Completion Operations - Packer (introduction)
A packer is defined as a sub-surface tool used to provide a seal between the tubing and casing (or wall) of a well, thus preventing the vertical movement of fluids past this sealing point. Packers are sometimes referred to as production packers but this term is generally used with reference to a particular class.
