P628 AS-5 Anchor Packer

 P628 AS-5 Anchor Packer

The P628 AS-5 Anchor Packer is the upper packer in a zone isolation completion. The packer was designed to run above the AS-6 Compression Packer. The AS-5 Packer sets by applying weight, closing the bypass seal and energizing the packing elements. Once set, the AS-5 can be locked in place allowing the tubing string to be removed using the T-2 On/Off Tool. The AS-5 sets and releases with one quarter turn right hand rotation at the packer.
