| If you have a . . .
| you must perform a casing diagnostic test if . . .
|
|---|
| (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.
