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. |
(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. |
