250.522—When do I have to repeat casing diagnostic testing?

Casing diagnostic testing must be repeated according to the following table:
When * * * you must repeat diagnostic testing * * *
(a) your casing pressure request approved term has expired, immediately.
(b) your well, previously on gas lift, has been shut-in or returned to flowing status without gas lift for more than 180 days, immediately on the production casing (A annulus). The production casing (A annulus) of wells on active gas lift are exempt from diagnostic testing.
(c) your casing pressure request becomes invalid, within 30 days.
(d) a casing or riser has an increase in pressure greater than 200 psig over the previous casing diagnostic test, within 30 days.
(e) after any corrective action has been taken to remediate undesirable casing pressure, either as a result of a casing pressure request denial or any other action, within 30 days.
(f) your fixed platform well production casing (A annulus) has pressure exceeding 10 percent of its minimum internal yield pressure (MIYP), except for production casings on active gas lift, once per year, not to exceed 12 months between tests.
Code of Federal Regulations 168
(g) your fixed platform well's outer casing (B, C, D, etc., annuli) has a pressure exceeding 20 percent of its MIYP, once every 5 years, at a minimum.
