Before drilling and setting casing in any well for oil or gas within the city limits, the permittee must contact the city manager or his designee and the state board of water engineers and obtain letters stating where the fresh water sands are to be found in the area or field in which the well is to be drilled. A copy of the state board of water engineers' letter must be filed with the city secretary and the permittee must set sufficient surface casing as required. Failure to file a copy of the state board of water engineers' letter shall be unlawful and shall be punishable as such. Sec. 21-39. Permitted hours for delivery or removal of material, equipment, etc. Material, equipment, tools or pipe used for either drilling or producing operations at the well shall not be delivered to or removed from the well site except between the hours of 9:00 a.m. and 5:00 p.m. of any day, except in case of emergency. 10 Sec. 21-40. Derrick and rig. It shall be unlawful for any person to use or operate, in connection with the drilling or reworking of any well within the city limits, any wooden derrick or steam powered rig, or to permit any drilling rig or derrick to remain on the premises or drilling site for a period longer than sixty (60) days after completion or abandonment of the well. All engines shall be equipped with effective mufflers. Where reasonably possible, an electrical rig shall be used. Tripping operations shall not be conducted between the hours of 10:00 p.m. and 7:00 a.m., except in emergency situa- tions. In the event of an emergency, the City Manager shall be notified immediately. Sec. 21-41. Drilling fluid. No well shall be drilled or re -worked in the city without the bore hole at all times being filled with drilling fluid of such weight and viscosity as a reasonably prudent operator would use to keep the well under control at all times. Sec. 21-42. Swabbing operations and drill stem tests. It shall be unlawful for any person, in connection with the drilling or re -working operations of any well within the city, to conduct any swabbing operations or to take and to complete any drill stem test except during daylight hours. Drill stem tests may be conducted only if the well effluent during the test is produced through an adequate oil and gas separator to storage tanks, and the effluent remaining in the drill pipe at the time the tool is closed is flushed to the surface by circulating drilling fluid down the annulus and up the drill pipe. Sec. 21-43. Casing. (a) The operator of any well within the city shall be required to set and cement a sufficient amount of surface casing to properly protect all fresh water sands as specified by the state board of water engineers and the city manager or his designee. The surface casing shall be of new or reconditioned casing and shall be set and cemented in accordance with the rules, regulations and orders of the state railroad commission for the field or area in which the well is to be drilled. Cementing shall be by the pump and plug method and sufficient cement shall be used to fill the calculated annular space back of the casing to the surface of the ground and the cement shall be allowed to stand for a period of twelve (12) hours before drilling plug. (b) In lieu of setting the full amount of surface casing required to protect fresh water sands, the permittee may use the multi -stage cementing process. In using the multi -stage cementing process, sufficient cement shall be used in the stage cement job 11 that is equivalent to the volume of the annulus from the cementing tool to the surface of the ground. Should the cement not reach the surface of the ground, a temperature survey must be conducted and if the survey shows that the top of the cement is less than one- third of the distance from the shoe of the surface casing to the surface, then corrective measures must be taken. Any permittee using the multi -stage process must file with the city secretary a copy of the state railroad commission letter granting such permit and an affidavit from the company performing the cementing. Failure to file either of these shall be unlawful and shall be punishable as such. (c) In any well drilled within the city, the producing string of casing shall be of new or reconditioned pipe which has been tested and withstood the maximum anticipated pressures to be encountered. Cementing shall be by the pump and plug method and sufficient cement shall be used to fill the calculated annular space back of the casing to a point at least six hundred (600) feet above the shoe or the highest productive zone, whichever is applicable, and the cement shall be allowed to stand for a period of twelve (12) hours before drilling plug. After cementing, the casing shall be tested at a pressure in pounds per square inch calculated by multiplying the length of the producing string by two -tenths (0.2), being the maximum test pressure required. If at the end of thirty (30) minutes the pressure shows a drop of ten (10) percent or more of the above required