Section 4-8 - Casing and Cementing of Injection Wells
Current through September 21, 2024
(a) Wells used for injection of gas, air, water, or other extraneous fluid into the producing formation shall be cased with safe and adequate casing or tubing so as to prevent leakage, and shall be so set or cemented that damage will not be caused to oil, gas, or fresh water sources.
(b) The provisions of Chapter 3, Section 22 of these rules, shall apply to all injection wells.
(c) Before a new well drilled for injection or disposal is operated, the casing outside the tubing shall be tested at the greater of a minimum pressure of three hundred (300) psi or a pressure equivalent to the maximum injection pressure, but no higher than one thousand (1,000) psi. For the purpose of pressure testing, packers must be set within one hundred feet (100') of perforations. The same rules apply to testing existing wells newly converted to injection or disposal. Operators must provide the Commission staff the opportunity to witness all integrity tests. In the event a representative of the Commission is unable to witness the test, the Operator is required to provide documentation of the test to the Commission. A retrievable bridge plug will be utilized in casing to test tubingless completions.
