Buddy,
A non-drillsite UMO has no right to unilaterally ratify a unit and claim his share of production. An NPRI owner is treated differently if their interest is covered by an existing lease. The lease in and of itself is an offer to the NPRI owner to pool, and the NPRI owner therefore has the right to ratify the lease and any unit the lease is pooled into. If on the other hand, the NPRI owner's interest is not covered by a lease, he is an unleased interest and has no unilateral right to ratify a unit.
