The casing and cement used in construction of each new injection well shall be designed for the life expectancy of the well. A well to be converted to a saltwater disposal well must have surface casing set and cemented at a point not less than fifty feet below the base of the Fox Hills formation. In determining and specifying casing and cementing requirements, all of the following factors shall be considered:

a. Depth to the injection zone and lower confining zone. Long string casing must be set at least to the top of the injection zone and cemented at least to the top of the upper confining zone, or to a point approved by the director.

b. Depth to the bottom of all underground sources of drinking water.

c. Estimated maximum and average injection pressures.

d. Fluid pressure.

e. Estimated fracture pressure.

f. Physical and chemical characteristics of the injection zone.

2. Appropriate logs and other tests shall be conducted during the drilling and construction of injection wells. Any well drilled or converted to an injection well shall have a log run from which the quality of the cement bond can be determined. Cement bond logs shall contain at least the following elements: a gamma ray curve; a casing collar locator curve; a transit time curve; an amplitude curve; and a variable density curve. A descriptive report interpreting the results of these logs and tests shall be prepared by a qualified log analyst and submitted to the commission if deemed necessary by the director.

3. All injection wells must be equipped with injection tubing and a packer set in the long string casing within one hundred feet measured depth of the top perforation, or at a depth approved by the director.

43-02-05-07. Mechanical integrity.

1. Prior to commencing operations, the operator of a new injection well must demonstrate the mechanical integrity of the well. Prior to performing any workover project on an existing well, during which the packer or other means of annular isolation could be affected, the operator shall obtain approval from the director. All existing injection wells must demonstrate continual mechanical integrity and be tested at least once every five years. Following the completion of any remedial work, the operator shall demonstrate the mechanical integrity of the well. The director may require further mechanical integrity tests or other remedial work to ensure the mechanical integrity of the well to prevent the movement of fluid into an underground source of drinking water or an unauthorized zone. Mechanical integrity pressure tests must be performed at one thousand pounds per square inch for a minimum of fifteen minutes. A mechanical integrity test pressure of less than one thousand pounds per square inch may be approved by the director. Once an injection well is determined to lack mechanical integrity, within ninety days of the determination, it must be repaired and retested or plugged and abandoned.

An injection well has mechanical integrity if:

a. There is no significant leak in the casing, tubing, or packer; and

b. There is no significant fluid movement into an underground source of drinking water or an unauthorized zone through vertical channels adjacent to the injection bore.

2. One of the following methods must be used to evaluate the absence of significant leaks:

a. Pressure test with liquid or gas.

b. Monitoring of positive annulus pressure following a valid pressure test.

c. Radioactive tracer survey.

3. One of the following methods must be used to establish the absence of significant fluid movement:

a. A log from which cement can be determined or well records demonstrating the presence of adequate cement to prevent such migration.

b. Radioactive tracer survey, temperature log, or noise log.

4. The operator of an injection well immediately shall shut-in the well if mechanical failure indicates fluids are, or may be, migrating into an underground source of drinking water or an unauthorized zone, or if so directed by the director.

History: Effective November 1, 1982; amended effective May 1, 1990; July 1, 1996; May 1, 2004; October 1, 2016; April 1, 2020. General Authority: NDCC (2) Law Implemented: NDCC (2)

43-02-05-08. Plugging of injection wells.

The proper plugging of an injection well requires the well be plugged with cement or other types of plugs, or both, in a manner which will not allow movement of fluids into an underground source of drinking water. The operator shall file a notice of intention to plug (form 4) or form provided by the director and shall obtain the director's approval of the plugging method prior to the commencement of plugging operations.

History: Effective November 1, 1982; amended effective May 1, 1992; May 1, 1994; April 1, 2020. General Authority: NDCC (2) Law Implemented: NDCC (2)

43-02-05-09. Pressure limitations.

Injection pressure at the wellhead shall not exceed a maximum authorized injection pressure which shall be calculated so as to assure that the pressure in the injection zone during injection does not initiate new fracture or propagate existing fractures in the confining zones. In no case shall injection pressure initiate fractures in the confining zones or cause the movement of injection or formation fluids into an unauthorized zone or underground source of drinking water.

History: Effective November 1, 1982; amended effective May 1, 1992; April 1, 2018; April 1, 2020. General Authority: NDCC (2) Law Implemented: NDCC (2)

43-02-05-10. Corrective action.

If any monitoring indicates the movement of injection or formation fluids into an unauthorized zone or underground sources of drinking water, the director shall prescribe such additional requirements for construction, corrective action, operation, monitoring, or reporting as are necessary to prevent such movement.

43-02-05-11. Bonding requirements.

All injection wells must be bonded as provided in section 43-02-03-15. A commercial injection well is one that only receives fluids produced from wells operated by a person other than the principal on the bond.
