Ariz. Admin. Code § R12-7-113 - Blowout Prevention and Related Well-control Equipment

A. When drilling in areas where pressures are unknown or high pressures do or are likely to exist, a blowout preventer, control head and related lines, and connections necessary to control the pressures and to keep the well under control at all times shall be installed as soon as the surface casing is set.

B. Upon installation, all ram-type blowout preventers and related equipment shall be pressure tested to the lesser of the manufacturer's full working pressure rating of the equipment, 70% of the minimum internal yield pressure of any casing subject to test, or one psi per foot of the last casing string depth. Annular or bag-type preventers shall be tested to the lesser of 1000 psi or 50% of full working pressure on installation. The blowout preventer and related equipment shall be tested:

1. After each string of casing is set in the well,

2. Not less than once each 14 days from each control station, and

3. Following repairs that require disconnection of any pressure seal in the assembly. Only the component repaired or replaced needs be tested unless alteration or repair occurs at a normal full blowout preventer test period.

C. The operator shall maintain records of the tests required in this Section until the well is completed and shall submit copies of these records to the Commission if required.
