Cup tester (Cup Packer)

Description

The Cup Packer is a simple and economical packer that can be used for injection, production, isolating casing leaks or zones. The packer is available in single or double cup designs. Usually the cups are run in multiples of two and facing towards or away from center depending on application. Opposed cups allows pressure to be isolated from either direction at the same time.

Operation

Run the packer to setting depth. The cups are friction fit and are energized by differential pressure. The packer does not have an internal bypass. To minimize surging or swabbing it is recommended to run a mechanism for fluid or gas bypass such as the Bypass Valve. The Packer is retrieved with straight pull of the tubing string.
