The commission may fix and determine the gas-oil ratio of all oil wells in the state but none of the provisions of this chapter may be construed to authorize the limitation of the production of marginal wells below the amount fixed by statute. If a restriction imposed by the commission on the production of oil from an oil well operates to increase the gas-oil ratio of the well so as to then classify it as a gas well under the provisions of this chapter, the well nevertheless shall be considered to be an oil well.
