No permit to drill or operate a well hereafter granted by the city under terms of any drilling ordinance shall be deemed to grant a vested right, but each such permit shall provide that it is issued subject to all future amendments of this chapter and all other ordinances or regulations that may be adopted hereafter by the city, to all future laws adopted by the state, and to all regulations adopted by the Railroad Commission of Texas; and that violation of any of same shall, when determined, after five (5) days' notice and hearing by the City Council be grounds for cancellation of any such permit, and operations thereunder shall cease immediately as of the time of such cancellation so made by the City Council.
