The production so allocated to each added pool or portion thereof shall be allocated to the separately owned tracts in the added unit area on the basis of the relative contribution of each such tract, as provided in paragraph (c) of Section 53-3-105. The remaining portion of unit production shall be allocated among the separately owned tracts within the previously established unit area in the manner provided by the unitization agreement.
