(1991 Code, sec. 22-64)
(a)
A blowout preventer, control head and other connections for keeping the well under control at all times shall be installed as soon as surfacing casing is set. The blowout preventer on the second string shall be hydraulically controlled. All control equipment shall be in good working order and condition at all times.

All wells shall be equipped with a bradenhead with a working pressure of not less than three thousand (3,000) pounds per square inch. The bradenhead shall not be welded, and the same shall be equipped with the proper pipe connection and valve accessible at the surface.
(1991 Code, sec. 22-66)
The casing program of all wells drilled in this field shall consist of at least two (2) strings of pipe set in accordance with the following program:
(1)
The surface casing shall consist of new or reconditioned pipe with an original mill test of not less than twelve hundred (1200) pounds per square inch, and shall be set and cemented in the first shale break below the base of the Trinity Fresh Water Sand, usually found in this area from nineteen hundred (1900) to twenty-two hundred (2200) feet or below. Cementing shall be by the pump and plug method, and sufficient cement shall be used to fill the annular space back of the pipe to the surface of the ground or the bottom of the cellar. Cement shall be allowed to stand a minimum of twelve (12) hours under pressure and a total of twenty-four (24) hours before initiating tests. Before drilling the plugs, a pump pressure of at least one thousand (1,000) pounds per square inch shall be applied. If at the end of thirty (30) minutes the pressure shows a drop of one hundred (100) pounds per square inch, or more, the casing shall be condemned. After the corrective operations the casing shall again be tested in the same manner, and this string shall stand the required tests before compliance with this rule shall have been made.
(2)
The producing or oil string shall consist of new or reconditioned pipe that has been tested to and has withstood the application of a pressure of at least twenty-one hundred (2100) pounds per square inch. Cementing shall be by the pump and plug method, and sufficient cement shall be used to fill the calculated annular space behind the pipe to a minimum of one thousand (1,000) feet above the guide shoe. Cement shall be allowed to stand a minimum of twelve (12) hours under pressure and a total of twenty-four (24) hours before initiating tests. Before drilling the plug, a pump pressure of at least fifteen hundred (1500) pounds per square inch shall be applied. If at the end of thirty (30) minutes the pressure shows a drop of one hundred (100) pounds per square inch, or more, the casing shall be condemned. After corrective operations, the casing shall again be tested in the same manner, and this string shall stand the required test before compliance with this rule shall have been made.
(1991 Code, sec. 22-67)
The operator of each well drilled within the watershed of the Trinity and Woodbine Sands affecting the source of the water supply of the city shall, before running the oil string in any well, furnish the city a true and correct electric log showing a true and correct electric picture of the well between the depths of twenty-five hundred (2500) feet and nineteen hundred (1900) feet from the surface of the ground, the same to be certified as being true and correct by a duly authorized representative of the electric log company performing such service, by a sworn statement to that effect.
(1991 Code, sec. 22-68)
No steam boilers will be permitted, unless the city council so authorizes at the hearing on the application for the permit, and then only on condition that boilers are located at least three hundred (300) feet from any dwelling, producing well, tank battery or separator.
(1991 Code, sec. 22-69)
Each person holding a permit for an oil or gas well under this article shall provide for safety stoves and vaporproof lights.
(1991 Code, sec. 22-70)
All operations under this article shall be conducted in such a manner as to assure that there will be no interference with or pollution of any of the sands or strata from which the water supply of the city or of any individual or corporation in the city is produced.
(1991 Code, sec. 22-71)
All permanent production tanks or flow tanks in the city limits shall be surrounded by a dike or ditch of at least the capacity of the tank.

(1991 Code, sec. 22-76)
(a)
All waste from an oil or gas well shall be disposed of in such a manner as to avoid creating a fire hazard or polluting streams or freshwater strata. No well, prior to its completion, shall ever be permitted to clean itself into an open pit, but the same shall be brought in flowing into a tank through a separator and the waste shall be disposed of outside of the city in such a manner as shall not constitute a nuisance.
(b)

(a)
It shall be unlawful to drill, dig, or excavate any well or hole of any size or type penetrating the first impervious stratum below the Trinity Sand at any location within the watershed or source of water supply of the city, unless surface casing is set into such first impervious stratum or shale body immediately below the lowest freshwater producing sands. As an alternative to the seat of the surface casing, oil and gas operators may set surface casing in the hard sand immediately below the shale break below the base of the Trinity Fresh Water Sand, and their report shall show whether the casing is set in the shale break or in the hard sand immediately below such shale break.
(b)
When any well or hole being drilled within the watershed or source of water supply of the city reaches the impervious stratum below the Trinity Sand, immediate notice of the reaching of such stratum shall be given to the city manager and an electric log of the well or hole to the bottom of such impervious stratum shall be given to the city manager, and no further drilling operations shall be conducted until the required casing has been set and cemented as required herein and a copy of the report or certificate of the cementing company has been furnished to the city manager.
(c)
All wells or holes and the drilling, digging, and excavating thereof below the impervious stratum below the Trinity Sand, which is the lowest known freshwater producing sand used by the city, without the setting and cementing of casing as required herein, are hereby individually and severally declared to be a nuisance, and further operations thereon may be enjoined on application of the city by any court having jurisdiction over such cases.
