30 CFR 250.523 - 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.|
|(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.|
