for each lease conditioned upon compliance with all of the terms of the lease. Where 2 or more principals have interests in different formations or portions of the lease, separate bonds may be posted. The operator on the ground shall be covered by a bond in his/her own name as principal, or a bond in the name of the lessee or sublessee, provided that a consent of the surety, or the obligor in the case of a personal bond, to include the operator under the coverage of the bond is furnished to the Bureau office maintaining the bond.
