(a) The Commission may limit the total amount of oil, including condensate, which may be produced in the State by fixing an amount which shall be designated "allowable" for the State. The Commission may then allocate or distribute the "allowable" for the State among the pools on a reasonable basis and in such manner as to avoid undue discrimination, and so that waste will be prevented. In allocating the "allowable" for the State, and in fixing "allowables" for pools producing oil or hydrocarbons forming condensate, or both oil and such hydrocarbons, the Commission may take into account the producing conditions and other relevant facts with respect to such pools, including the separate needs for oil, gas and condensate, and may formulate rules setting forth standards or a program for the distribution of the "allowable" for the State, and distribute the "allowable" for the State in accordance with such standards or program, and where conditions in one pool or area are substantially similar to those in another pool or area, then the same standards or programs shall be applied to such pools and areas so that as far as practicable a uniform program will be followed; provided, however, the Commission shall allow the production of a sufficient amount of natural gas from any pool to supply adequately the reasonable market demand for such gas for light and fuel purposes if such production can be obtained without waste, and the condensate "allowable" for such pool shall not be less than the total amount of condensate produced or obtained in connection with the production of the gas "allowable" for light and fuel purposes, and provided further that, if the amount allocated to pool as its share of the "allowable" for the State is in excess of the amount which the pool should produce to prevent waste, then the Commission shall fix the "allowable" for the pool so that waste will be prevented. In allocating "allowables" to pools, the Commission shall not be bound by nominations or desires of purchasers to purchase oil from particular fields or areas, and the Commission shall allocate the "allowable" for the State in such manner as will prevent undue discrimination against any pool or area in favor of another or others which would result from selective buying or nominating by purchasers of oil, as such term "selective buying or nominating" is understood in the oil business.
