It is deflated by means of slots that can be opened to allow the gas or liquid to flow out They are used when a temporary packer is needed in a hole with weakened casing that could be damaged by mechanical slips.

n: A type of packer that uses an inflatable bladder to expand the packer element against the casing or wellbore. In preparation for setting the packer, a drop ball or series of tubing movements are generally required, with the hydraulic pressure required to

a device with metal slats or cords woven around a rubber bladder with an elastomer cover designed to inflate in the wellbore and provide isolation.

n: a device, usually with segmented threads, run with seal subs on the bottom of a tubing string and latched into a permanent packer to prevent tubing movement.

a tubular joint that allows tubing movement.

n: a device that holds the lower end of a tubing string in place by means of slips, used to prevent tubing movement when no packer is present.

n: It fasten the oil pipe in the casing ,which can decrease the stroke loss in the process of mechnical production.

a packer-like device without seals that keeps the tubing from moving. Common in rod pumped wells.

n: changes in tubing length due to changes in pressure, temperature, or drag from sucker rod strokes. Also called breathing.
