30 C.F.R. § 250.423 What are the requirements for pressure testing casing?
Title 30 - Mineral Resources
The table in this section describes the minimum test pressures for each string of casing. You may not resume drilling or other down-hole operations until you obtain a satisfactory pressure test. If the pressure declines more than 10 percent in a 30-minute test or if there is another indication of a leak, you must re-cement, repair the casing, or run additional casing to provide a proper seal. The District Manager may approve or require other casing test pressures. [68 FR 8423, Feb. 20, 2003]
