(a) If all of the mineral estate is conveyed to a regional corporation, the regional corporation will assume the lessor's obligation to administer any oil and gas lease.

(b) If a conveyance of the mineral estate does not include all of the land covered by an oil and gas lease, the lease will be segregated into two leases, one of which will cover only the mineral estate conveyed. The regional corporation will assume administration of the lease covering the conveyed mineral estate.

(c) If the regional corporation assumes administration of a lease under paragraph (a) or (b) of this section, all lease terms, BLM regulations, and BLM orders in effect on the date of assumption continue to apply to the lessee under the lease. All such obligations will be enforceable by the regional corporation as the lessor until the lease terminates.

(d) In a case in which a conveyance of a mineral estate described in paragraph (b) of this section does not include all of the land covered by the oil and gas lease, the owner of the mineral estate in any particular portion of the land covered by the lease is entitled to all of the revenues reserved under the lease as to that portion including all of the royalty payable with respect to oil or gas produced from or allocated to that portion.
