(a) You must perform a casing diagnostic test within 30 days after first observing or imposing casing pressure according to the following table: ------------------------------------------------------------------------
you must perform a casing
(1) fixed platform well, the casing pressure is
greater than 100 psig.(2) subsea well, the measurable casing
pressure is greater than
the external hydrostatic
pressure plus 100 psig
measured at the subsea
wellhead.(3) hybrid well, a riser or the production
casing pressure is greater
than 100 psig measured at
the surface.------------------------------------------------------------------------
(b) You are exempt from performing a diagnostic pressure test for the production casing on a well operating under active gas lift. [76 FR 64462, Oct. 18, 2011. Redesignated at 77 FR 50894, Aug. 22, 2012]
