A "marginal gas well," as applied to a well classified by the commission as a gas well, means a well that is incapable of producing under normal operating conditions more than 250,000 cubic feet of gas per day. None of the provisions of this chapter shall require the commission to limit the production from a marginal gas well to a quantity less than its actual deliverability if the well:
(1) has a daily deliverability of 100,000 cubic feet of gas or less; or
(2) is in a field for which special field rules are not in effect.
