Unitization of Oil and Gas Fields and Pools
§ 53-3-109. Amendment of orders; extension of units and inclusion of additional pools

The State Oil and Gas Board, after notice and hearing, by entry of new or amending orders, may from time to time enlarge the unit area by approving agreements adding to the unit operation a pool or pools or any portion or portions or combinations thereof not theretofore included, and extensions of existing pools. Any such agreement, in providing for allocation of production from the unit area, shall first allocate to each pool or portion thereof so added a portion of the total production of oil or gas, or both, from all pools affected within the unit area, as enlarged, such allocation to be based on the relative contribution which such added pool or portion or extensions thereof are expected to make, during the remaining course of unit operations, to the total production of oil or gas, or both, to the unit as enlarged. 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. Orders promulgated under this paragraph shall become operative at 7:00 a.m. on the first day of the month next following the day on which the order becomes effective under the provisions of paragraph (b) of this section.
An order promulgated by the board under paragraph (a) of this section shall not become effective unless and until (1) all of the terms and provisions of the plan of unitization and the unitization agreement relating to the extension or enlargement of the unit area or to the addition of a pool or portions thereof or extensions of existing pools to unit operations have been fulfilled and satisfied and evidence thereof has been submitted to the board, and (2) the extension or addition effected by such order has been agreed to in writing by the owners or lessees of at least seventy-five percent (75%) in interest on the basis of and in proportion to the surface acreage content of the area or pools or portions thereof or extensions of existing pools to be added to the unit operation by such order and also by at least seventy-five percent (75%) (exclusive of royalty interests owned by lessees or by subsidiaries or successors in title of any lessee) in interest of the royalty owners on the basis of and in proportion to the surface acreage content in the area or pools or portions thereof or extensions of existing pools to be added to the unit operation by such order, and evidence thereof has been submitted to the board, and (3) the owners of the existing unit have agreed in the manner provided in Section 53-3-107 or in accordance with the terms of the unitization agreement, to the extension or addition. In the event all of the above requirements are not fulfilled within twelve months from and after the date of such order, it shall be automatically revoked.
After the operative date of an order promulgated under this section, costs and expenses of operation of the unit, as enlarged, shall be governed by paragraph (e) of Section 53-3-105. Adjustment among the owners of the unit area, as enlarged, (not including royalty owners) of their respective investments in wells, tanks, pumps, machinery, materials, equipment and other things and services of value attributable to the operation of the unit area, as enlarged, shall be governed by paragraph (d) of Section 53-3-105.