test pressure, the casing shall be condemned. After corrective operation, the casing shall again be tested in the same manner. Sec. 21-44. Blowout preventers. Two (2) dual controlled, fluid operated blowout preventers with working pressures equal to the maximum anticipated wellhead pressures shall be used for all drilling or completion operations involving the use of drill pipe or tubing after the surface casing has been set. The mechanical operation of the preventers shall be checked every twenty-four (24) hours and shall be tested with pump pressure with enough frequency to insure good working order at all times. Sec. 21-45. Christmas tree fittings and wellhead connections. All completed wells within the city shall be equipped with Christmas tree fittings and wellhead connections, with a rated working pressure equal to or greater than the surface shut-in pressure of the well. All wellhead connections shall be assembled or tested prior to installation by a fluid pressure which shall be equal to the test pressure of the fitting employed. 12 Sec. 21-46. Flaring and burning of escaping gas. No person engaged in drilling or operating any well shall permit gas to escape or be vented into the air unless such gas is flared and burned. All gas flared or burned from a torch, pipe or other burning device within the city must be done in such manner so as not to constitute a fire hazard to any property, and the location of the torch, pipe or other burning device and the construction, maintenance and operation thereof shall at all times be in full compliance with such regulations as may from time to time be issued by the fire marshal of the city. Sec. 21-47. Disposal of salt water and other impurities. Any person drilling or operating a well for oil or gas shall make adequate provisions for the disposal of salt water or other impurities which may be produced along with the oil or gas in such a manner as not to contaminate the water supply of the city or destroy vegetation or otherwise adversely affect the environment. Sec. 21-48. Escape of waste matter onto adjoining property prohibited. It shall be unlawful for any person to permit to escape any mud, water, oil, slush or other waste matter related to the drilling or operating of any oil or gas well into any adjoining lots, blocks or tracts upon which the permittee does not have leases or other contractual rights to use the surface, or into the alleys, streets, gutters or sewers of the city. Sec. 21-49. Slush tanks for mud or water. Only portable steel slush tanks for mud or water shall be permitted in connection with the drilling and re -working operations of any well. Sec. 21-50. Crude oil storage tanks; separators; etc. It shall be unlawful for any person to use, construct or operate in connection with any producing well within the city limits any crude oil storage tanks except to the extent of two (2) steel tanks for oil storage, not exceeding five hundred -barrel capacity each, and so constructed and maintained as to be vapor tight and each surrounding with an earthen fire wall at such distance from the tanks as will, under any circumstances, hold and retain at least one and one-half (1-1/2) times the maximum capacity of such tank. A permittee may use, construct and operate a steel conventional separator, and such other steel tanks and appurtenances as are necessary for treating oil with each of such facilities to be so constructed and maintained as to be vapor tight. Each oil and gas separator shall be equipped with both regulation pressure relief safety valve and a bursting head. At 13 the request of the city manager or his designee, such tanks shall be located underground and shall be appropriately landscaped so that they are not visible from the surrounding area. Sec. 21-51. Equipment for secondary recovery, pressure maintenance or automatic lease operations. Any person may install equipment for the purpose of secondary recovery or pressure maintenance operations or for automatic lease operations provided such person complies with all safety requirements of this chapter and of the state railroad commission. Sec. 21-52. Fired vessel or open flame prohibited near well or storage tank. It shall be unlawful for any person with the city limits to install any fired vessel or open flame nearer than one hundred fifty (150) feet to any well or storage tank. Sec. 21-53. Fencing. All wellheads, tank batteries, pumping units and equipment appurtenant thereto within the city, which are located within a densely populated area or nearer than five hundred (500) feet to a public street shall be adequately protected by a fence so constructed that it will prevent easy entry. Any wellhead, tank battery, pumping units or equipment appurtenant thereto which is located on any lease, tract or farm, which is fenced in its entirety, will require no additional protection other than that commonly used by prudent operators. Fences to prevent easy entry shall be approved by the city manager or his designee. Sec. 21-54. Maintenance of premises.
