|(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.|
