8. "Unit" means the total area of land that results from the combining of interests in all or parts of two or more leases or fee interests in order to operate the reservoir as a single production unit subject to a single operating interest. A unit may be formed by an agreement between the mineral interest owners (voluntary unitization) or by order of an agency of the state or federal government (compulsory unitization). A unit does not include "poolings" resulting from the enforcement of spacing requirements. This definition is only effective for periods prior to April 27, 1987.
