(a) No tubing string shall be placed in service or continue to be used unless such tubing string has the necessary strength and pressure integrity and is otherwise suitable for its intended use.
(b) In the event of prolonged operations such as milling, fishing, jarring, or washing over that could damage the casing, the casing shall be pressure-tested, calipered, or otherwise evaluated every 30 days and the results submitted to the District Manager.
(c) When the tree is installed, you must equip wells to monitor for casing pressure according to the following chart:
If you have * * *
you must equip * * *
so you can monitor * * *
(1) fixed platform wells,
all annuli (A, B, C, D, etc., annuli).
(2) subsea wells,
the tubing head,
the production casing annulus (A annulus).
(3) hybrid* wells,
the surface wellhead,
all annuli at the surface (A and B riser annuli). If the production casing below the mudline and the production casing riser above the mudline are pressure isolated from each other, provisions must be made to monitor the production casing below the mudline for casing pressure.
* Characterized as a well drilled with a subsea wellhead and completed with a surface casing head, a surface tubing head, a surface tubing hanger, and a surface christmas tree.
(d) Wellhead, tree, and related equipment shall have a pressure rating greater than the shut-in tubing pressure and shall be designed, installed, used, maintained, and tested so as to achieve and maintain pressure control. New wells completed as flowing or gas-lift wells shall be equipped with a minimum of one master valve and one surface safety valve, installed above the master valve, in the vertical run of the tree.
(e) Subsurface safety equipment shall be installed, maintained, and tested in compliance with § 250.801 of this part.
