NAC 534A.260 Requirements for casing; alternate requirements for surface casing; exception for certain thermal gradient wells. (NRS 513.063, 534A.090)

1. Except as otherwise provided in subsection 2:

(a) All wells must be cased in such a manner as to minimize damage to the environment, ground and surface waters, geothermal resources and property.

(b) Except as otherwise ordered by the Administrator, the completion equipment for a well must be attached to the surface casing. All casing, except conductor casing, which reaches the surface must provide adequate anchorage for equipment for the prevention of a blowout and control of the pressure in the well.

(1) Provide for the control of formation fluids and protection of fresh water. The cement for the surface casing must be circulated up the annulus to the surface. If the cement does not circulate or falls back, the casing must be cemented at the surface. Sufficient casing must be set to reach a depth below all known or reasonably estimated levels of fresh water to protect those aquifers and to prevent blowouts or uncontrolled flows.

(2) Be cemented to a depth that is at least 10 percent of the proposed total depth of the well, with a minimum of 200 feet and a maximum of 1,500 feet of casing.

(3) If the first string of surface casing has not been cemented in a competent geological formation or if an unusual drilling hazard exists, include a second string of surface casing that is cemented into or through a competent geological formation.

(d) When intermediate casing is installed, cement must be circulated to the surface or to the top of the casing with at least a 100-foot overlap into the next string of casing.

(e) Production casing may be set above or through the production or injection zone. Casing must be cemented to the surface or, if a liner is used, to the top of the casing. If surface casing overlaps into an intermediate string, the overlap must be at least 100 feet, solidly cemented and tested to withstand at least 750 pounds of differential pressure per square inch of gauge. A decline in the pressure of 10 percent or less at the surface in 30 minutes is acceptable. For geothermal domestic wells less pressure or another acceptable mechanical test may be approved by the Administrator.

(f) For wells with downhole centralizers, casing strings must be properly centered and the top of the casing must be properly centered with the drilling rig during and immediately after the casing is cemented into place. The number and depth of the casing centralizer must be recorded in the well driller’s log during the installation of the casing strings.

(g) If a cellar is utilized, the design of the cellar must:

(1) Prohibit any contact between soil and water and the casing and wellhead components; and

(2) Prevent the occurrence of standing water around the casing and wellhead components.

2. The Administrator may:

(a) Impose alternate requirements for the surface casing of a well than those provided in paragraph (c) of subsection 1 to ensure that there is adequate protection of fresh water zones and blowout control. In considering whether to impose additional or alternate surface casing requirements, the Administrator may consider, without limitation, the known geological conditions of the area in which the well is drilled and any applicable engineering factors.

(b) Grant an exception to the requirements of this section for a thermal gradient well that is less than 500 feet deep.

2. Equipment for the prevention of a blowout, capable of shutting in the well during any operation, must be installed on the surface casing and maintained in good operating condition at all times. This equipment must have a rating for pressure greater than the maximum anticipated pressure at the wellhead. Equipment for the prevention of a blowout is required on any well where temperatures may exceed 200°F.

3. An operator shall test the equipment for the prevention of a blowout under pressure. A representative of the Division must observe the test in person or otherwise approve the results of the test before the operator drills the casing shoe out of the casing. An operator shall notify the Division not less than 24 hours before conducting a test pursuant to this subsection.

4.

NAC 534A.490 Abandonment of geothermal production, injection or observation well. (NRS 513.063, 534A.090) For abandonment of a geothermal production, injection or observation well, the following provisions apply:

1. Cement used to plug the well, except cement used for surface plugging, must be placed in the well bore by pumping through drill pipe or tubing. The cement must consist of a mix which resists high temperatures.

2. Cement plugs must be placed in the uncased portion of wells to protect all subsurface resources. These plugs must extend a minimum of 100 lineal feet above the producing formations and 100 lineal feet below the producing formations or to the total depth drilled, whichever is less. Cement plugs must be placed to isolate formations and to protect the fluids in those formations from interzonal migration.

3. Where there is an open well bore, a cement plug must be placed in the deepest casing string by:

(a) Placing a cement plug across the guide shoe extending a minimum of 100 lineal feet above and below the guide shoe, or to the total depth drilled, whichever is less; or

(b) Setting a cement retainer with effective control of back pressure approximately 100 lineal feet above the guide shoe, with at least 200 lineal feet of cement below, or to the total depth drilled, whichever is less, and 100 lineal feet of cement above the retainer.

4. If there is a loss of drilling fluids into the formation or such a loss is anticipated or if the well has been drilled with air or another gaseous substance, a permanent bridge plug must be set at the casing shoe and capped with a minimum of 200 lineal feet of cement.

5. A cement plug must be placed across perforations, extending 100 lineal feet below, or to the total depth drilled, whichever is less, and 100 lineal feet above the perforations. When a cement retainer is used to squeeze cement into or across the perforations, the retainer must be set a minimum of 100 lineal feet above the perforations. Where the casing contains perforations at or below debris or collapsed casing, which prevents cleaning, a cement retainer must be set at least 100 lineal feet above that point, and cement must be squeezed in the interval below the retainer.

6. The approval of the Administrator must be obtained before casing is cut and recovered. A cement plug must be placed in such a manner as to isolate all uncased intervals and guide shoes that are not protected by an inner string of casing. The plug must extend a minimum of 50 feet above and below any such interval or guide shoe.

7. All annular spaces extending to the surface must be plugged with cement.

8. The innermost string of casing which reaches ground level must be cemented to a minimum depth of 50 feet below the top of the casing.

9. The hardness and location of cement plugs placed across perforated intervals and at the top of uncased or open well bores must be verified by setting down with tubing or drill pipe a minimum weight of 15,000 pounds on the plug or, if less than 15,000 pounds, the maximum weight of the available tubing or drill pipe string. If a cement retainer or bridge plug is used to set the bottom plug, a test is not required for that interval.

10. The surface must be restored as near as practicable to its original condition unless the Administrator approves an exception to this requirement requested by the owner of the land.

11. Any interval that is not filled with cement must be filled with good quality, heavy drilling fluids.
