The board shall issue an order requiring such unit operation if it finds that:
(1) Unit operation of the field or of any pool or pools or of any portion of a pool or combinations thereof within the field is reasonably necessary to prevent waste, to increase the ultimate recovery of oil or gas, to avoid the drilling of unnecessary wells, to allow the drilling of wells at optimum geologic locations, and to protect the correlative rights of interested parties.
(2) The proposed plan for unit operations will increase the ultimate recovery of oil or gas by enhanced recovery methods or any other method of cooperative development and operation calculated to increase the ultimate recovery of oil or gas.
(3) The estimated additional cost incident to conduction of such operation will not exceed the value of the estimated additional recovery of oil or gas.
