The supervisor shall issue his order that such further tract or tracts of land insofar as they contain the pool or pools, or portions thereof, and the interests of all persons therein, upon recordation of such order in the office of the county recorder in each county in which any part of the original unit area or such additional tracts are situated, shall thereafter be subject to unit operations if he finds all of the following:

(a) All or a portion of such further tract or tracts of land do contain the pool or pools, or portions thereof, previously ordered unitized by the supervisor.

(b) The unit agreement has been consented to by persons who own title to working interests which aggregate at least an undivided three-fourths of the working interests in the total area proposed to be unitized, and by persons who own title to the royalty interest which aggregates at least an undivided three-fourths of the royalty interest in the total area proposed to be unitized.

(c) The addition of such further tract or tracts of land insofar as they contain the pool or pools to the unit operations is reasonably necessary in order to prevent waste or to increase the ultimate recovery of oil and gas.
