Shut-In Well
An inactive well should be classified as shut-in when the completion interval is open to the tubing or to the casing. A shut-in well may have tubing and packer, which isolates the interior of the casing above the packer from the completion interval. A well may also be shut-in without a packer which exposes the interior of the casing to any fluids from the completion interval.
Shut-in wells may have been removed from active service in anticipation of workover, temporary abandonment, or plugging and abandonment operations. Generally, the wellbore condition is such that its utility may be restored by opening valves or by energizing equipment involved in operating the well. Shut-in status should begin three months after production, injection, disposal, or workover operations cease.

Shut-In
Inactive wells in which the completion interval is open to the tubing and to the casing, or is open to the tubing only. The well may be shut-in without packer and with or without tubing, in which case the interior of the casing is not isolated from the completion interval. Or, the shut-in well may have tubing and packer, which isolates the interior of the casing above the packer from the completion interval.
Shut-in wells have been removed from active service in anticipation of a workover, temporary abandonment, or plugging and abandonment operations. Generally, the wellbore condition is such that its utility may be restored by opening valves or by energizing equipment involved in operating the well. Shut-in status should begin 90 days after production, injection, disposal or workover operations cease.
