Allocation of allowable production in field or pool.

A. Whenever, to prevent waste, the total allowable production of crude petroleum oil for any field or pool in the state is fixed by the oil conservation division in an amount less than that which the field or pool could produce if no restriction were imposed, the division shall prorate or distribute the allowable production among the producers in the field or pool upon a reasonable basis and recognizing correlative rights. B. Crude petroleum oil produced within the allowable as fixed by the oil conservation division shall herein be referred to as "legal oil" and crude petroleum oil produced in excess of the allowable shall be "illegal oil". C. Whenever, to prevent waste, the total allowable natural gas production from gas wells producing from any pool in this state is fixed by the oil conservation division in an amount less than that which the pool could produce if no restrictions were imposed, the division shall allocate the allowable production among the gas wells in the pool delivering to a gas transportation facility upon a reasonable basis and recognizing correlative rights and shall include in the proration schedule of the pool any well which it finds is being unreasonably discriminated against through denial of access to a gas transportation facility which is reasonably capable of handling the type of gas produced by that well. In protecting correlative rights, the division may give equitable consideration to acreage, pressure, open flow, porosity, permeability, deliverability and quality of the gas and to such other pertinent factors as may from time to time exist and, insofar as is practicable, shall prevent drainage between producing tracts in a pool which is not equalized by counter-drainage. In allocating production pursuant to the provisions of this subsection, the division shall fix proration periods of not less than six months. It shall, upon notice and hearing, determine reasonable market demand and make allocations of production during each proration period. Insofar as is feasible and practicable, gas wells having an allowable in a pool shall be regularly produced in proportion to their allowables in effect for the current proration period. Without approval of the division or one of its duly authorized agents, no natural gas well or pool shall be allowed to produce natural gas in excess of the allowable assigned to such source during any proration period; provided that during an emergency affecting a gas transportation facility, a gas well or pool having high deliverability into the facility under prevailing conditions may produce and deliver in excess of its allowable for the period of emergency, not exceeding ten days, without penalty. The division may order subsequent changes in allowables for wells and pools to make fair and reasonable adjustment for overage resulting from the emergency. The provisions of this subsection shall not apply to any wells or pools used for storage and withdrawal from storage of natural gas originally produced not in violation of the Oil and Gas Act [this article] or the rules, regulations or orders of the division. D. In fixing the allowable of a pool under Subsection C of this section, the oil conservation division shall consider nominations of purchasers but shall not be bound thereby and shall fix pool allowables to prevent unreasonable discrimination between pools served by the same gas transportation facility by a purchaser purchasing in more than one pool. E. Natural gas produced from gas wells within the allowable as determined as provided in Subsection C of this section shall be referred to in the Oil and Gas Act as "legal gas" and natural gas produced in excess of the allowable shall be referred to as "illegal gas".
